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.

AB  - In Montenegro, stone fruit species are grown on intensive and semi-intensive commercial plantations. However, almond production is mainly organized on family gardens and for household consumption. During two seasons (2017–2018), we surveyed apricot, peach, nectarine, sweet cherry, Japanese plum, and almond orchards for the presence of bacterial diseases at different geographical locations in Montenegro. From leaf, petiole and fruit lesions, branch or twig cankers, and necrotizing buds, a total of 29 isolates were obtained and subjected to identification based on their morphological, pathogenic, biochemical, and molecular characteristics. Pathogenicity of the isolates was confirmed by reproducing the symptoms on leaves, fruits, and twigs of the corresponding host plants. The biochemical tests indicated that the isolates belong to Pseudomonas syringae. However, isolates’ characterization showed variation in their phenotypic and molecular features. The presence of the syrB gene and ice nucleation activity grouped most of the isolates within pathovar syringae. The results of rep-PCR using the BOX primer revealed high genetic diversity of isolates. Multilocus sequence analysis (MLSA), using four housekeeping genes, showed that 27 isolates belong to the genomic species 1, P. syringae sensu stricto, corresponding to P. syringae phylogroup 2. However, isolates from the same phylogroup 2 did not form a monophyletic group. One strain isolated from apricot was most distinct and similar to members of genomic species 2, phylogroup 3. All tested isolates showed significant levels of resistance to copper sulfate and high level of sensitivity to streptomycin sulfate in vitro.

AB  - Watermelon (Citrullus lanatus) and squash (Cucurbita pepo) are traditionally grown in northern Serbia, in the province of Vojvodina. Most of the cucurbit cultivars grown in Serbia originate from imported seed. In July 2013, round, water-soaked lesions were observed on the fruits on sporadic squash plants grown in two fields of the breeder variety trials in Bački Petrovac. Affected tissue was light brown, slightly sunken, soft, and macerated. From symptomatic plants (cultivar GL Maxima), showing 30% symptom intensity, a uniform population of bacterial colonies was isolated, and one strain was chosen for the collection. In August of the following season, infection of the vine was observed on watermelon plants (cultivar unknown) grown in a commercial field in Čelarevo. Soft rot brownish lesions developed on infected stems, resulting in collapse and wilting of entire vines. The number of plants affected with symptoms was less than 10%. From the colonies isolated from the diseased tissue, two bacterial strains were purified and stored in the collection. Being pectolytic and isolated from cucurbits, the squash strain and two watermelon strains were subjected to further characterization. The strains developed white-gray, nonmucoid, round colonies with irregular margins on nutrient agar medium. They were gram and oxidase negative, tobacco HR and catalase positive, facultative anaerobes, nonfluorescent, caused soft rot on potato tuber slices, grew at 37°C, and reduced nitrate. They neither utilized arginine nor produced acid from sorbitol and inositol, showing characteristics of Pectobacterium species (De Boer and Kelman 2001). The PCR assay was carried out using primers BR1f/L1r (Duarte et al. 2004), specific for Pectobacterium carotovorum subsp. brasiliense (Pcb). A specific fragment of 322 bp was amplified for all three strains tested. The 16S rDNA sequence analysis (GenBank nos. MH031784, MH031785, and MH031786) showed 99% identity to the sequences of Pcb isolated from cucumber (CP020350), pepper (KX377597), and cabbage (KY021040) in China and potato in Japan (LC146476). The recA (MK911735, MK911736, and MK911737) and gapA (MK911738, MK911739, and MK911740) sequence analysis of three strains showed the highest nucleotide identity (100 to 98.35% and 99.42 to 98.08%, respectively) with Pcb previously deposited in NCBI GenBank database. Pathogenicity of the strains was tested on 2-week-old watermelon (cv. Rosa) and melon (cv. Sezam) seedlings, grown in a commercial potting mix in a greenhouse, as well as on mature zucchini fruits. Three seedlings per strain were inoculated by spraying with bacterial suspension (approx. 1 × 108 CFU/ml) using a handheld sprayer. Inoculated plants were incubated under plastic bags for 24 h and afterward maintained in a greenhouse at 28 ± 2°C. Two days after inoculation, water-soaked lesions developed on cotyledons of the watermelon and melon plants. No symptoms were observed on control plants sprayed with water. Three zucchini fruits were inoculated by pricking with a syringe and hypodermic needle and leaving a droplet of bacterial suspension (approx. 1 × 107 CFU/ml) at the point of inoculation. Inoculated fruits were placed on wet filter paper in a sealed plastic container at 28 ± 2°C. Treatment with sterile distilled water was used as a negative control. Discoloration of the tissue and soft rot spreading from the inoculation point developed within 48 h from inoculation. No symptoms developed on the control fruits. To complete Koch’s postulates, bacteria were reisolated from the inoculated plant and fruit tissue and were identified as Pcb by PCR assay (Duarte et al. 2004). This is the first report of Pcb causing soft rot of squash and watermelon in Serbia. The origin of the pathogen remained unknown. It might have been present in Serbia for some time but misidentified in previous studies that could not discriminate this subspecies or recently introduced by infected seed.

