AB  - The present study examined the effects of Candidatus Phytoplasma solani infection on antioxidative metabolism in leaves and roots of carrot (Daucus carota L.). Disease symptoms appeared at the end of June in the form of the chlorosis on some of the leaves, which became intensely red one week later, while the previously healthy leaves from the same branch becme chlorotic. A few days later, all leaves from the infected leaf branch were intensely red. Infected plants also had slower growth compared to the healthy ones with fewer leaf branches developed. The roots of infected plants were less developed, seared, or gummy with or without brown-colored root hair. The presence of the pathogen was detected by sequencing the 16S rRNA. National Center for Biotechnology Information (NCBI) BLAST analyses of the obtained sequence revealed 100% identity of tested strain with deposited Ca. Phytoplasma solani strains from various countries and hosts, all belonging to the "stolbur" group (16SrXII-A). Identity of 99.74% was found when the tested Serbian strain (MF503627) was compared with the reference stolbur strain STOL11 (AF248959). The oxidative damage of membranes in carrot cells was accompanied by a decrease in the content of photosynthetic pigments. Furthermore, for the determination of specific scavenging properties of the extracts, in vitro antioxidant assay was performed. In phytoplasma-infected carrot leaves, there was a greater reduction in the level of glutathione content (GSH); however; flavonoids and anthocyanidins seem to be responsible for the accompanied increased antioxidative capacity against hydroxyl radical and hydrogen peroxide.

AB  - Xanthomonas campestris pv. campestris (Xcc), the causal agent of black rot disease of cabbage (Brassica oleracea var. capitata L.), is one of the most important bacteria which affect proper cabbage growth, leading to head weight and quality losses and thereby drastically reducing its marketing value. The pathogen is genetically diverse, which is evident from the presence of eleven races worldwide and more than thirty combinations of allelic profiles. Therefore, this study aimed to determine the allelic profiles of Serbian cabbage Xcc strains obtained in 2014. The analysis was done on three selected Xcc strains whose DNA was first amplified using polymerase chain reaction (PCR) with four housekeeping genes - P-XdnaK, fyuA, gyrB, and rpoD, then sequenced, and the obtained sequences were finally used to determine allelic profiles. Allelic profiles were determined by comparison with 33 Xcc strains obtained from different hosts and regions, whose allelic profiles had been determined previously. A non-redundant database (NRDB) from the pubMLST was used for allelic profile determination and Phyloviz software for constructing a minimum spanning tree. The obtained allelic profile of all Serbian Xcc cabbage strains was 1, 3, 1, 1 for the P-X-dnaK, fyuA, gyrB and rpoD genes, respectively. This profile is assigned as sequence type 2 (ST2) and it coincides with a Portuguese B. oleracea Xcc strain, CPBF 213, originating from B. oleracea var. costata. No connection between sequence type (ST) and the host was detected.

AB  - Bacterial leaf spot caused by the plant pathogenic bacterium Pseudomonas syringae pv. coriandricola (Psc) was observed on carrot, parsnip, and parsley grown on a vegetable farm in the Vojvodina Province of Serbia. Nonfluorescent bacterial colonies were isolated from diseased leaves and characterized using different molecular techniques. Repetitive element PCR fingerprinting with five oligonucleotide primers (BOX, ERIC, GTG5, REP, and SERE) and the randomly amplified polymorphic DNA-PCR with the M13 primer revealed identical fingerprint patterns for all tested strains. Multilocus sequence analysis of four housekeeping genes (gapA, gltA, gyrB, and rpoD) showed a high degree (99.8 to 100%) of homology with sequences of Psc strains deposited in the Plant-Associated Microbes Database and NCBI database. The tested strains caused bacterial leaf spot symptoms on all three host plants. Host-strain specificity was not found in cross-pathogenicity tests, but the plant response (peroxidase induction and chlorophyll bleaching) was more pronounced in carrot and parsley than in parsnip.

