AB  - Due to increased urbanization and industrialization, the emission of toxic material into the
atmosphere is in expansion, which has a negative impact on the environment and human health. In
this research, we monitored the effect of air pollution on the peroxidase (POD) activity and total
antioxidant capacity of different tree species during the growing season. The main goal was to
determine which tree species developed the highest tolerance to unfavorable environmental
conditions at the end of growing season, based on the response of their antioxidative metabolism. The
greatest change in POD activity was observed in the Fagus sylvatica L. leaves, where enzyme activity
was more than doubled in the autumn, in comparison to spring. On the other hand, decrease in POD
activity was the greatest in Cedrus atlantica (Endl.) Manetti ex Carrière needles. Moreover, total
antioxidative capacity was altered during growing season in almost all examined tree species. The
Magnolia spp. showed the most consistent response to the given environmental pollution with both
portrayed parameters induced during growing season. In general, we can conclude that the tree
species investigated in this research possess distinctive tolerance potential to air pollutants.

AB  - The first months are the most sensitive phase of oak seedling development. Light conditions have an important role in this sense, both from the physiological and management viewpoint. We investigated the response of pedunculate oak seedlings to three growth light intensities (100, 550 and 2000 μmol cm−2s−1) during development of the first and second growth flush. The low and high light intensities of PAR are supposed to mimic the effects of solar radiation under extreme natural conditions (closed canopy and open field). The response of seedlings to different light intensities was evaluated by determining the photochemical activity of photosystem II, leaf chlorophyll concentration and epidermal flavonoid accumulation for both growth flushes. At the end of the experiment (after 4.5 months) the effects of different treatments on growth parameters were also determined. We showed here that oak seedlings responded to varying light intensities by modifying their physiological and morphological traits of successive growth flushes. At medium light, seedlings had the highest PSII photochemical activity in the 2nd flush. High light induced very low photochemical efficiency of photosystem II in both growth flushes indicating the development of high non-photochemical quenching of chlorophyll fluorescence as part of photoprotective mechanism. In accordance with high photosynthetic yield at ML, the investment of photosynthates in growth, especially biomass allocation towards root system was confirmed. ML was optimal for seedling development in the first months. The results may contribute to a better understanding of oak seedling development and acclimation and could have importance for oak natural regeneration.

AB  - Street trees are important component of urban forest presenting a first barrier between air pollution
originated from vehicle traffic and pedestrians. It implies that an improvement of air quality in urban
areas greatly depends on green biomass, in short, the bigger and greener tree crown, better for human
health and wellbeing. Determination of Leaf Nitrogen Balance Index (LNBI) and chlorophyll
concentration (ChlC) by a non-invasive methodology and a user friendly instrument (Dualex 4,
Force), widely used in agronomy and horticulture, was tested here for the assessment of tree fitness in
urban zones. Investment of energy and resources either in growth or defence according to the tradeoff
strategy of plants may be indicated by LNBI, which approximately presents a Nitrogen/Carbon
ratio. We selected few tree species from Belgrade’s streets to determine those two parameters during
summer. We also presented the changes in those parameters of the introduced bamboo species within
ten years at several urban locations in Belgrade differing in air pollution aiming to evaluate
usefulness the LNBI parameter in access of multiyear exposure to the effect of intense vehicle traffic.
Numerous limiting factors for development of healthy tree crowns in urban ecosystem, such as low
capacity to cope with toxic pollutant, sensitivity to diseases, early senescence and etc., greatly depends
on tree species. We propose this methodology may also contribute in the process of choice of the
adequate tree species to be planted along streets.