AB  - Bacterial spot caused by Xanthomonas euvesicatoria is one of the most devastating pepper diseases in Serbia. Questionable seed quality, climatic conditions, and frequent irrigation during summer favour the disease occurrence and spread. The available management practices do not provide adequate disease control. Therefore, development of alternative and more sustainable disease management strategies is needed. Integration of classical and biological treatments could be an effective, environmentally safe option for reducing pepper bacterial spot severity. In order to develop an efficient integrated disease management program, we studied efficacy of biocontrol agents (bacteriophage strain KФ1 and two strains of Bacillus subtilis AAac and QST 713), systemic acquired resistance (SAR) inducer (acibenzolar-S-methyl - ASM), a commercial microbial fertilizer (Slavol), copper based compounds (copper hydroxide and copper oxychloride) in combination with or without mancozeb, and antibiotics (streptomycin sulphate and kasugamycin). They were applied as single treatments in two separate field experiments. Based on the single treatment efficacy, various combinations of the treatments were chosen for further testing in three separate field experiments. Additionally, we evaluated potential negative effect of ASM on pepper growth and yield in the growth chamber experiment. All the tested single treatments significantly reduced disease severity compared to the inoculated control (IC), except microbiological fertilizer and the antagonistic strain AAac. Integration of copper hydroxide, ASM and bacteriophages was the most efficient treatment, reducing the disease intensity by 96–98%. The results indicated that this combination may be an adequate alternative program for control of pepper bacterial spot.

AB  - Xanthomonas euvesicatoria phage K Phi 1, a member of Myoviridae family, was isolated from the rhizosphere of pepper plants showing symptoms of bacterial spot. The phage strain expressed antibacterial activity to all X. euvesicatoria strains tested and did not lyse other Xanthomonas spp., nor other less related bacterial species. The genome of K Phi D1 is double-stranded DNA of 46.077 bp including 66 open reading frames and an average GC content of 62.9%, representing the first complete genome sequence published for a phage infecting xanthomonads associated with pepper or tomato. The highest genome similarity was observed between phage K Phi 1 and the Xanthomonas oryzae pv. oryzae specific phage OP2. On the other hand, when compared with other members of the genus Bcep78virus, the genome similarity was lower. Forty-four (67%) predicted K Phi 1 proteins shared homology with Xanthomonas phage OP2, while 20 genes (30%) were unique to K Phi 1. Phage K Phi 1, which is chloroform resistant and stable in different media and in the pH range 5-11, showed a high titer storage ability for at least 2 years at +4 degrees C. Copper-hydroxide and copper-oxychloride reduced phage activity proportionally to the used concentrations and the exposure time. UV light was detrimental to the phage strain, but skim milk plus sucrose formulation extended its survival in vitro. The phages survived for at least 7 days on the surface of pepper leaves in the greenhouse, showing the ability to persist on the plant tissue without the presence of the host bacterium. Results of three repeated experiments showed that foliar applications of the unformulated K Phi 1 phage suspension effectively controlled pepper bacterial spot compared to the standard treatment and the untreated control. The integration of the phage K Phi 1 and copper-hydroxide treatments resulted in an increased efficacy compared to the copper-hydroxide alone.

AB  - Rhizobium rhizogenes, may seriously impact production in nurseries and vineyards worldwide. Although rapid and efficient detection and identification of tumorigenic bacteria is facilitated by PCR-based methods, high genetic diversity of these pathogens may hinder use of these methods in the disease diagnosis. Therefore, reliability of 11 primer pairs targeting fragments located on Ti plasmid or chromosomal DNA was tested on extensive collection of All. vitis, A. tumefaciens complex and R. rhizogenes strains isolated from grapevine throughout the world. Only primers VCF3/VCR3 targeting virC gene located on Ti plasmid clearly and accurately identified all tested tumorigenic strains associated with grapevine crown gall. Moreover, this primer pair coupled with primers specific for chromosomal pehA gene (PGF/PGR) in duplex PCR, may be recommended as the method of choice for routine preliminary identification of tumorigenic strains and differentiation of All.