AB  - Numerous scientific research studies all over the world have addressed the problem of agriculture in the 21st century as being particularly sensitive to climate change, which has caused phytopathogenic bacteria to spread. Therefore, there is a clear and urgent need to contain this kind of risk in agricultural production (both conventional and organic farming). The objective of this study was to determine the antibacterial activity of 30 essential oils (EOs) against three harmful plant pathogenic bacteria of agricultural importance, Erwinia amylovora, Xanthomonas campestris pv. campestris and Pseudomonas syringae pv. syringae. The study included in vitro testing, using an agar-diffusion assay. The EOs of Ceylon cinnamon (leaf and bark), oregano, clove bud and palmarosa revealed antibacterial activity against the test bacteria, and the maximum mean inhibition zone diameters of 35 mm was found against E. amylovora and X. campestris pv. campestris (highly sensitive reaction), while it was smaller in the case of P. syringae pv. syringae, from 18.25-26.25 mm (sensitive to very sensitive reaction). Maximum diameter of the zone of inhibition (35 mm) was obtained using basil and peppermint against E. amylovora, and rosemary, blue gum and camphor tree against X. campestris pv. campestris. Not a single EO inhibited P. syringae pv. syringae with the resulting total diameter zone of 35 mm, and this test bacteria was resultingly classified as the least susceptible bacterium of the three tested. EOs of lemongrass, aniseed, ylang ylang, silver fir, lemon, dwarf mountain pine, bay laurel and scots pine caused sensitive reaction of the tested bacteria. Peppermint, black cumin, Indian frankincense, bergamot orange, common juniper, bitter orange and neem produced variable reactions from total to weakly or no inhibition at all. Weakly activity was found in niaouli and Atlas cedar. Eastern red cedar, patchouli, Indian sandalwood and ginger caused no reaction of any of the test bacteria. The results offer a basis for further work based on in vivo testing for the purpose of developing ‘natural pesticides’ for control of phytopathogenic bacteria, thus giving a significant contribution to reducing yield losses in agriculture and sustainable development.
AB  - Brojna naučna istraživanja širom sveta potvrđuju da je poljoprivreda u 21. veku posebno osetljiva na klimatske promene koje su uzrok širenja fitopatogenih bakterija. Stoga je jasna hitna potreba za ublažavanjem ovog rizika u poljoprivrednoj proizvodnji (u konvencionalnoj i organskoj poljoprivredi). Cilj ovog rada je određivanje antibakterijske aktivnosti 30 etarskih ulja prema tri ekonomski značajne fitopatogene bakterije, Erwinia amylovora, Xanthomonas campestris pv. campestris i Pseudomonas syringae pv. syringae. Istraživanja su vršena u in vitro uslovima, korišćenjem agar-difuzne metode. Etarska ulja pravog cimeta (od lista i kore), origana, zatim karanfilića i palmaroze, su pokazala antibakterijsku aktivnost prema testiranim sojevima bakterija, ostvarujući zone inhibicije maksimum prečnika 35 mm dobijene u slučaju E. amylovora i X. campestris pv. campestris (visoko osetljiva reakcija), a u slučaju P. syringae pv. syringae manju, od 18.25-26.25 mm (osetljiva do vrlo osetljiva reakcija). Maksimalni prečnik inhibicione zone (35 mm) je takođe dobijen primenom ulja bosiljka i pitome nane prema E. amylovora i ruzmarina, eukaliptusa i ravensare prema X. campestris pv. campestris. Kod P. syringae pv. syringae ni u jednom slučaju primene ulja nije postignut maksimalan prečnik inhibicije od 35 mm, na osnovu čega je ova bakterija svrstana kao slabije osetljiva. Etarska ulja limun trave, anisa, ilang-ilanga, evropske jele, limuna, planinskog bora, lovora i belog bora su rezultirala osetljivom reakcijom testiranih sojeva bakterija. Pitoma nana, čurukot, tamjan, begramot, kleka, gorka pomorandža i nim su izazvali varijabilnu reakciju, od potpune inhibicije, do slabe ili čak i bez inhibicije. Slaba aktivnost je ostvarena kod niaoulija i atlaskog kedra. Sve tri testirane bakterije nisu pokazale reakciju prema virdžinijskoj kleki, pačuliju, sandalovini i đumbiru. Rezultati dobijeni u ovom radu daju osnovu za dalja istraživanja in vivo, sa svrhom razvoja 'prirodnih pesticida' koji se mogu primeniti za suzbijanje fitopatogenih bakterija, čime se daje značajan doprinos u smanjenju gubitaka prinosa u poljoprivredi i održivom razvoju.

Rezultati dobijeni u ovom radu daju osnovu za dalja istraživanja in vivo, sa svrhom razvoja 'prirodnih pesticida' koji se mogu primeniti za suzbijanje fitopatogenih bakterija, čime se daje značajan doprinos u smanjenju gubitaka prinosa u poljoprivredi i održivom razvoju.",

AB  - Unusual blight-like symptoms appeared on highbush blueberry plants in Serbia during August 2015 and infected plants showed browning and reddening of leaves, drying of foliage and brown discolouration of internal vascular stem tissues. The objective of this study was to isolate and confirm a causal agent of the disease. Five diseased blueberry plants (2-year-old), with visible brown discolouration in the wood, were collected for isolation on potato dextrose agar (PDA). Morphological analysis of the selected fungal isolates showed the presence of abundant black, round to oblong, or irregularly shaped microsclerotia immersed in the PDA. Dark, globose pycnidia formed on water agar with an initially hyaline, granular content and single-celled conidia, indicating the presence of plant pathogenic fungus Macrophomina phaseolina associated with symptomatic plant tissues. Pathogenicity was confirmed on potted blueberry plants based on the initial symptoms of leaves turning yellowish to brown at the leaf edges, followed by the defoliation of leaves of the inoculated stems. Discolouration of vascular tissues was also observed on transverse sections of inoculated stems. The pathogen M. phaseolina was confirmed using molecular analysis of the ITS1-5.8S-ITS2 region of rDNA and a part of the TEF-1 gene region. This is the first report of M. phaseolina causing a blight disease on highbush blueberry in Serbia. The study should help in elucidating disease symptomatology and provide information on the risk which this fungus could pose in blueberry production.