AB  - Three basil plant varieties (Ocimum basilicum var. Genovese, Ocimum x citriodorum, and Ocimum
basilicum var. purpurascens) were grown under moderate light (about 300 umol photons m-2 s-1)
in a glasshouse or growth chamber and then either transferred to an open field (average daily dose:
29.2 kJ m-2 d-1) or additionally exposed to UV-B irradiation in a growth chamber (29.16 kJ m-2 d-1),
to reveal the variety-specific and light-specific acclimation responses. Total antioxidant capacity
(TAC), phenolic profile, ascorbate content, and class III peroxidase (POD) activity were used to determine
the antioxidant status of leaves under all four light regimes. Exposure to high solar irradiation
at the open field resulted in an increase in TAC, total hydroxycinnamic acids (HCAs, especially
caffeic acid), flavonoids, and epidermal UV-absorbing substances in all three varieties, as well as a
two-fold increase in the leaf dry/fresh weight ratio. The supplemental UV-B irradiation induced
preferential accumulation of HCAs (rosmarinic acid) over flavonoids, increased TAC and POD activity,
but decreased the ascorbate content in the leaves, and inhibited the accumulation of epidermal
flavonoids in all basil varieties. Furthermore, characteristic leaf curling and UV-B-induced inhibition
of plant growth were observed in all basil varieties, while a pro-oxidant effect of UV-B was indicated
with H2O2 accumulation in the leaves and spotty leaf browning. The extent of these morphological
changes, and oxidative damage depended on the basil cultivar, implies a genotype-specific tolerance
mechanism to high doses of UV-B irradiation.

AB  - The objective of this study was to determine the constitutive differences in physiological, biochemical and morphological parameters between two tomato genotypes with different levels of abscisic acid (ABA) – wild type Ailsa Craig (WT) and ABA deficient mutant flacca. Due to reduced ABA biosynthesis, flacca mutant is a suitable model system for investigating the influence of endogenous leaf ABA level in response to drought in plants. Within this research, plants were grown under controlled conditions at 800 μmol m-2s-1, until the end of the vegetative phase when samples were taken. The accumulation of the most abundant soluble sugars, sorbitol, phenolic compounds, and ascorbate in the leaves, as well as the cell walls compounds, were analyzed. Lower constitutive ABA content in flacca was accompanied by two times higher stomatal conductance and similar leaf water potential. Higher content of phenolic compounds (HBAs, HCAs, flavonoids) was determined in WT plants, which was in contrast with the elevated accumulation of the epidermal flavonoids in flacca. Larger accumulation of sorbitol in WT, and of the most abundant soluble sugars (glucose, fructose and sucrose) indicate that flacca accumulates lower content of osmolytes which was opposite to the condition at low light. However, an alternative mechanism related to cell wall modulation imposed its importance in the development of plant acclimation mechanisms under stressful environmental conditions in tomato deficient in ABA. On the other hand, an elevated ascorbate redox state in flacca indicates a higher sensitivity to oxidative stress of the mutant compared to WT even in optimal environmental conditions.

AB  - Drought causes huge agricultural and economic losses worldwide. Silicon (Si) is considered a
beneficial element for plants. It mitigates stress caused by salinity, drought, and high and low temperatures
by promoting antioxidant production. However, the underlying mechanisms are still not
elucidated. We investigated Si fertilisation effect on photosynthetic parameters, trichome number,
leaf optical properties, as well as profiles of amino acids and polyphenols in barley exposed to
water shortage. Silicon was applied in three growth stages: (i) before the flag leaf emergence;
(ii) prior to the grain filling phase; (iii) at the grain filling phase start. Drought negatively impacts
photochemical efficiency, stomatal conductance, photosynthetic pigment content, and leaf reflective
and transmissive properties. Si application between flag leaf emergence and grain filling
had the strongest effect on light reflectance. Among all analyzed phenolics, saponarin was the
most abundant in all samples, irrespective of water regime and Si supply. Caffeoyl ester was the
only hydroxycinnamic acid showing significant accumulation with the latest applied Si compared
to no added Si upon drought. The major amino acids in barley leaves were glutamate, glutamine,
aspartate, asparagine, and serine. Aspartate content was the highest in leaves exposed to drought
without Si addition, while lysine was the most accumulated in the leaves supplemented by Si at
the grain filling phase start. Proline was 2.5 times more abundant in the leaves exposed to drought
regardless of Si treatment. Taken together, although Si did not mitigate drought stress effects, its

