Both X. campestris pv. campestris (known for causing black rot of crucifers) and X. campestris pv. incanae (known for causing bacterial blight of garden stocks) are vascular pathogens, and they have been found to invade the plant host through wounds or hydathodes. Xanthomonas campestris pv.
Xanthomonas translucens is a species of phytopathogenic bacteria. It is the causal agent of bacterial leaf streak in of wheat and cereal crop. The bacterium is transmitted as a seed-borne pathogen. The transmission rate is very low but ensures serious outbreaks in the field under suitable conditions.
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 disease is caused by the bacterial species Xanthomonas translucens pv. undulosa. The pathogen is found globally, but is a primary problem in the US in the lower mid-south and can reduce yields by up to 40 percent. [6]
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.
Pseudomonas syringae pv. syringae: Bacterial wilt (Murcha-de-Curtobacterium in Portuguese) Curtobacterium flaccumfasciens pv. flaccumfasciens = Corynebacterium flaccumfaciens subsp. flaccumfaciens. Common bacterial blight (Crestamento-bacteriano-comum in Portuguese) Xanthomonas campestris pv. phaseoli = Xanthomonas axonopodis pv. phaseoli ...
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.
The role of xanthoferrin in virulence varies among different Xanthomonas spp. Xanthoferrin mediated iron uptake contributes to the optimum virulence of Xanthomonas oryzicola and Xanthomonas campestris on their respective hosts but does not play any role in the virulence of Xanthomonas oryzae.
