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  - Acidovorax citrulli, the causal agent of bacterial fruit blotch (BFB), is an economically important pathogen of watermelon and related plant species worldwide. In the period 2014–2018, several outbreaks of BFB were observed in major watermelon production regions in Serbia. A total of 43 strains, isolated from symptomatic watermelon tissue, were analyzed by biochemical, pathogenic and molecular tests. Based on the phenotypic characteristics, PCR assay, and 16S rRNA gene sequence analysis, all strains were identified as A. citrulli. A multilocus sequence analysis of the four housekeeping (adk, gyrB, pilT and gltA) and three virulence genes (Aave_1548, avrRx01 and luxR) revealed that studied A. citrulli strains represent the homogeneous population and they clustered together with group II reference strain AAC00-1. Strain affiliation to group II was confirmed by PCR based on the putative type III secretion effector gene and by duplex PCR test. High homogeneity of studied strains was also confirmed by BOX-PCR. Differences were observed for two strains in their pathogenicity as well as susceptibility to copper compounds. Moreover, six major watermelon varieties grown in Serbia showed high sensitivity to the pathogen, while cross inoculation assay revealed that the strains were able to infect other species within the Cucurbitaceae family.
