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 ...
Dowson [3] later reclassified the bacterium as Xanthomonas campestris and proposed the genus Xanthomonas. [4] Xanthomonas was first described as a monotypic genus and further research resulted in the division into two groups, A and B. [5] [6] Later work using DNA:DNA hybridization has served as a framework for the general Xanthomonas 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 ...
Several sRNAs have also been identified in Xanthomonas campestris pathovar campestris. Some of these X. campestris sRNAs are only found in Xanthomonas, some are also expressed in other bacteria. [1] [2] Several of these sRNAs appear to contribute to virulence, including sX12, sX13 and sRNA-Xcc1. [1] [3] [4]
