AB  - Silicon (Si) is a widely recognized beneficial element in plants. With the emergence of nanotechnology in agriculture, silicon nanoparticles (SiNPs) demonstrate promising applicability in sustainable agriculture. Particularly, the application of SiNPs has proven to be a high-efficiency and cost-effective strategy for protecting plant against various biotic and abiotic stresses such as insect pests, pathogen diseases, metal stress, drought stress, and salt stress. To date, rapid progress has been made in unveiling the multiple functions and related mechanisms of SiNPs in promoting the sustainability of agricultural production in the recent decade, while a comprehensive summary is still lacking. Here, the review provides an up-to-date overview of the synthesis, uptake and translocation, and application of SiNPs in alleviating stresses aiming for the reasonable usage of SiNPs in nano-enabled agriculture. The major points are listed as following: (1) SiNPs can be synthesized by using physical, chemical, and biological (green synthesis) approaches, while green synthesis using agricultural wastes as raw materials is more suitable for large-scale production and recycling agriculture. (2) The uptake and translocation of SiNPs in plants differs significantly from that of Si, which is determined by plant factors and the properties of SiNPs. (3) Under stressful conditions, SiNPs can regulate plant stress acclimation at morphological, physiological, and molecular levels as growth stimulator; as well as deliver pesticides and plant growth regulating chemicals as nanocarrier, thereby enhancing plant growth and yield. (4) Several key issues deserve further investigation including effective approaches of SiNPs synthesis and modification, molecular basis of SiNPs-induced plant stress resistance, and systematic effects of SiNPs on agricultural ecosystem.

AB  - Летња терофита Impatiens glandulifera Royle (хималајски балзам, фамилија Balsaminaceae) потиче из уског подножја западних Хималаја, где се традиционално користи као лековита. Изван свог исходишта већ скоро два века колонизује углавном минералним хранивима (посебно азотом и фосфором) богата низијска крајречна станишта, и сматра се проблематичним освајачем који доводи до смањења биљне разноврсности, поспешивања ерозије и успоравања разлагања органске материје. Ова врста већ је инвазивна у преко 30 држава света, а Европска Комисија прогласила ју је за једну од најопаснијих инвазивних врста биљака1. У Србији, ова врста је још увек ретка и класификована је као „спорадично инвазивна“. Међутим, у изолованом планинском и природно олиготрофном станишту Сиринићке жупе (Косово и Метохија), атипичном за ову врсту, бројне и добро развијене састојине први пут смо регистровали 2021. године, углавном у долини реке Лепенац и њених притока (до 1200 m надморске висине) 2.

Приказаћемо сумаризацију резултата који су проистекли из мапирања распрострањености, анализе нативне вегетације у којој се јавља, карактеристика земљишта, морфологије самог „уљеза“ (висина, пречник стабла, сува маса јединке), као и знања локалног становништва о овој врсти. Хималајски балзам (локални назив „пуцавац“) донесен је у Сиринићку жупу почетком седамдесетих година прошлог века као украсна биљка, која је убрзо побегла из башти и дворишта. Њено даље ширење и трајно успостављање омогућено је драстичном деградацијом предела од стране човека, понајпре уништењем природне крајречне вегетације сечом шума и еутрофикацијом земљишта отпадним водама из домаћинства. У природну вегетацију која још увек није антропогено нарушена (ливадске и алувијалне састојине) ова биљка може спорадично да продре, међутим не и да се одржи. Дакле, иако се најкрупније јединке хималајског балзама са највећим потенцијалом за даљу инвазију налазе у најоштећенијој вегетацији (са најмањим диверзитетом), наши резултати указују да, за сада, ова декоративна и медоносна врста ту може евентуално да замени нитрофиле као што је коприва. Много је алармантнија, међутим, незаинтересованост млађе популације (до 30 година), која ову веома упадљиву врсту не примећује и не препознаје, што индиректно указује на општу ерозију традиционалног еколошког знања у овом подручју.
AB  - Summer therophyte Impatiens glandulifera Royle (Himalayan balsam, family
Balsaminaceae) originates from a narrow zone in the foothills of the Western Himalaya, where it
is used in traditional medicine. For almost two centuries it has been colonizing nutrient enriched
(mainly with nitrogen and phosphorus) lowland alluvial habitats outside of its native range, and
is currently considered a problematic intruder which causes decrease of plant diversity, promotes
soil erosion and hampers nutrient cycling. This plant species has been classified as invasive in
over 30 countries around the world, and considered one of top invaders of the European Union
concern1
. In Serbia, it is still rather rare, classified as “sporadically invasive”. However, in an
isolated mountainous habitat of the Sirinić valley (Kosovo and Metohija), naturally oligotrophic
and atypical for this species, we have recently registered numerous and well developed stands of
Himalayan balsam, predominantly in the alluvium of the Lepenac river and its tributaries (up to
the elevation of 1200 m a.s.l.) 2
.
We shall present the joint analysis of distribution mapping of the invader, its life history
traits (height, stem diameter, aboveground dry weight), characteristics of the invaded domicile
vegetation and concomitant soil properties, supplemented by the local knowledge on this species.
22
Himalayan balsam (vernacular name “pucavac” among the Serbian population) in the study area
escaped from the gardens soon after deliberate introduction as an ornamental plant in the early
1970’s. Its further spread and successful establishment has been enabled by drastic
anthropogenic landscape change and habitat degradation, primarily through severe deforestation
of riparian vegetation coupled with the pronounced soil eutrophication by direct discharge of
household wastewaters in the local river system. Interestingly, this species was able to
sporadically occur, but not to get established in undisturbed natural vegetation like meadows or
riparian forests. Thus, though the largest individuals of this intruder, implying its strongest
potential for further spread, consistently occurred in the most degraded vegetation (with the
lowest species diversity), our results suggest that under the current conditions this decorative,
nectar producing species might substitute nitrophiles like stinging nettle in the secondary
vegetation. Much severe risk might be the overall indifference of the younger population (under
the age of 30 years), who do not recognize or even notice this rather conspicuous species, what
indicates a general trend of erosion of traditional ecological knowledge in the study area.

