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.
Xanthomonas campestris pv. campestris also has some limited ability to infect the plant host through the stomata. Xanthomonas pv. raphani has been found to enter the plant through its stomata to cause infection of the tissue, or rather parenchyma. This results in bacterial spot on a wider range of hosts, which includes both crucifers and ...

Xanthomonas (from greek: xanthos – "yellow"; monas – "entity") is a genus of bacteria, many of which cause plant diseases. [1] There are at least 27 plant associated Xanthomonas spp. , that all together infect at least 400 plant species.

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]
The xanthoferrin siderophores are reportedly produced by Xanthomonas campestris pathovars, Xanthomonas orayzae pv. oryzae, Xanthomonas citri pathovars, and Xanthomonas oryzae pv. oryzicola. [6] [3] However, the xanthoferrin synthesis genes are conserved throughout the members of Xanthomonas group of plant pathogens and several other bacteria ...
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).
