Xanthomonas
''Xanthomonas'' (from greek: ''xanthos'' – "yellow"; ''monas'' – "entity") is a genus of bacteria, many of which cause plant pathology, plant diseases. There are at least 27 plant associated ''Xanthomonas spp.'', that all together infect at least 400 plant species. Different species typically have specific host and/or tissue range and colonization strategies. Taxonomy The genus ''Xanthomonas'' has been subject of numerous taxonomic and phylogenetic studies and was first described as ''Bacterium vesicatorium'' as a pathogen of pepper and tomato in 1921. Dowson later reclassified the bacterium as ''Xanthomonas campestris'' and proposed the genus ''Xanthomonas''.''Xanthomonas'' was first described as a monotypic genus and further research resulted in the division into two groups, A and B. Later work using DNA:DNA hybridization has served as a framework for the general ''Xanthomonas'' species classification. Other tools, including multilocus sequence analysis and amplified fragmen ...

Xanthomonas Campestris
''Xanthomonas campestris'' is a gram-negative, obligate aerobic bacterium that is a member of the Xanthomonadaceae, a family of bacteria that are commonly known for their association with plant disease. This species includes ''Xanthomonas campestris'' pv. ''campestris'', the cause of black rot in brassicas (cruciferous vegetables), one of the most important diseases of brassicas worldwide. These bacteria are facultative saprophytes, meaning that they are typically parasitic while also having the ability to live on dead or decaying organic matter under the proper conditions. Upon initial infection, the bacteria remain in the epiphytic stage; however, the harmful endophytic stage is reached when the bacteria actually enter the plant host through natural openings. In general, the genes that contribute significantly to the plant-bacteria relationship are the avirulence (''avr'') genes, the hypersensitivity response and pathogenicity (''hrp'') genes, and the pathogenicity factors ...

Bergey's manual of systematic bacteriology, Volume Two: The Proteobacteria, Part B: The Gammaproteobacteria. New York: Springer . The type strain iNCPPB1469from ''Fragaria chiloensis'' var. ''ananassa''. Environment Favorable environmental factors for ''Xanthomonas fragariae'' are not fully understood and need to be studied more. It has been noticed, however, that ''X. fragariae'' thrive in humid climates. ''Xanthomonas fragariae'' are also most prevalent in climates with cool to moderate temperatures.Heidenreich, Cathy, and Bill Turechek. “Bacterial Angular Leaf Spot of Strawberry.” Cornell University, 1998. https://s3.amazonaws.com/assets.cce.cornell.edu/attachments/21537/strawberry-angularlfspotfs.pdf?1490125142 Host & symptoms Infection caused by the angular leaf spot pathogen first appears as water-soaked lesions found ...