AB  - Monocots and dicots differ in their boron (B) requirement, but also in their capacity to accumulate silicon (Si). Although an ameliorative effect of Si on B toxicity has been reported in various crops, differences among monocots and dicots are not clear, in particular in light of their ability to retain B in the leaf apoplast. In hydroponic experiments under controlled conditions, we studied the role of Si in the compartmentation of B within the leaves of wheat (Triticum vulgare L.) as a model of a high-Si monocot and sunflower (Helianthus annuus L.) as a model of a low-Si dicot, with the focus on the leaf apoplast. The stable isotopes 10B and 11B were used to investigate the dynamics of cell wall B binding capacity. In both crops, the application of Si did not affect B concentration in the root, but significantly decreased the B concentration in the leaves. However, the application of Si differently influenced the binding capacity of the leaf apoplast for excess B in wheat and sunflower. In wheat, whose capacity to retain B in the leaf cell walls is lower than in sunflower, the continuous supply of Si is crucial for an enhancement of high B tolerance in the shoot. On the other hand, the supply of Si did not contribute significantly in the extension of the B binding sites in sunflower leaves.

AB  - Beneficial effects of silicon (Si) on plants have primarily been studied in crop species under single stress. Moreover, nutrient acquisition-based responses to combination of biotic and abiotic stresses (a common situation in natural habitats) have rarely been reported, in particular in conjunction with soil amendments with Si. Pedunculate oak (Quercus robur L.), one of the ecologically and economically most important tree species in Europe, is facing a severe decline due to combined stresses, but also problems in assisted regeneration in nurseries. Here, we studied the effect of Si supply on the leaf nutriome, root traits and overall growth of 12-weeks-old oak seedlings exposed to abiotic stress [low phosphorus (P) supply], biotic stress (Phytophthora plurivora root infection), and their combination. The application of Si had the strongest ameliorative effect on growth, root health and root phenome under the most severe stress conditions (i.e., combination of P deficiency and P. plurivora root infection), where it differentially affected the uptake and leaf accumulation in 11 out of 13 analysed nutrients. Silicon supply tended to reverse the pattern of change of some, but not all, leaf nutrients affected by stresses: P, boron (B) and magnesium (Mg) under P deficiency, and P, B and sulphur (S) under pathogen attack, but also nickel (Ni) and molybdenum (Mo) under all three stresses. Surprisingly, Si affected some nutrients that were not changed by a particular stress itself and decreased leaf Mg levels under all the stresses. On the other hand, pathogen attack increased leaf accumulation of Si. This exploratory work presents the complexity of nutrient crosstalk under three stresses, and opens more questions about genetic networks that control plant physiological responses. Practically, we show a potential of Si application to improve P status and root health in oak seedlings, particularly in nurseries.

AB  - Trivalent chromium [Cr(III)] is a threat to the environment and crop production. Silicon (Si) has been shown to be effective in mitigating Cr(III) toxicity in rice. However, the mechanisms by which Si reduces Cr(III) uptake in rice are unclear. Herein, we hypothesized that the ability of Si to obstruct Cr(III) diffusion via apoplastic bypass is related to silicic acid polymerization, which may be affected by Cr(III) in rice roots. To test this hypothesis, we employed hydroponics experiments on rice (Oryza sativa L.) and utilized apoplastic bypass tracer techniques, as well as model simulations, to investigate 1) the effect of Si on Cr(III) toxicity and its obstruction capacity via apoplastic bypass, 2) the effect of Cr(III) on silicic acid polymerization, and 3) the relationship between the degree of silicic acid polymerization and its Cr(III) obstruction capacity. We found that Si reversed the damage caused by Cr(III) stress in rice. Si exerted an obstruction effect in the apoplast, significantly decreasing the share of Cr(III) uptake via the apoplastic bypass from 18% to 11%. Moreover, Cr(III) reduced silica particles' radii and increased Si concentration in roots. Modeling revealed that a 5-fold reduction in their radii decreased the diffusion of Cr(III) in apoplast by approximately 17%. We revealed that Cr(III) promoted silicic acid polymerization, resulting in the formation of a higher number of Si particles with a smaller radius in roots, which in turn increased the ability of Si to obstruct Cr(III) diffusion. This negative feedback regulatory mechanism is novel and crucially important for maintaining homeostasis in rice, unveiling the unique role of Si under Cr(III) ion stress and providing a theoretical basis for promoting the use of Si fertilizer in the field.

