Xanthomonas campestris pv. raphani is a gram-negative, obligate aerobic bacterium that like many other Xanthomonas spp. bacteria has been found associated with plants. This organism is closely related with Xanthomonas campestris pv. campestris, but causes a non-vascular leaf spot disease that is clearly distinct from black rot of brassicas.
campestris, X. campestris pv. incanae, and X. campestris pv. raphani, [8] but still included a small number of other pathovars like X. campestris pv. plantaginis and X. campestris pv. papavericola. Further investigation of pathogenicity profiles and multilocus sequencing typing suggested that the list could be narrowed down to just three main ...

Xanthomonas axonopodis is a rod-shaped Gram-negative bacterium with polar flagella. The bacterium has a genome length around 5 megabase pairs. A number of types of citrus canker diseases are caused by different pathovars and variants of the bacterium: [4] The Asiatic type of canker (canker A), X. axonopodis pv.
Causes of this disease include Xanthomonas euvesicatoria and Xanthomonas perforans = [Xanthomonas axonopodis (syn. campestris) pv. vesicatoria], Xanthomonas vesicatoria, and Xanthomonas gardneri. In some areas where infection begins soon after transplanting, the total crop can be lost as a result of this disease. [16] Xanthomonas campestris pv.
Black rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc), is considered the most important and most destructive disease of crucifers, infecting all cultivated varieties of brassicas worldwide. [1] [2] This disease was first described by botanist and entomologist Harrison Garman in Lexington, Kentucky, US in 1889. [3]

In molecular biology, Xanthomonas sRNA are small RNAs which have been identified in various species of the bacterium Xanthomonas. Analysis of the plant pathogen Xanthomonas campestris pv. vesicatoria revealed expression of seven cis-encoded antisense RNAs (asX1-asX7) and 15 intergenic sRNAs (sX1 - sX15).