AB  - Continuous use of copper-based treatments and antibiotics in pear and apple protection programs may result in appearance of copper or antibiotic resistant strains of Erwinia amylovora. In order to determine the potential occurrence of copper or/and antibiotic resistance in Serbia we studied in vitro effect of different concentrations of copper sulfate, streptomycin and kasugamycin on development and growth of 40 E. amylovora strains originating from this region. Filter sterilized solution of the bactericides was added to the NA medium after sterilization to a final concentration of 100 and 200 ppm, respectively, followed by spot inoculation of each strain on the medium. None of the strains developed on NA amended with 100 or 200 ppm of streptomycin or kasugamycin. Our study showed that, despite the potential exposure to the antibiotics, E amylovora strains from Serbia did not develop resistance to streptomycin or kasugamycin. On the other hand, all strains had normal growth on NA amended with 100 ppm of copper sulfate indicating certain level of resistance to copper ions. At 200 ppm, 28 strains formed colonies of normal size and appearance, while 12 strains had smaller colonies with reduced growth. This might be due to the extensive and frequent use of copper-based compounds to control fire blight in Serbia.

AB  - During the summer of 2014, watermelon producers in the north of Serbia (Srem district), observed the occurrence of irregularly shaped, water-soaked lesions on mature watermelon fruits indicating possible bacterial nature of the disease. Bacteria were isolated from symptomatic samples and identified as Acidovorax citrulli, previously described as a causal agent of bacterial fruit blotch. In the past few years, this pathogen caused considerable damage to the watermelon industry of the United States where, in some commercial production sectors, the loss of marketable fruit reached 90%. In Serbia, it is considered a quarantine pathogen and was not recorded until 2014.

Izolacijom i identifikacijom patogena, utvrđeno je prisustvo bakterije Acidovorax citrulli, prouzrokovača bakteriozne mrljavosti plodova lubenice. Ova vrsta je u skorije vreme dosta dobila na značaju, posebno zbog gubitaka u proizvodnji koji su u pojedinim oblastima Sjedinjenih Američkih Država (SAD) dostizali i 90% od ukupnog prinosa. U Srbiji A. citrulli ima karantinski status i nalazi se na A1 listi Evropske i mediteranske organizacije za zaštitu bilja (EPPO).

AB  - During the last 3 years, crown gall disease was observed in some young raspberry plantations throughout Serbia, causing considerable economic losses. Based on biochemical and physiological tests, PCR targeting the 23S rRNA gene, and 16S rRNA and recA gene sequence analysis, at least two different species were identified as causal agents of disease. Out of 14 strains isolated from raspberry tumors, 12 were identified as tumorigenic Rhizobium rhizogenes, one belonged to Agrobacterium tumefaciens genomic species G8, while the remaining strain formed a separate phylogenetic lineage within A. tumefaciens species complex, different from all known genomic species. All strains investigated harbored nopaline-type of Ti plasmid and showed identical pathogenic properties by inoculating several test plants. However, they were divided into two genetic groups based on PCR-RFLP analysis of Ti plasmid virA-virB2 region. Furthermore, total of nine unique ERIC-PCR profiles were identified among the strains studied. Although strains of R. rhizogenes exhibited similar ERIC-PCR profiles, they were differentiated into six distinct genetic groups. Based on the fact that some genetic groups were composed of strains originating from different geographic areas, it can be assumed that they have a common origin and were probably disseminated by movement of infected plant material.

AB  - In this study, three bacterial DNA extraction procedures were compared prior to real-time PCR. Healthy pear leaves and twigs were crushed in antioxidant maceration buffer and spiked with Erwinia amylovora to final concentrations from 2.1 x 10(6) to 2.1 x 10(1) cells ml(-1). Bacterial DNA was extracted from aliquots of spiked crude extracts using (i) isopropanol, (ii) REDExtract-N-Amp (TM) Plant PCR kit, and (iii) Taylor's modified DNA purification procedure. The ams region of the chromosomal DNA was selected as target for the real-time PCR. In this study, the REDExtract-N-Amp (TM) and Taylor's modified DNA extraction procedure were most successful in removing PCR inhibitors, leading to detection of 2.1x10(2) E. amylovora CFU/ml. At this concentration, pathogen can be efficiently detected in less than 5 h in spite of inhibitors and plant DNA reducing sensitivity of the reaction. These two methods increased amplification efficiency in real-time PCR compared to a simple isopropanol DNA extraction procedure from plant tissues, where the lowest detected concentration was 2.1 x 10(4) CFU/ml. In our research, real-time PCR has proven to be very sensitive method for detection of E. amylovora in plant material. It was 100 times more sensitive compared to other conventional PCR procedures.