AB  - An annual plant Himalayan balsam (Impatiens glandulifera Royle) is globally widespread and one of the Europe’s well-investigated top invaders. Yet, there is very limited knowledge on the effects of environment on the invasion potential of this species. We focused on two questions: does this species indeed not invade the southern areas of the continent; and, does the environment affect some of its key invasibility traits. In an isolated model valley (Sharr mountain, Western Balkans), we jointly analyzed the soil (21 parameter), the life history traits of the invader (height, stem diameter, aboveground dw), and the resident vegetation (species composition and abundances, Ellenberg indicator values), and supplemented it by the local knowledge (semi-structured interviews). Uncontrolled discharge of fecal wastewaters directly into the local dense hydrological network fostered mass infestation of an atypical, nutrient poor habitat. The phenotypic plasticity of the measured invasion-related traits was very high in the surveyed early invasion (30-50% invader cover) stages. Different microhabitat conditions consistently correlated with its growth performance. The largest individuals were restricted to the deforested riparian habitats with extreme soil nutrient enrichment (primarily by P and K) and low-competitive, species-poor resident vegetation. We showed that ecological context can modify invasion-related traits, what could affect further invasion process. Finally, this species is likely underreported in the wider region; public attitude and loss of traditional ecological knowledge are further management risks.

AB  - Priming with silicon (Si) may increase plant resistance to biotic and abiotic stresses, in particular in conjunction with its subsequent application. Yet, the very effect of the duration of priming with Si is less understood. Here, we investigated the effect of the duration of priming with Si on components of the antioxidative response of wheat exposed to a gradient of salinity stress. After priming with 1.5 mM Si(OH)4 (0, 1, and 3 days), wheat seedlings were exposed to different NaCl levels (0, 30, and 60 mM) without (-Si) or with (+Si) supply of 1.5 mM Si(OH)4. The activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), and the concentration of malondialdehyde (MDA) were measured in shoots and roots after 1 and 5 days of NaCl treatments. Interaction of priming duration and addition of Si on antioxidative variables were analyzed using general regression model. Overall, priming had no influence on -Si plants under salt stress. On the day 1 of NaCl exposure, priming duration did not affect SOD and APX activities neither in roots nor in shoots. However, on the day 5 of NaCl exposure longer priming with Si significantly increased the activities of APX and SOD in both roots and shoots. The activity of CAT showed no response to priming with Si and subsequent Si supply in both plant organs irrespectively of the duration of NaCl exposure. Interestingly, in both organs the concentrations of MDA as a proxy for oxidative damage of plant membranes were very clearly and consistently lower after 3 days of priming with Si (compared to 1 day or no priming) during the whole period of NaCl exposure. This study demonstrated that longer priming with Si can enhance the ameliorative effect of Si supply on the antioxidative response of wheat plants to a gradient of salinity stress.

AB  - Pedunculate oak (Quercus robur L.) is the most abundant deciduous tree species in Europe with high economical and ecological importance. Different species of Phytophthora are considered as one of the most important factors responsible for deterioration of oak forest, causing serious root damage not only in the forest trees, but also in the nurseries. Oak seedlings were grown in plastic pots with extremely low phosphorus (P) soil (1.5 mg kg-1 total P; no available Olsen-P detected). Silicon (Si) and P were supplied as Na2SiO3 (300 mg Si kg-1 dry soil) and KH2PO4 (180 mg P kg-1 dry soil), respectively. Four treatments (-P/-Si, -P+/Si, +P/-Si, and +P/+Si) were used in the experiment. After two months of experiment, a half of the plants in each treatment were root-inoculated with Phytophthora plurivora. After further four weeks, the first symptoms of P. plurivora infection appeared in leaves (e.g., leaf necrosis and wilting). Plants were then carefully removed from the pots, divided into roots and shoots, and the roots were scanned and analyzed by the WinRHIZO® software. Foliar concentrations of Si, P, K, Ca, Mg, B, Cu, Fe, Mn, and Zn were determined by ICP-OES, while the concentrations of N and S were determined by CHNS Analyzer. The addition of Si obviously improved root health status (e.g., decreasing de number of lesions and necrosis intensity) in the infected plants grown under -P conditions, which was followed by an increased foliar P concentration. The Si supply significantly increased the root variables (e.g., total root volume, root length, and area of thin roots) in both -P and +P plants inoculated with P. plurivora. Therefore, P. plurivora infection and supply of P and Si modulated the nutrient uptake and thereby changed the leaf ionomics, especially for infected -P plants supplied with Si (e.g., significantly increased B, Cu, and Si foliar concentrations and decreased Fe, Mn, Ca, Mg, K, and S foliar concentrations). Furthermore, Si fertilization significantly declined loses in plant dry biomass caused by P. plurivora infection and/or P deficiency, showing biomass comparable to non-infected +P plants.

