Diversity ofXanthomonasSpp. Causal Agents of Bacterial Spot on Pepper and Tomato Plants in Bulgaria

Differentiation ofXanthomonasspp. Causing Bacterial Spot in Bulgaria Based on Biolog System

“…Twenty-seven strains were derived from the resident phase of the pathogen on weeds (1989–1999) from and around tomato fields. The bacteria were identified by PCR amplification with species-specific primers as Xanthomonas euvesicatoria (54 strains from pepper), Xanthomonas vesicatoria (115 strains: 29 from pepper, 59 from tomato, and 27 from weeds) and Xanthomonas gardneri (15 from tomato) ([ 9 , 10 ], Kizheva et al, unpublished). Biolog GN2 (Biolog, Inc., Hayward, CA, USA) microplates were used for obtaining metabolic fingerprints.…”

Broad host range bacteriophages found in rhizosphere soil of a healthy tomato plant in Bulgaria

“…For the last nearly 30 years prof. Bogatsevska and coworkers have had a great contribution to the study of bacterial-spot-causing xanthomonads in Bulgaria as they isolated and characterized a large number of strains from infected tomato and pepper plants (Bogatsevska and Sotirova, 1992;2022). The major bacterial spot causative agents on tomato plants in Bulgaria are X. vesicatora followed by X. gardneri and on pepper plants -X. euvesicatoria (Kizheva et al, 2011(Kizheva et al, , 2013Vancheva et al, 2018). The first report of X. euvesicatoria isolated from infected tomato plants in Bulgaria was made in 2020 (Kizheva et al, 2020).…”

Draft Genome Sequences of Two Xanthomonas euvesicatoria Strains from the Balkan Peninsula

“…Taxonomy and diversity of bacterial spot agents have been studied by phenotypic, biochemical, and DNA-based methods ( 4 ). When we applied these methods to Xanthomonas euvesicatoria strains isolated on the Balkan Peninsula ( 3 , 5 – 9 ), we realized that these markers are not suitable to measure most population genetic parameters. A precise molecular typing tool for identification and differentiation is necessary for monitoring populations infecting pepper and tomato plants in order to develop strategies to control the disease in fields.…”
