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  - Bacterial fruit blotch and seedling blight, caused by Acidovorax citrulli, is one of the most destructive diseases of melon and watermelon in many countries. Pathogen-free seed and cultural practices are major pillars of the disease control. However, use of bacteriophages as natural biocontrol agents might also contribute to the disease management. Therefore, we isolated 12 bacteriophages specific to A. citrulli, from phyllosphere and rhizosphere of diseased watermelon plants. The phage strains were characterized based on their host range, plaque and virion morphology, thermal inactivation point, adsorption rate, one step growth curve, restriction fragment length polymorphism (RFLP), and genomic analysis. Transmission electron microscopy of three phage strains indicated that they belong to the order Caudovirales, family Siphoviridae. All phages lysed 30 out of 32 tested A. citrulli strains isolated in Serbia, and did not lyse other less related bacterial species. They produced clear plaques, 2 mm in diameter, on bacterial lawns of different A. citrulli strains after 24 h of incubation. The thermal inactivation point was 66 or 67°C. They were stable at pH 5–9, but were sensitive to chloroform and inactivated in either 5 or 10 min exposure to ultraviolet (UV) light. RFLP analysis using EcoRI, BsmI and BamHI enzymes did not show genetic differences among the tested phages. Adsorption rate and one step growth curve were determined for the Acidovorax phage ACF1. Draft genome sequence of the ACF1 phage was 59.377 bp in size, with guanine-cytosine (GC) content 64.5%, including 89 open reading frames. This phage shared a very high genomic identity with Acidovorax phage ACPWH, isolated in South Korea. Evaluation of systemic nature of ACF1 strain showed that it can be absorbed by roots and translocated to upper parts of watermelon plants where it survived up to 10 days.

AB  - Xanthomonads, members of the family Xanthomonadaceae, are economically important plant pathogenic bacteria responsible for infections of over 400 plant species. Bacteriophage-based biopesticides can provide an environmentally friendly, effective solution to control these bacteria. Bacteriophage-based biocontrol has important advantages over chemical pesticides, and treatment with these biopesticides is a minor intervention into the microflora. However, bacteriophages’ agricultural application has limitations rooted in these viruses’ biological properties as active sub-stances. These disadvantageous features, together with the complicated registration process of bacteriophage-based biopesticides, means that there are few products available on the market. This review summarizes our knowledge of the Xanthomonas-host plant and bacteriophage-host bacterium interaction’s possible influence on bacteriophage-based biocontrol strategies and provides examples of greenhouse and field trials and products readily available in the EU and the USA. It also details the most important advantages and limitations of the agricultural application of bacteriophages. This paper also investigates the legal background and industrial property right issues of bacteriophage-based biopesticides. When appropriately applied, bacteriophages can provide a promising tool against xanthomonads, a possibility that is untapped. Information presented in this review aims to explore the potential of bacteriophage-based biopesticides in the control of xanthomonads in the future.

AB  - Three PCR methods, referred in this study as,conventional" "nested" and,chromosomal" PCR and suggested for routine detection of Erwinia amylovora in pure culture and plant material, were evaluated according to their specificity and sensitivity. Specificity of PCR methods was analyzed by using 42 strains of E. amylovora, originating from different locations and plant species, with diverse PFGE profiles, representing distant populations of the pathogen. Sensitivity of PCR protocols in pure culture was studied by using nine different concentrations of E. amylovora in sterile ultrapure water as a template in PCR reactions. In order to study inhibitory effect of plant DNA and other inhibitors on sensitivity of the three PCR methods bacterial dilutions were mixed with plant macerate of pear, apple and quince prior to the PCR reaction. In specificity assays, tested PCR protocols were able to detect all E. amylovora strains regardless of the host of the strain, its origin or PFGE group, indicating primer specificity. On the other hand, sensitivity among tested methods varied, depending on bacterial concentration and selected plant material used in the PCR. When working with pure cultures nested PCR showed the greatest sensitivity by detecting 1.9 bacterial cells per PCR reaction, followed by detection limit of 9.5 cells per PCR reaction with conventional PCR and 1.9.105 cells/PCR reaction with chromosomal PCR. In spiked samples plant inhibitors either did not affect or they decreased the sensitivity of the PCR reaction, depending on the protocol and/or type of plant macerate. In our experiments, inhibitors from pear and quince macerates did not affect sensitivity of nested PCR, while apple macerate reduced its sensitivity by a factor of 10. Conventional PCR protocol was able to detect 95 cells/PCR reaction in pear and apple macerate, but only 9.5.103 cells/PCR in quince macerate. Greatest decrease in sensitivity of the PCR method was observed in spiked samples with chromosomal PCR since bacterial DNA was not detected in each of the spiked samples. Our research shows that all three PCR protocols are specific for detection of E. amylovora, but nested PCR proved to be most sensitive when working with pure cultures and plant material.