abstract = "Drought causes huge agricultural and economic losses worldwide. Silicon (Si) is considered a
beneficial element for plants. It mitigates stress caused by salinity, drought, and high and low temperatures
by promoting antioxidant production. However, the underlying mechanisms are still not
elucidated. We investigated Si fertilisation effect on photosynthetic parameters, trichome number,
leaf optical properties, as well as profiles of amino acids and polyphenols in barley exposed to
water shortage. Silicon was applied in three growth stages: (i) before the flag leaf emergence;
(ii) prior to the grain filling phase; (iii) at the grain filling phase start. Drought negatively impacts
photochemical efficiency, stomatal conductance, photosynthetic pigment content, and leaf reflective
and transmissive properties. Si application between flag leaf emergence and grain filling
had the strongest effect on light reflectance. Among all analyzed phenolics, saponarin was the
most abundant in all samples, irrespective of water regime and Si supply. Caffeoyl ester was the
only hydroxycinnamic acid showing significant accumulation with the latest applied Si compared
to no added Si upon drought. The major amino acids in barley leaves were glutamate, glutamine,
aspartate, asparagine, and serine. Aspartate content was the highest in leaves exposed to drought
without Si addition, while lysine was the most accumulated in the leaves supplemented by Si at
the grain filling phase start. Proline was 2.5 times more abundant in the leaves exposed to drought
regardless of Si treatment. Taken together, although Si did not mitigate drought stress effects, its
effect was dependent on the barley growth phase prior to supplementation.",

AB  - Three varieties of basil (Ocimum x citriodorum, Ocimum basilicum var. Genovese and Ocimum
basilicum var. purpurascens) were used to examine the effect of different PAR intensities (100, 400
and 1400 µmol photons m-2s-1), as well as different UV-B/PAR ratios, on leaf phenolics accumulation, and components of the ascorbate-glutathione cycle. Phenolic compounds represent the
most abundant class of secondary metabolites, and their function in plants involves protection
against numerous abiotic stresses, role in growth and development, flowering, reproduction and
seed dispersion. A preferential accumulation of HCAs over Flav, induction of class III POD activity
and decreased ascorbate content were characteristic responses to pro-oxidative effect of the high
UV-B/PAR ratio in all three basil varieties. The most remarkable result was the lack of accumulation
of epidermal UV absorbing substances, which appeared to be a crucial photoprotective mechanism in sunlight. The contrasting effect of ecologically relevant UV-B radiation on basil plants,
pro-oxidative vs. acclimative, was determined by the quality and intensity of the background light.
Acclimation of basil to high light comprises a number of processes, among which are the accumulation of epidermal flavonoids and total leaf phenolics, antioxidant response (increase in Asc and
GSH) and lack of downregulation of PSII upon increasing light intensity. Among varieties that we
used as model system in this study, purple basil, with the highest constitutive amount of anthocyanidins, showed the least induction of epidermal flavonoids and lack of light effect upon transfer
from initial 50 to 250 µmol photons m-2s-1.

