AB  - During May 2016, severe blight symptoms were observed in several raspberry and blackberry fields in Serbia. In total, 22 strains were isolated: 16 from symptomatic raspberry shoots, 2 from asymptomatic raspberry leaves, and 4 from symptomatic blackberry shoots. Additionally, eight raspberry strains, isolated earlier from two similar outbreaks, were included in the study. Pathogenicity of the strains was confirmed on detached raspberry and blackberry shoots by reproducing the symptoms of natural infection. The strains were Gram-negative, fluorescent on King’s medium B, ice nucleation positive, and utilized glucose oxidatively. All strains were levan positive, oxidase negative, nonpectolytic, arginine dihydrolase negative, and induced hypersensitivity in tobacco leaves (LOPAT + −−− +, Pseudomonas group Ia). Furthermore, all strains liquefied gelatin and hydrolyzed aesculin but did not show tyrosinase activity or utilize tartrate (GATTa + + − −). Tentative identification using morphology, LOPAT, GATTa, and ice-nucleating ability tests suggested that isolated strains belong to Pseudomonas syringae. The syrB gene associated with syringomycin production was detected in all strains. DNA fingerprints with REP, ERIC, and BOX primers generated identical profiles for 29 strains, except for strain KBI 222, which showed a unique genomic fingerprint. In all, 9 of 10 selected strains exhibited identical sequences of four housekeeping genes: gyrB, rpoD, gapA, and gltA. Five nucleotide polymorphisms were found in strain KBI 222 at the rpoD gene locus only. In the phylogenetic tree based on a concatenated sequence of all four housekeeping genes, strains clustered within phylogroup 2 (i.e., genomospecies 1) of the P. syringae species complex, with pathotype strains of P. syringae pv. aceris and P. syringae pv. solidagae as their closest relatives. There was no correlation between genotype and geographic origin, particular outbreak, host, or cultivar.

AB  - Glavni cilj istraživanja fitopatogenih bakterija je njihovo bolje poznavanje i razvoj
efikasne strategije zaštite. Klimatske promene, globalna distribucija reproduktivnog biljnog
materijala, evolucija poljoprivredne prakse i povećana zabrinutost za životnu sredinu,
zahtevaju nove pristupe kontroli bakterioza biljaka. Stoga je mogućnost primene prirodnih,
zdravstveno i ekološki prihvatljivih mehanizama kontrole fitopatogenih bakterija, izazvala
povećano interesovanje biljnih bakteriologa. Biološka kontrola, kao novi oslonac integrisanih
strategija kontrole biljnih bolesti, mogla bi doprineti prihvatljivoj efikasnosti i održivosti
trenutnih mera zaštite. Strategije biološke kontrole se uglavnom zasnivaju na sprečavanjju
nastanka infekcije, smanjenju učestalosti bakterioza biljaka bilo selektovanom ili
indukovanom otpornošću, konkurencijom, antibiozom ili ometanjem životnog ciklusa
patogena. Većina poznatih bioloških agenasa pripada rodovima Bacillus, Lactobacillus,
Erwinia, Pantoea, Streptomyces, Bdellovibrio, fluorescentnim Pseudomonas spp.,
bakteriofagima i protozoama. Neki takođe uključuju avirulentne oblike patogenih sojeva. Kao
jedna od ciljanih tačaka, osim samih bakterijskih ćelija, nameće se ometanje formiranja
biofilma ili manipulacija fizioloških procesa bakterije upotrebom signalnih molekula. Novija
istraživanja takođe ukazuju da bi se značajan napredak u ispoljavanju konkurentnosti i
sposobnosti bioloških agensa u proizvodnji antimikrobnih metabolita ili izazivanju otpornosti
biljaka mogao postići boljim razumevanjem prirode njihovog preživljavanja i procesa
interakcije sa fitopatogenim bakterijama, ali i sa drugim činiocima mikrobioma i životnom
sredinom uopšte. U većini slučajeva, efikasna primena takvih jedinjenja i zadovoljavajući
efekat njihove biološke aktivnosti zahtevaju razvoj posebnih tehnika ili kombinaciju više od
jednog agensa. Međutim, uprkos nedavno povećanom broju i raznolikosti istraživačkih
programa, mora se priznati da su broj i dostupnost komercijalnih biobaktericida i dalje
ograničeni.

AB  - During spring and summer of 2008, 101 bacterial strains was isolated from the diseased pepper leaves collected from different pepper growing areas in the Republic of Serbia. The aim of this research was to characterize the isolated strains and determine their taxonomic position according to the most recent nomenclature. Pathogenic, biochemical and physiological characteristics of isolated bacteria were tested using standard bacteriological tests. The pathogen races were determined according to the reaction of differential varieties of Early Calwonder (ECW), their isogenic lines (ECW-10R, ECW-20R, ECW-30R) and Capsicum pubescens. The sensitivity of strains to bactericides was studied in vitro by culturing bacteria on sucrose pepton agar (SPA) plates, amended with filter-sterilized aqueous solution of streptomycin and kasugamycin (50, 100, 200 ppm) or copper-sulphate (100, 200 ppm). Based on pathogenic, biochemical and physiological characteristics, the investigated strains belonged to Xanthomonas euvesicatoria. The reaction of pepper differential varieties indicated that these strains belonged to pepper races P1, P3, P7, P8. Streptomycin resistant strains were not detected, but 6 strains were resistant to kasugamycin (50 ppm) and 13 strains to copper-sulphate (200 ppm), indicating bacterial resistance development.