Healthy pear leaves and twigs were crushed in antioxidant maceration buffer and spiked with Erwinia amylovora to final concentrations from 2.1 x 10(6) to 2.1 x 10(1) cells ml(-1). Bacterial DNA was extracted from aliquots of spiked crude extracts using (i) isopropanol, (ii) REDExtract-N-Amp (TM) Plant PCR kit, and (iii) Taylor's modified DNA purification procedure. The ams region of the chromosomal DNA was selected as target for the real-time PCR. In this study, the REDExtract-N-Amp (TM) and Taylor's modified DNA extraction procedure were most successful in removing PCR inhibitors, leading to detection of 2.1x10(2) E. amylovora CFU/ml. At this concentration, pathogen can be efficiently detected in less than 5 h in spite of inhibitors and plant DNA reducing sensitivity of the reaction. These two methods increased amplification efficiency in real-time PCR compared to a simple isopropanol DNA extraction procedure from plant tissues, where the lowest detected concentration was 2.1 x 10(4) CFU/ml. In our research, real-time PCR has proven to be very sensitive method for detection of E. amylovora in plant material. It was 100 times more sensitive compared to other conventional PCR procedures.",

AB  - In search for an alternative to chemical control of fire blight, we isolated seven bacteriophages specific to E. amylovora. Three phages were isolated from water, three from symptomless pear leaves and one from apple leaves with characteristic fire blight symptoms. Host-range studies showed that the phages differed in the ability to lyse 40 strains of E. amylovora isolated in Serbia. Based on its lytic activity, phage Phi Ea2 was chosen for further study of biological control potential in pear and apple blossom bioassays. A phage suspension of 10(8) PFU/ml was applied on blossoms either 2 h before, 2 h after or at the same time of inoculation. In three fully replicated bioassay experiments, application of host-specific phages 2 h before inoculation and at the time of inoculation significantly reduced fire blight symptom development compared to untreated control. However, disease reduction was not significant when phages were applied 2 h after inoculation.

AB  - Serious outbreaks of grapevine crown gall disease were observed in major Serbian viticultural regions during the last five years. Tumorigenic Agrobacterium vitis was identified as a causal agent by using conventional bacteriological and molecular tests. The 36 studied strains of A. vitis showed homogeneous biochemical and physiological characteristics, but were heterogeneous in their pathogenic properties, especially on tomato and sunflower. Furthermore, genetic differences related to chromosomal and plasmid DNA were observed. The Ti plasmid of 35 strains was classified as the octopine/cucumopine (O/C) type, whereas one was classified as the vitopine (V) type. The O/C strains were further divided into O/C-1 and O/C-2 groups based on PCR analysis. Moreover, the sequence analysis of the 16S-23S rRNA ITS region provided robust and precise delineation of studied strains. Although a high level of genetic diversity in A. vitis strains from Serbia was revealed by using this approach, their genotypic relatedness with the strains from other countries suggested their common origin. Also, association between the chromosomal and plasmid DNA was determined for some phylogenetic groups and clusters.

AB  - Crown gall, caused by tumorigenic strains of Agrobacterium spp., is considered one of the most important diseases in stone fruit nurseries throughout the world. Since the crown gall disease has not been studied extensively in Serbia for more than 30 years, the objective of this study was to isolate, identify and characterize the bacterium associated with crown gall symptoms on one-year-old apricot trees. Samples were collected from a nursery in central Serbia and subjected to laboratory analysis. Bacteria were isolated from tumour tissue on yeast mannitol agar (YMA) and six gram-negative isolates were selected for further study. PCR assay using primers specific for virD2, virC, ipt and tms2 pathogenicity-associated plasmid genes revealed that isolates harbour Ti plasmids. All studied strains carrying Ti plasmids were classified as nopaline-type based on further molecular analysis. Using a multiplex PCR assay, targeting 23S rRNA gene sequences, and physiological and biochemical tests, five strains were assigned as A. rhizogenes/biovar 2 and the remaining one as A. tumefaciens/biovar 1. Identity of the strains was confirmed by sequence analysis of the 16S rRNA gene. In pathogenicity assay, all six strains caused tumour formation on inoculated carrot root discs, young tomato and sunflower plants.