AB  - Trehalose and its precursor, trehalose 6-phosphate (T6P), are essential regulators of plant response to abiotic and biotic stress. Here we used the specific host-insect interaction between Linaria vulgaris (Plantaginaceae) and stem-galling weevil, Rhinusa pilosa (Mecinini, Curculionidae) with the aim to distinguish carbohydrate allocation patterns in response to herbivory, gall formation (G1, 24 h after oviposition), and gall development (G2, 7 days after oviposition) under controlled conditions. The hypothesis is that herbivory and galling induce distinct responses in both leaves and stems, and that shifts in carbon allocations are regulated by signaling sugars. Systemic response to herbivory was accumulation of T6P and maltose. The main feature of G1 in the stems was accumulation of trehalose, accompanied by increased T6P, turanose and glucose content, oppositely to the leaves. In G2, galls had 3-folds higher weight than controls, with further accumulation of fructose, glucose, turanose, and total water-insoluble carbohydrates (TIC), while the sucrose/hexose ratio decreased. Analysis of fast chlorophyll fluorescence kinetic (OJIP) transients in G2 showed a slight decrease in quantum yield of electron transport flux from Q(A) to Q(B), and towards photosystem I acceptor side, correlated with the decreased content of photosynthetic pigments and hexoses accumulation. Redistribution of photosynthates, and accumulation of T6P were induced in response to herbivory, indicating its signaling role. The results support the hypothesis that R. pilosa can induce plant reprogramming towards the accumulation of beneficial carbohydrates in developing gall by mechanisms which include both T6P and trehalose.

AB  - The dynamics of epidermal flavonoid (epFlav) induction was monitored during 11 days in the leaves of three Ocimum basilicum varieties: Americanum, Genovese and Purpurescens, Salvia officinalis, Eruca sativa and Verbascum thapsus previously grown in a glasshouse (receiving 16% of sunlight irradiance without UV). At full sunlight plants received mean daily doses of 6.97 MJ m-2, 0.86 MJ m-2 and 22.46 kJ m-2 in the photosynthetically active radiation, UV-A and UV-B wavelengths, respectively. Although constitutive concentration of epFlav was similar, dynamics of their induction was species-specific. Significant increase in epFlav accumulation was observed 30h after exposure to sunlight in all species except O. basilicum var. Purpurescens, in which the increase was delayed. This delay was correlated with induction of constitutive epidermal anthocyanins. Total leaf flavonoids were unchanged, in contrast to epidermal, emphasizing their UV-B absorbing function. Total antioxidative capacity increased at least 2-fold under sunlight, which was in accordance with total phenolic increase. Leaf dry biomass was 50-100% higher in sunlight-exposed compared to glasshouse grown plants, while fresh biomass was unchanged, indicative of leaf thickening. We showed that flavonoids accumulation was dependent on light conditions and constitutive pool of UV-B absorbing compounds.

AB  - Rhinusa pilosa (Gyllenhal) is a highly specific weevil that induces stem galls on the common toadflax Linaria vulgaris Mill. females oviposit the eggs near the apex of a growing shoot. The act of oviposition is accompanied by secretion of an ovipositional fluid, which is considered to be cecidogen, directly involved in gall induction. The remains of cecidogenic fluid were collected from the surface of the oviposition point on the stem. We performed a comparative analysis of the phenolics extracted from cecidogen, the stem and galls of L. vulgaris and adult and larva of R. pilosa by HPLC-DAD. One compound with A (max) at 273, 332 nm (R (t) 30.65 min) was exclusively found in the methanol extract of cecidogen. To further characterize the cecidogen and stem phenolic profiles, we used UHPLC coupled with an OrbiTrap mass analyzer. Among 49 phenolic compounds extracted from both the ovipositional fluid and the plant, protocatechuic acid and two phenolic glycosides were exclusively found in cecidogen: diosmetin-O-acetylrutinoside and an unidentified compound. The unknown compound produced an MS2 base peak at 387 and 327 and 267 m/z base peaks at MS3 and MS4 fragmentation, respectively, and had the molecular formula C32H31O18. The plausible role of phenolic compounds in the induction of gall formation on L. vulgaris is discussed.