AB  - Microbial mechanism of in-situ remediation of arsenic (As) in As-contaminated paddy fields by silicon (Si) fertilization has been rarely reported, especially under continuous rice cultivation and Si applications. In this study, two Si fertilizers were applied for three phases in five consecutive rice seasons to investigate the longlasting impacts on in-situ remediation of As, and the underpinning microbial mechanism of root-associated compartments (bulk soil, rhizosphere and endosphere) was explored using the last double-cropping rice. Repeated application of Si fertilizers as base manure had a long-lasting effect on reducing As concentrations in rice grains. Application of Si fertilizer at an adequate amount resulted in an extended in-situ remediation effect from endosphere to rhizosphere. The microbial diversity and richness in rhizosphere soil and endosphere were significantly impacted by Si fertilization, the effects depending on application doses and prolonged seasons. Si fertilization can immobilize As in the root or rhizosphere, and Fe concentrations and the As-and Fe-transforming microorganisms (i.e. Geobacteraceae) are the determinants of As uptake in rice. We recommend more extensive supplementation of Si fertilizer at a higher rate to decrease grain As concentration for in-situ remediation. This study sheds light on the microbial-mediated mechanism underlying Si fertilization effect on decreased As uptake in paddy fields.

AB  - Zizania latifolia is a wild rice that contains phytoliths (Phyt) that have considerable potential for carbon sequestration. We hypothesized that the capacity of phytolith-occluded carbon (PhytOC) sequestration in residues might increase by 20%, and economic profit would be twice as high under a rice/single-season Z. latifolia rotation as under rice mono- culture. To test this hypothesis, we collected rice and Z. latifolia plants and their corresponding soil samples from Zhejiang Province to determine the ability of both crops to fix carbon in the phytoliths. We showed that the soil con- centrations of available Si, total carbon (Ctot) and total nitrogen (Ntot) were highly positively correlated with the con- centrations of phytoliths and phytolith-occluded carbon in the residues of both crops. The cold waterlogged paddy fields in China have low productivity but their environmental conditions are suitable for planting Z. latifolia. Our model scenario, built on secondary data, demonstrated that, on a national basis, if the cold waterlogged paddy fields (occupying approximately 15% of the total paddy fields) were under rice/single-season Z. latifolia rotation, the con- tents of phytoliths and PhytOC in rice and Z. latifolia residues would be up to 19.46 × 106 t yr−1 and 8.82 × 104 t yr−1 (0.32 Tg CO2 yr−1), respectively. As a result, the economic benefit would be increased by 1.12 × 1011 USD per year compared to rice monoculture. Therefore, adopting rotational cropping of rice with single-season Z. latifolia will not only increase the content of PhytOC sequestration in residues and improve cold waterlogged paddy fields but also bring economic benefits to farmers.

abstract = "Zizania latifolia is a wild rice that contains phytoliths (Phyt) that have considerable potential for carbon sequestration. We hypothesized that the capacity of phytolith-occluded carbon (PhytOC) sequestration in residues might increase by 20%, and economic profit would be twice as high under a rice/single-season Z. latifolia rotation as under rice mono- culture. To test this hypothesis, we collected rice and Z. latifolia plants and their corresponding soil samples from Zhejiang Province to determine the ability of both crops to fix carbon in the phytoliths. We showed that the soil con- centrations of available Si, total carbon (Ctot) and total nitrogen (Ntot) were highly positively correlated with the con- centrations of phytoliths and phytolith-occluded carbon in the residues of both crops. The cold waterlogged paddy fields in China have low productivity but their environmental conditions are suitable for planting Z. latifolia. Our model scenario, built on secondary data, demonstrated that, on a national basis, if the cold waterlogged paddy fields (occupying approximately 15% of the total paddy fields) were under rice/single-season Z. latifolia rotation, the con- tents of phytoliths and PhytOC in rice and Z. latifolia residues would be up to 19.46 × 106 t yr−1 and 8.82 × 104 t yr−1 (0.32 Tg CO2 yr−1), respectively.

AB  - Silicon (Si) can alleviate aluminum (Al) toxicity in rice (Oryza sativa L.), but the mechanisms underlying this beneficial effect have not been elucidated, especially under long-term Al stress. Here, the effects of Al and Si on the suberization and development of rice roots were investigated. The results show that, as the Al exposure time increased, the roots accumulated more Al, and Al enhanced the deposition of suberin in roots, both of which ultimately inhibited root growth and nutrient absorption. However, Si restricted the apoplastic and symplastic pathways of Al in roots by inhibiting the uptake and transport of Al, thereby reducing the accumulation of Al in roots. Meanwhile, the Si-induced drop in Al concentration reduced the suberization of roots caused by Al through down-regulating the expression of genes related to suberin synthesis and then promoted the development of roots (such as longer and more adventitious roots and lateral roots). Moreover, Si also increased nutrient uptake by Al-stressed roots and thence promoted the growth of rice. Overall, these results indicate that Si reduced Al-induced suberization of roots by inhibiting the uptake and transport of Al in roots, thereby amending root growth and ultimately alleviating Al stress in rice. Our study further clarified the toxicity mechanism of Al in rice and the role of Si in reducing Al content and restoring root development under Al stress.