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 K Phi 1 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  - The diversity of 30 Erwinia amylovora strains, isolated from quince, pear and apple trees on 14 localities in Serbia, was studied using bacteriological and molecular methods. In pathogenicity tests, all strains caused necrosis and oozing of bacterial exudate on inoculated immature pear, cherry and plum fruits, and induced hypersensitive reaction in tobacco leaves. The studied strains were Gram and oxidase negative, non-fluorescent, levan and catalase positive and facultatively anaerobic. The strains did not reduce nitrates, but utilized citrate and produced acid from sorbitol, hydrolyzed gelatine, produced reducing substances from sucrose and grew in the presence of 5% NaCl, but not at 36oC. Identity of the strains was confirmed by conventional and nested PCR methods. Rep-PCR with REP, ERIC and BOX primers resulted in amplification of several DNA fragments respectively, but showed no variation within the strains. However, different genetic profiles were obtained with RAPD-PCR by using six primers which enabled differentiation of the strains into four groups. Genetic differences between the studied strains did not correlate with the host plants, geographical origin or year of isolation.

AB  - Bacterial spot of pepper and tomato caused by Xanthomonas species, is one of the widespread and economically most important diseases of pepper and tomato. Due to the lack of resistant pepper and tomato genotypes, the emergence of new races of bacteria, and strains resistant to copper compounds, questionable seed quality and limited control practices, thesebacteria are limiting pepper production in Serbia. On tomato plants, under favourable weather conditions for disease development, these bacteria can cause major damage reflected in overall yield as well as in fruit quality. The protection of pepper and tomato, based on chemical methods such as use of copper-based compounds in combination with ethylene-bis-dithiocarbamates, do not provide a satisfactory disease control. Use of antibiotics in plant protection is not permitted in the EU as well as in Serbia. However, results of many authors show that satisfactory control of bacterial spot can be achieved by integrating positive effect of chemical treatments (copper compounds, systemic resistance activators) and various biological methods (antagonists, bacteriophages). However, nature of biological agents, as well as the specific mechanism of action of the systemic resistance activators, require careful optimization of the time and number of treatments in order to achieve maximum efficiency.

AB  - Bacterial spot of pepper and tomato regularly causes losses in production in Serbia. According to the new systematization, four Xanthomonas species have been reported as causal agents of leaf spots of pepper and tomato: X. euvesicatoria, X. vesicatoria, X. perforans and X. gardneri.