AB  - In this study we investigated the effects of ambient ultraviolet (UV, 280- 400 nm) radiation on the composition
of secondary metabolites of high nutritional value (pigments and flavonoids) in Lycopersicon esculentum (tomato) fruits. Tomato plants were grown during summer in the open field and two types of polytunnels, PT1 ( UV-A 1.45 mV cm-2, UV-B 3.84 μV cm-2, PAR 750 μmol m-2 s-1) and PT2 (UV-A 0.37 mV cm-2, UV-B 0.03 μV cm-2, PAR 760 μmol m-2 s-1) and fruits were taken in august. The contents of lycopene, β-carotene and flavonoids (quercetin and kaempferol) were determined by HPLC in the tomato exocarp and pulp. Regardless of UV radiation exposure, higher amounts of lycopene, flavonoids and β-carotene were measured in exocarp compared to the pulp. Accumulation of phenolics, in both exocarp and pulp was the highest in fruits collected in the field. Similarly, the concentration of epidermal flavonoids was the highest in the leaves of plants from the open field. These results support the protective functions of flavonoids as UV-screeners and antioxidants from
high PAR. Moreover, the content of lycopene was the highest in exocarp and β-carotene in the pulp of fruits exposed to full ambiental UV radiation doses, compared to fruits collected in the polytunells. The results implicate that the controlled exposure to solar UV radiation during crop growth may be used as a stimulator of biosynthesis of compounds with high antioxidative capacity thus improving the fruit quality and nutritional value.

abstract = "In this study we investigated the effects of ambient ultraviolet (UV, 280- 400 nm) radiation on the composition
of secondary metabolites of high nutritional value (pigments and flavonoids) in Lycopersicon esculentum (tomato) fruits. Tomato plants were grown during summer in the open field and two types of polytunnels, PT1 ( UV-A 1.45 mV cm-2, UV-B 3.84 μV cm-2, PAR 750 μmol m-2 s-1) and PT2 (UV-A 0.37 mV cm-2, UV-B 0.03 μV cm-2, PAR 760 μmol m-2 s-1) and fruits were taken in august. The contents of lycopene, β-carotene and flavonoids (quercetin and kaempferol) were determined by HPLC in the tomato exocarp and pulp. Regardless of UV radiation exposure, higher amounts of lycopene, flavonoids and β-carotene were measured in exocarp compared to the pulp. Accumulation of phenolics, in both exocarp and pulp was the highest in fruits collected in the field. Similarly, the concentration of epidermal flavonoids was the highest in the leaves of plants from the open field. These results support the protective functions of flavonoids as UV-screeners and antioxidants from
high PAR. Moreover, the content of lycopene was the highest in exocarp and β-carotene in the pulp of fruits exposed to full ambiental UV radiation doses, compared to fruits collected in the polytunells. The results implicate that the controlled exposure to solar UV radiation during crop growth may be used as a stimulator of biosynthesis of compounds with high antioxidative capacity thus improving the fruit quality and nutritional value.",

AB  - Rhinusa pilosa (Gyllenhaal) (Coleoptera, Curculionidae) induces galls in Linaria vulgaris Mill., Yellow or
common toadflax (Plantaginaceae). Gall is defined as atypical plant growth induced by host-specific organisms,
and represents larval chamber which provides food and protection during insect development. It has
been shown that gall formation is triggered by ovoipositional fluid (cecidogen). In order to determine which
cecidogen compounds may have bioactive properties, we performed comparative analysis of phenolics profiles
of cecidogen and stem extracts of L. vulgaris using UHPLC coupled with OrbiTrap mass analyzer. In addition,
we analyzed the effects of feeding, oviposition and early gall development on Class III peroxidase activity
(POD, EC 1.11.1.7) and phenolic content in the stems of L. vulgaris during seven days. Out of 55 phenolic
compounds identified in cecidogen and L. vulgaris stem, one unknown phenolic glycoside was found only in
cecidogen, which produced an MS2 base peak at 387 m/z, and 327 m/z and 267 m/z base peaks at MS3 and
MS4 fragmentation, respectively. Gall development during seven days was accompanied by decreased concentrations
of hydroxybenzoic, hydroxycinnamic acids and flavonoids and by slight lignin deposition. An oscillatory
induction of POD activity, with the first peak obtained 3 h after oviposition, was related to oxidative
burst during stem wounding and oviposition. Overall results suggested the importance of phenolics in stem
structural changes and regulation of plant metabolism induced by R. pilosa.