AB  - Силицијум (Si) је четворовалентни металоид који због својих полупроводничких својстава има важну улогу у модерним електронским уређајима. Силицијум је на другом месту по заступљености хемијских елемената у земљиној кори, али је његово кружење у природи веома споро. Овај хемијски елеменат је неопходан за људе, животиње и неке алге, попут дијатомеја. Иако поједине биљне врсте акумулирају силицијум у количинама значајно већим од неопходних елемената (хранива) попут азота, фосфора или калијума, овај по много чему посебан и користан елеменат још увек није сврстан у групу биљних хранива. Код копнених биљака (Embryophyta), постоји различита заступљеност силицијума у ткивима. Маховине (Bryophyta) и папратњаче (Pteridophyta) акумулирају силицијум у концентрацијама и преко 5% суве масе. Код скривеносеменица (Angiospermae), монокотиле (Liliopsida), по правилу, акумулирају веће количине силицијума (0,5-5% суве масе), посебно траве (Poales) и оштрике (Cyperales), док дикотиледоне биљке (Magnoliopsida) у већини случајева одликује ниска концентрација силицијума у ткивима (испод 0,2% суве масе), са изузетком редова Urticales, Ericales, Lamiales, Myrtales, Caryophyllales и Cucurbitales, чији поједини представници акумулирају и веће количине силицијума (преко 0,5% суве масе). Биљке усвајају силицијум из земљишта искључиво у облику недисосоване силицијумове киселине (H4SiO4), што је и једини биоприступачни облик силицијума за све живе организме, укључујући и људска бића. До сада су у корену биљака окарактерисана два различита транспортна протеина за силицијум и то: Lsi1 (аквапорински канал), који транспортује H4SiO4 у симпласт корена и Lsi2 (анјонски транспортер), који је одговоран за траспорт силицијума изван ендодермиса (зона Каспаријевих трака) и пуњење ксилемских судова. Даљи транспорт силицијумове киселине одвија се ксилемом и погоњен је транспирационом струјом, која уједно и привремено спречава полимеризацију силицијумове киселине при концентрацијама изнад 2,5 mM. У надземним органима и ткивима силицијумoва киселина полимеризује до аморфних структура сличних минералу опалу, од којих су изграђене тзв. фитолитне структуре, које дају механичку чврстоћу надземном делу биљке.
Благотворно дејство силицијума код биљака изложених стресу подробно је документовано у литератури. Тако је показано да биљке третиране силицијумом показују повећану отпорност на последице глобалних климатских промена (суша, температурни екстреми, УВ зрачење), кисела и заслањена земљишта, токсичне концентрације алуминијума, арсена и тешких метала, али и на недостатак и вишак (дисбаланс) хранива. Улога силицијума у отпорности биљака на стрес изазван биотичким чиниоцима (хербиворни инсекти и биљни патогени) није само механичке природе, већ третман силицијумом појачава и биохемијски одговор биљке на нивоу транскрипције, што доприноси појачаној синтези природних фунгицида (фитоалексини) и репелената. Примена силицијума у светској пољопривреди перманентно расте, посебно у органској и биодинамичкој производњи. На пример, силицијум улази у састав неколико рецептура (препарација), које је успоставио творац биодинамичке пољопривреде Рудолф Штајнер (1861-1925); затим, смеша млевених крављих рогова и кварца (501) и прах раставића (508). Поред тога, све више се говори и о важној улози силицијума, односно фитолита у секвестрирању угљендиоксида (CO2) из атмосфере. Процењује се да секвестарциони потенцијал фитолита за угљеник у светској копненој биомаси износи око 157 милиона тона CO2 годишње.
За разлику од познатих штетних последица удисања силиконског праха и микровлакана код људи (опструктивно плућно обољење – силикоза), односно проблема у варењу сточне хране богате силицијумом код преживара, много се мање пропагирају корисна својства силицијума за људе и животиње. Силицијум је градивни елеменат који је неопходан за биосинтезу колагена и гликозоаминогликана и стога улази у састав колагених ткива, као што су: кости, плућа, васкуларни органи, мишићна влакна, кожа, нокти, коса, итд. Просечан дневни унос силицијума у облику биоприступачне силицијумове киселине износи од 9 до 14 mg, док су дневне потребе за силицијумом много веће и износе од 15 до 40 mg у зависности од пола, узраста и телесне масе. Истраживања показују да дневни унос од најмање 25 mg силицијума доприноси здрављу костију и превенцији остеопорозе. Поред тога, силицијум може да замени калцијум у изградњи костију и крвних судова, чиме се повећава њихова еластичност. Суплементација силицијумом такође доприноси превенцији неуродегенеративних оболења (нпр. Алцхајмерове болести), имајући у виду да у реакцији силицијумове киселине са алуминијумом настају метаболички неактивни алумосиликати, чиме се смањује концентрација слободног алуминијума коме се приписује улога у настанку плакова у мозгу. Силицијуму се приписује и улога у регулацији циклуса ћелија лимфоцита, чиме посредно утиче на имуне и инфламаторне одговоре.
Главни извор силицијума у људској исхрани представљају интегралне житарице и њихови производи, који су слабије заступљени у масовној исхрани становништва у Србији, претежно базираној на хлебу и пецивима од белог брашна. Због тога се намеће потреба за додатном суплементацијом силицијумом у циљу побољшања народног здравља. Један од природних суплемената свакако јесу и неке самоникле лековите биљке, које су познате да акумулирају силицијум, као што су нпр. раставићи, коприва (Urtica dioica), кисељак (Rumex acetosella), троскот (Polygonum aviculare), јагорчевина (Primula veris), кокотац или ждраљевина (Melilotus albus), нана (Mentha piperita), матичњак (Melissa officinalis), тимијан (Thymus spp.), врбица црвена (Lythrum salicaria), итд. Ово ревијално предавање има управо за циљ да стручну и ширу јавност упозна са благотворним деловањем силицијума на биљке и људе, као и да подстакне даља истраживања лековитог потенцијала биљака који се заснива на биоактивном силицијуму.