AB  - Bacterial diseases are very common in tomato and pepper crops, especially under favourable weather conditions. One of the economically most important pathogens that affect tomato production worldwide is Ralstonia solanacearum, causal agent of bacterial wilt of tomato. The pathogen survives in soil and water. It colonizes xylem, clogs the vascular tissue preventing water movement throughout the stem, causing colapse of the infected plants. In addition, wilting of tomato and pepper can be caused by Candidatus Phytoplasma solani (Stolbur Phytoplasma). Main sources of infection with this pathogen are wild plants from where it is further transmitted by feeding of leafhopper vectors. The aim of this paper is to point to distribution and economic importance of those diseases, as well as characteristics of the pathogens. Information about symptoms and epidemiology of the disease are important for an accurate disease diagnosis and pathogen identification, which contributes to the timely and successful protection strategy.
AB  - Oboljenja bakteriozne prirode veoma su česta u usevima paradajza i paprike, posebno kada vremenski uslovi pogoduju nastanku i širenju infekcije. Među ekonomski najznačajnijim bakterijama koje ugrožavaju proizvodnju paradajza u svetu, izdvaja se prouzrokovač bakteriozne uvelosti paradajza Ralstonia solanacearum. Patogen se dugo održava u zemljištu i vodi. Naseljava ksilem biljaka onemogućavajući protok vode, usled čega dolazi do pojave uvelosti. Osim ovog patogena, simptome uvelosti paradajza i paprike može takođe prouzrokovati Candidatus Phytoplasma solani (Stolbur fitoplazma). Ovo oboljenje prenosi se cikadama, dok su glavni izvori infekcije korovske biljke. Cilj ovog rada je da se prikaže rasprostranjenost i ekonomski značaj navedenih oboljenja paradajza i paprike, kao i osnovne karakteristike njihovih prouzrokovača. Poznavanje simptomatologije i epidemiologije oboljenja je od posebnog značaja za pravilnu dijagnozu oboljenja i identifikaciju patogena, što doprinosi pravovremenoj i uspešnoj zaštiti.

AB  - Cucurbits production has a long tradition in our country. In some parts of the country, cucumber, watermelon and melon are the most important agricultural crops. High yield and good profit are often compromized by various biotic and abiotic factors. In years with favorable weather conditions cucurbit bacterial diseases can cause serious damage. This paper describes major bacterial diseases of cucurbit plants, such as angular leaf spot caused by Pseudomonas syringae pv. lachrymans, bacterial fruit blotch caused by Acidovorax citrulli, bacterial spot caused by Xanthomonas campestris, bacterial wilt caused by Erwinia tracheiphila and cucurbit yellow wine disease caused by Serratia marcescens, relatively new and invasive disease across the United States. In addition, bacterial leaf spot, caused by Pseudomonas syringae pv. syringae and Pectobacterium carotovorum subsp. carotovorum, inducing bacterial soft rot, are becoming more important in cucurbit production worldwide.
AB  - Biljke familije Cucurbitaceae se dugi niz godina gaje širom naše zemlje. U pojedinim krajevima, proizvodnja krastavca, lubenice i dinje predstavlja osnovni izvor prihoda za mnoga poljoprivredna domaćinstva.

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  - Bacterial spot caused by Xanthomonas euvesicatoria is considered one of the most important diseases of pepper in Serbia. In order to control this disease, copper based compounds (copper hydroxide, copper oxychloride, copper hydroxide + mancozeb, copper oxychloride + mancozeb), antibiotics (streptomycin sulfate and kasugamycin), resistance inducer (acibenzolar-S-methyl), antagonistic bacteria Bacillus subtilis (strains QST 713 and AAac), bacteriophage (strain K Phi 1) and one commercial microbial fertilizer, were tested for efficacy and compared to untreated control. The experiments were carried out in a greenhouse and climatic chamber conditions. Plants were inoculated with X euvesicatoria strain KFB 13 (10(8) CFU mL(-1)) using hand-held sprayer. Results of three experiments showed that all treatments except microbiological fertilizer significantly reduced intensity of bacterial spot symptoms compared to the untreated control. The most efficient treatment was acibenzolar-S-methyl reducing disease severity 93-97%. There was no statistically significant difference in efficacy of this treatment and copper hydroxide, copper oxychloride, copper hydroxide + mancozeb, copper oxychloride + mancozeb, streptomycin sulfate, kasugamycin and antagonistic strain QST 713 treatments. Application of antagonistic strain AAac and bacteriophage K Phi 1 significantly reduced disease intensity but less than the first group of treatments. Bacteriophage K Phi 1 (78-85% rH) was more effective in the climatic chamber compared to the efficacy (38% rH) in the greenhouse experiments.

