AB  - Infections with phytoplasma present one of the most significant biotic stresses influencing
plant health, growth, and production. The phytoplasma ‘Candidatus Phytoplasma solani’ infects
a variety of plant species. This pathogen impacts the physiological and morphological characteristics of plants causing stunting, yellowing, leaf curling, and other symptoms that can lead to significant economic losses. The aim of this study was to determine biochemical changes in peony (Paeonia tenuifolia L.), mint (Mentha × piperita L.), and dill (Anethum graveolens L.) induced by ‘Ca. Phytoplasma solani’ in Serbia as well as to predict the impact of the biotic stress using artificial neural network (ANN) modeling. The phylogenetic position of the Serbian ‘Ca. Phytoplasma solani’ strains originated from the tested hosts using 16S rRNA (peony and carrot strains) and plsC (mint and dill strains) sequences indicated by their genetic homogeneity despite the host of origin. Biochemical parameters significantly differed in asymptomatic and symptomatic plants, except for total anthocyanidins contents in dill and the capacity of peony and mint extracts to neutralize superoxide anions and hydroxyl radicals, respectively. Principal Component Analysis (PCA) showed a correlation between different chemical parameters and revealed a clear separation among the samples. Based on the ANN performance, the optimal number of hidden neurons for the calculation of TS, RG, PAL, LP, NBT, •OH, TP, TT, Tflav, Tpro, Tant, DPPH, and Car was nine (using MLP 8-9-13), as it produced high r2 values (1.000 during the training period) and low SOS values. Developing an effective early warning system for the detection of plant diseases in different plant species is critical for improving crop yield and quality.

AB  - In August 2020, the unusual appearance of crown gall symptoms was observed on the
tobacco plants (hybrid PVH2310) grown in fields in the Golubinci (Srem district, Serbia) locality. The causal agent isolated from galls located on tobacco roots formed circular, convex, and glistening light blue colonies, and then dark to olive-green-colored bacterial colonies on a semi-selective D1 medium. Molecular analysis based on multiplex PCR and multi-locus sequence analysis (MLSA) using concatenated sequences of the atpD, dnaK, glnA, and rpoB genes as well as 16S rRNA identified Serbian tobacco isolates such as Agrobacterium tumefaciens (biovar 1). Two duplex PCR methods confirmed the presence of the virD2 and virC genes in tobacco isolates. Pathogenicity tests performed on carrot discs and squash fruits resulted in tumor/gall formation after 12 to 16 days post inoculation, respectively. Pathogenicity was also confirmed on tobacco plants, where isolates caused tumor development 21−25 days after inoculation. API 50 CH generated results regarding the biochemical features of the Serbian tobacco isolates. As A. tumefaciens (biovar 1) as a cause of tobacco crown gall has previously been documented solely in Japan, there is presently no data on its wider occurrence. Therefore, this first detailed investigation of A. tumefaciens isolated from naturally infected tobacco in Serbia will contribute to a better understanding of it at the global level.

AB  - Bakterija Xanthomonas campestris pv. campestris (Xcc) je sveprisutna kao
prouzrokovač crne truleži biljaka iz familije kupusnjača, pre svega kupusa, a zatim i karfiola, brokolija, kelja, prokelja, kelerabe, raštana, ali i uljane repice, slačice, rotkvice, hrena, kres salate, određenih sorti model biljke Arabidopsis thaliana i nekih korovskih vrsta i ukrasnih biljaka. Negativnim uticajem na rast i razvoj domaćina, a time i veličinu i kvalitet prinosa, dovodi do značajnih ekonomskih gubitaka. Beležene štete izazvane ovim patogenom procenjuju se na više od 50% na kupusu, odnosno 50 – 70% na karfiolu. U Srbiji se Xcc nakon
prve pojave na kelju 1960-ih, redovno javlja na svim gajenim kupusnjačama. S obzirom na obim i tradiciju gajenja različitih kupusnjača, ova bakterija je najznačajniji patogen kupusa. Dosadašnje genetičke analize prisutnih populacija Xcc poreklom sa kupusa u Srbiji nisu ukazale na postojanje diverziteta, bez obzira na sortu, godinu ili lokalitet sa kog su izolovane. Cilj ovog rada je da se izoluju i genetički okarakterišu novije populacije bakterije Xcc poreklom
sa kupusa. Tokom avgusta i septembra 2021. godine, listovi kupusa sa simptomima crne truleži, sakupljeni su sa četiri parcele u Vojvodini, dve u lokalitetu Futog (sorta Futoški obe parcele) i dve u Begeču [sorta Futoški i crveni kupus (nepoznata sorta)]. Izolacija prouzrokovača bolesti vršena je na podlogu od kvaščevog ekstrakta, dekstroze i kalcijum karbonata (engl. Yeast extract dextrose-calcium carbonate agar, YDC). Nakon tri dana inkubacije na 26 °C, formirane su svetlo žute, sjajne, konveksne i mukoidne bakterijske kolonije. Četiri reprezentativna izolata (sa svake parcele po jedan, pod šiframa Xc221, Xc321, Xc421, Xc521, redom) su odabrana i analizirana na osnovu sekvenci konzervativnog gena gyrB. Patogenost odabranih izolata je dokazana infiltracijom bakterijske suspenzije u listove kupusa. Lančana reakcija polimeraze (PCR) je korišćena za umnožavanje DNK izolata, očekivane dužine 865 bp, po sledećem programu: inicijalna denaturacija 94 °C 3 min, 30 cikusa denaturacije 94 °C 30 sec, hibridizacije 54 °C 30 sec i elongacije 72 °C 1 min, i finalna elongacija 72 °C 10 min. Amplifikovani produkti su sekvencirani (Eurofins Genomics), a kvalitet dobijenih sekvenci manuelno pregledan. Filogenetsko „Neighbour-joining” stablo je konstruisano primenom MEGA7 programa, sa izolatima iz ove studije i sojevima populacija izolovanih sa kupusa tokom prethodnih godina na području Srbije. Dobijeni rezultati su pokazali genetičku homogenost novijih populacija Xcc sa prethodno opisanim i prisutnim u Srbiji, bez obzira na godinu izolacije, lokalitet ili sortu. Prema dostupnim podacima, dobijeni rezultati ukazuju na održavanje iste populacije ove bakterije tokom poslednje decenije.