AB  - An annual plant, Himalayan balsam (Impatiens glandulifera Royle) is globally widespread and one of Europe's top invaders. We focused on two questions: does this species indeed not invade the southern areas and does the environment affect some of its key invisibility traits. In an isolated model mountainous valley, we jointly analyzed the soil (21 parameters), the life history traits of the invader (height, stem diameter, aboveground dw), and the resident vegetation (species composition and abundances, Ellenberg indicator values), and supplemented it with local knowledge (semi-structured interviews). Uncontrolled discharge of fecal wastewaters directly into the local dense hydrological network fostered mass infestation of an atypical habitat. The phenotypic plasticity of the measured invasion-related traits was very high in the surveyed early invasion (30-50% invader cover) stages. Different microhabitat conditions consistently correlated with its growth performance.

abstract = "An annual plant, Himalayan balsam (Impatiens glandulifera Royle) is globally widespread and one of Europe's top invaders. We focused on two questions: does this species indeed not invade the southern areas and does the environment affect some of its key invisibility traits. In an isolated model mountainous valley, we jointly analyzed the soil (21 parameters), the life history traits of the invader (height, stem diameter, aboveground dw), and the resident vegetation (species composition and abundances, Ellenberg indicator values), and supplemented it with local knowledge (semi-structured interviews). Uncontrolled discharge of fecal wastewaters directly into the local dense hydrological network fostered mass infestation of an atypical habitat. The phenotypic plasticity of the measured invasion-related traits was very high in the surveyed early invasion (30-50% invader cover) stages. Different microhabitat conditions consistently correlated with its growth performance. The largest individuals were restricted to the deforested riparian habitats, with extreme soil nutrient enrichment (primarily by P and K) and low-competitive, species-poor resident vegetation.

AB  - Cluster zone leaf removal is a well-established viticulture practice for improving cluster microclimate and wine quality in cooler climates, while its efficacy in warmer conditions is less is known. Here we compared the effect of early (ELR, after fruit set; diameter of berries 3-5 mm) and late (LLR, beginning of veraison) leaf removal on berry composition and wine phenolic profile of grapevine (Vitis vinifera L.) variety Cabernet Sauvignon grown in a temperate, warmer region of Eastern Serbia. Compared to the control (no leaf removal), both leaf removal treatments increased the sugar content in fresh juice and alcohol concentration in wine. Over three consecutive years (2011-2013) markedly different in temperature and rainfall, ELR was clearly most effective in decreasing weights of cluster and of one berry, and in increasing of skin share in a berry. The content of total phenols, tartaric acid esters, anthocyanins, and flavanols in berry skin and wine was the highest in ELR treatment. ELR prominently modified the phenolic profile: Increasing flavanols, myricetin and quercetine in skin and wine, and anthocyanins, peonidin-3-glucoside in skin and delphinidin-3-glucoside in wine. This work demonstrated that early leaf removal positively influenced the chemical composition of berries and wine of Cabernet Sauvignon and might be recommended for practice in the temperate warm conditions.

AB  - Wheat grain Zn concentration has important implications for Zn dietary intake in humans. Zn biofortification of wheat by Zn foliar application has been recognized as an efficient tool to enhance grain Zn level. In Serbia, wheat is a staple crop, and no attention is paid to wheat grain as a source of Zn. For the first time, we investigated the effect of Zn foliar application on grain Zn concentration and yield of high-yielding local bread wheat cultivars in Serbia as potential to improve Zn intake in local population. Field experiments were conducted over two growing seasons at two sites located in Vojvodina Province. Zn was applied by spraying of 0.5% water solution of ZnSO4 at the end of flowering stage. Zn foliar application had no significant effect on grain yield. Significant increases of Zn grain concentration resulted from Zn treatment in all of five cultivars tested, ranging from 15 to 49%. No significant difference between the two sites was found in the mean increase in grain Zn concentration by Zn foliar application compared with the control. No correlation was found between grain yield and grain Zn concentration, implying that high grain yields common in intensive wheat production in Serbia do not limit Zn biofortification of grain by Zn foliar application. Zn biofortification of wheat grain by a single foliar spray at the end of the flowering stage can be recommended as an efficient tool to increase Zn intake in human population and prevent low dietary Zn intake.

AB  - This study examined early stages (3-5 years) of spontaneous primary vegetation succession on a model locality drastically altered by long term fluvial deposition of copper tailings in Eastern Serbia. In a large-scale survey, 115 samples of herbaceous vegetation (with a total of 75 species) were harvested from standardized 1m x 1m quadrates, and concomitant soil samples collected and their relevant physicochemical properties analysed. Primary succession depended on the establishment of five pioneer species (Rumex acetosella, Agrostis capillaris, Calamagrostis epigeios, Persicaria lapathifolia and Chenopodium botrys). Unconstrained ordination showed very clear vegetation gradients, significantly correlated with the key soil constraints (from Cu excess to low pH and nutrient deficiency), while the distribution of the five edificatory pioneers showed high degree of dependence on the micro-level habitat conditions. This work demonstrates that in such a complex setup with severe abiotic filtering, sufficient sampling effort can reveal strong patterns in a process commonly considered very stochastic.