There was no statistically significant difference in efficacy of this treatment and copper hydroxide, copper oxychloride, copper hydroxide + mancozeb, copper oxychloride + mancozeb, streptomycin sulfate, kasugamycin and antagonistic strain QST 713 treatments. Application of antagonistic strain AAac and bacteriophage K Phi 1 significantly reduced disease intensity but less than the first group of treatments. Bacteriophage K Phi 1 (78-85% rH) was more effective in the climatic chamber compared to the efficacy (38% rH) in the greenhouse experiments.",

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.
AB  - U leto 2014. godine, proizvođači lubenice iz sremskog okruga uočili su pojavu simptoma u vidu pega vodenastog izgleda i nepravilnog oblika na zrelim plodovima lubenice, koji su ukazivali na oboljenje bakteriozne prirode. 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  - Bacterial diseases are very common in potato crops, especially when weather conditions are favourable for the emergence and spread of infection. Bacteria belonging to the Pectobacterium and Dickeya genera, the causal agents of the blackleg and tuber soft rot of potato, are economically important pathogens that affect potato production worldwide, as well as in our country. According to recent classification, pectolytic bacteria, the pathogens of potato, have been differentiated as Pectobacterium atrosepticum, P. carotovorum subsp. carotovorum, P. carotovorum subsp. brasiliense, P. wasabiae and several Dickeya spp. The disease occurs on potato plants and tubers in the field, or during potato storage or transportation, thereby reducing yield and quality. The aim of this paper is to point to the distribution and economic importance of the blackleg and tuber soft rot of potato, as well as the characteristics of the pathogens. Information about symptoms and epidemiology of the disease are important for an accurate disease diagnosis and pathogen identification, contributing to the timely and successful protection strategy.

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.

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  - Bacterial spot, caused by bacteria that belong to Xanthomonas complex, is one of the widespread and economically important disease of pepper and tomato. Growing resistant genotypes, use of treatments based on copper compounds or streptomycin do not provide efficient control of this disease due to the appearance of new races of bacteria and development of strains resistant to antibiotics and copper compounds. Pepper and tomato producers do not have adequate resources for pathogen control since standard bactericides are not effective enough if weather conditions are favorable for the disease development. Due to lack of resistant cultivars and effective means of protection, researchers have searched for alternative solutions that would provide effective control of this disease. Only integration of different control methods can enable positive effect and achieve an adequate crop protection. Biological methods (use of bacteriophages) and some recent alternative treatments (Systemic Acquired Resistance inducers), have provided the possibility of developing an effective strategy for X. euvesicatoria control.

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  - Soft rot symptoms were observed on broccoli plants in several commercial fields in the western part of Serbia. Six strains of bacteria were isolated from diseased tissues and identified as Pectobacterium carotovorum subsp. carotovorum using conventional bacteriological and molecular methods. All strains were non-fluorescent, gram-negative, facultative anaerobes, oxidase-negative and catalase-positive, causing soft rot on potato and carrot slices and did not induce hypersensitive reaction on tobacco leaves. They grew in 5% NaCl and at 37C, did not produce acid from α-methyl glucoside, sorbitol and maltose, nor reducing substances from sucrose, but utilized lactose and trehalose, and did not produce indole or lecithinase. The investigated strains showed characteristic growth on Logan's medium and did not produce blue pigmented indigoidine on GYCA medium nor 'fried egg' colonies on PDA. The identity of strains was confirmed by ITS-PCR and ITS-RFLP analyses and by sequence analysis of the 16S rRNA gene. In a pathogenicity assay, all strains caused tissue discoloration and soft rot development on inoculated broccoli head tissue fragments.