AB  - In this subchapter, we discuss the need for investing in long-term assessment of impact on ecosystem services. We also think that governments should keep supporting national accounting of ecosystem services and that they should use the Common International Classification of Ecosystem Services (CICES) for that purpose. Mapping and assessment of the assets can also be employed for ecosystem accounting. Ecosystem services impact as- sessment, even though it is very important and necessary, cannot hide the facts that disaster risk management should move towards an ecosystem-based approach and that ecosystem degradation must be reversed. It is also important to highlight that impact on ecosystem services triggers a cascading effect that could be reflected in direct and indirect losses. These elements are discussed in detail, and we provide examples of and bibliographical references on how the ecosystem-based approach stands as a promising approach that can impact all elements of the disaster risk equation: mitigating hazards, reducing exposure, reducing vulnerabilities and increasing the resilience of exposed communities.

AB  - Both calcium (Ca2+) and silicon (Si) improve plant performance under salt (NaCl) stress. Although these two mineral elements share numerous similarities, the information on how their extracellular interactions in the root apoplast affect uptake of sodium (Na+) is still lacking. Here, we investigated the effect of high Si supply in the bioavailable form of monosilicic acid (H4SiO4) on the activity of Ca2+ in the external root solution, and subsequent root uptake and compartmentation of Na in maize (Zea mays L.). In the short-term experiments (6 h), 14-d-old maize plants were exposed to various concentrations of Ca2+ at three different pH-values (6.5, 7.5, and 8.5) and two Si concentrations, i.e., low (1 mM) and high (4 mM) supply of H4SiO4. The activity of Ca2+ and Na+ in the external solution as well as the root concentrations of total and cell sap and BaCl2-exchangeble apoplastic fractions of both elements were analyzed. The pH of the nutrient solution affected neither the ion activities nor the root accumulation of both Ca2+ and Na+. At higher pH values (7.5 and 8.5) the interactions of Ca2+ and Si at high Si supply led to a decrease of Ca2+ activity and, hence, an increase of Na+ : Ca2+ activity ratio in the external root solution. Concomitantly, despite the elevated exchangeable apoplastic fraction of both Ca2+ and Na+, the total and cell sap concentrations were remarkably decreased for Ca2+ and increased for Na+ by the addition of 4 mM H4SiO4. This work demonstrates that at high Si supply extracellular Ca-Si interactions leading to lowered activity of Ca2+ might rapidly compromise the ameliorative effect of Ca2+ on Na+ accumulation in roots. Practically, Si over-fertilization of saline and, in particular, sodic soils may further promote the accumulation of Na+ in root tissues hours after Si application and, hence, increase a potential risk of Na+ toxicity.

AB  - Soil carbon (C) storage is a key ecosystem function which can provide globally important services such as climate regulation. The effect of climate change on the restoration of soil C storage potential on post-mining land, where the development of both soil and vegetation starts de novo, is still insufficiently understood.
In this work we discuss how the recent changes of climate, effectuating temperature increase and overall habitat xerophytization have, during about 40 years, markedy modified the course of spontaneous succession and concomitantly the soil C sequestration potental in a model floodplain severely altered by long-term deposition of sulphidic waste from a copper (Cu) mine. Excessive Cu strongly reduces turnover of soil organic matter and adversely affects the revegetation process. Natural floods in this complex geomorphic setup on the other hand bring both pollutants and deficient nutrients to the affected floodplain. As the recent climate changes reduce the intensity of natural floods, two very different but highly specialized forest types are developing along the microelevation gradient (transects perpendicular to water channel) with up to 3-fold different topsoil C sequestration.
This work shows how climate change can increase the vunerability of spontaneous restoration process primarily by reducing nutrient fluxes.

AB  - Long-term potentials and constraints of nature to spontaneously recover after severe degradation by toxic mine waste, and general principles of mutual modifications of spontaneous vegetation and soils during this process, have remained widely unknown. This study investigates the effect of flooding on natural restoration of a model locality in Eastern Serbia, complexly degraded by 70-years fluvial deposition of sulfidic copper (Cu) mine tailings in a floodplain along 80km of the polluted river flow. We analyzed multivariate response of forest vegetation (floristic and structural parameters) together with physical and chemical properties of concomitant soils and sediments. Floods strongly modify the interactions between soil and vegetation. Three very different types of forest vegetation constitute the response of the nature to key soil adverse factors (excessive Cu availability, low nutrients, and low pH); combined with drought, these constraints completely inhibit revegetation. Continual flooding after mine closure, despite the pollution it still brings in, fosters a faster development of highly specialized vegetation and most importantly faster buildup of soil organic matter necessary for phytostabilization of substantial amounts of Cu tailings present in the floodplain. We show that enhanced nutrient fluxes facilitated by natural flooding regime might overrun the constraining effect of deposited Cu also for natural vegetation.

AB  - Although silicon (Si) is known to improve plant growth under low phosphorus (P) conditions, the in planta mechanisms responsible for this effect are still unknown. Here, we investigated the role of Si on P uptake along with the expression of Pi transporters in wheat (Triticum aestivum L.) grown in low P acid soil in comparison with P fertilization and liming. A combined approach was performed including analyses of rhizosphere soil, tissue P content, the expression of the root Pi transporter genes (TaPHT1.1 and TaPHT1.2), and the root exudation of citrate and malate. Supply of Si in a form of Na2SiO3 increased shoot P concentration to an adequate level in the range of P-fertilized plants. Silicon ameliorated low soil pH and high Al3+ comparable to the effect of liming. The in planta effect of Si on up-regulating the expression of TaPHT1.1 and TaPHT1.2 was several fold higher and consequently P uptake doubled compared to both P fertilization and liming. In addition, Si directly stimulated root Pi acquisition by prominently increasing both malate and citrate exudation rate. Application of Si increased root exudation of organic acids that mobilize Pi in the rhizosphere and up-regulated Pi transporters in wheat roots.

AB  - The deficiency of zinc (Zn) and iron (Fe) is a global issue causing not only considerable yield losses of food crops but also serious health problems. We have analysed Zn and Fe concentrations in the grains of two bread wheat cultivars along native gradient of micronutrient availability throughout Serbia. Although only 13% of the soil samples were Zn deficient and none was Fe deficient, the levels of these micronutrients in grain were rather low (median values of 21 mg kg(-1) for Zn and 36 mg kg(-1) for Fe), and even less adequate in white flour. Moreover, excessive P fertilization of calcareous soils in the major wheat growing areas strongly correlated with lower grain concentration of Zn. Our results imply that a latent Zn deficiency in wheat grain poses a high risk for grain quality relevant to human health in Serbia, where wheat bread is a staple food. k.

AB  - Despite the growing popularity of ecological restoration approach, data on primary succession on toxic post-mining substrates, under site environmental conditions which considerably differ from the surrounding environment, are still scarce. Here, we studied the spontaneous vegetation development on an unusual locality created by long-term and large-scale fluvial deposition of sulphidic tailings from a copper mine in a pronouncedly xerothermic, calcareous surrounding. We performed multivariate analyses of soil samples (20 physical and chemical parameters) and vegetation samples (floristic and structural parameters in three types of occurring forests), collected along the pollution gradients throughout the affected floodplain. The nature can cope with two types of imposed constraints: (a) excessive Cu concentrations and (b) very low pH, combined with nutrient deficiency. The former will still allow convergence to the original vegetation, while the latter will result in novel, depauperate assemblages of species typical for cooler and moister climate. Our results for the first time demonstrate that with the increasing severity of environmental filtering, the relative importance of the surrounding vegetation for primary succession strongly decreases.

AB  - We studied the effect of liming and P fertilization of extremely acid soil (accidently acidified by sulfidic mining waste) on P availability and the subsequent adaptive responses of wheat roots. The wheat plants were grown in rhizoboxes allowing precise sampling of rhizosphere and bulk soil for sequential extraction of P fractions and determination of exchangeable Al. Root exudates were collected by pieces of paper for electrophoresis and subjected to HPLC analysis. Expression of organic anions and P-i transporter genes was analyzed by a real-time quantitative PCR. The concomitant application of lime with P fertilization increased the concentrations of plant-available P fractions in both rhizosphere and bulk compartments. The applied soil amendments strongly affected plant growth, biomass partitioning and shoot P accumulation. Liming enhanced root exudation of citrate in P unfertilized plants, while the high malate efflux was maintained until both P deficiency and Al toxicity were eliminated by the amendments. We showed the importance of liming for recovering of P acquisition potential of wheat roots, which can be strongly impaired in acid soils. Our results clearly demonstrated that P-deficient roots not subjected to Al stress in the limed soil can maintain high efflux of malate and even increase efflux of citrate along with the enhanced expression of related anion transporters (TaMATE1 and TaALMT1).

AB  - Questions: Effects of soil on vegetation patterns are commonly obscured by other environmental factors; clear and general relationships are difficult to find. How would community assembly processes be affected by a substantial change in soil characteristics when all other relevant factors are held constant? In particular, can we identify some functional adaptations which would underpin such soil-induced vegetation response? Location: Eastern Serbia: fields partially damaged by long-term and large-scale fluvial deposition of sulphidic waste from a Cu mine; subcontinental/submediterranean climate. Methods: We analysed the multivariate response of cereal weed assemblages (including biomass and foliar analyses) to a strong man-made soil gradient (from highly calcareous to highly acidic, nutrient-poor soils) over short distances (field scale). Results: The soil gradient favoured a substitution of calcicoles by calcifuges, and an increase in abundance of pseudometallophytes, with preferences for Atlantic climate, broad geographical distribution, hemicryptophytic life form, adapted to low-nutrient and acidic soils, with lower concentrations of Ca, and very narrow range of Cu concentrations in leaves. The trends of abundance of the different ecological groups of indicator species along the soil gradient were systematically reflected in the maintenance of leaf P concentrations, and strong homeostasis in biomass N:P ratio. Conclusion: Using annual weed vegetation at the field scale as a fairly simple model, we demonstrated links between gradients in soil properties (pH, nutrient availability) and floristic composition that are normally encountered over large geographic distances. We showed that leaf nutrient status, in particular the maintenance of leaf P concentrations and strong homeostasis of biomass N:P ratio, underpinned a clear functional response of vegetation to mineral stress. These findings can help to understand assembly processes leading to unusual, novel combinations of species which are typically observed as a consequence of strong environmental filtering, as for instance on sites affected by industrial activities.
