Genome sequencing of Xanthomonas campestris pv. raphani from WHRI collection
Xanthomonas campestris pv. raphani is a pathovar (pathogenic variant) of the bacterial species Xanthomonas campestris. It specifically affects plants in the Brassicaceae family, including radishes (Raphanus sativus) and other cruciferous vegetables.Xanthomonas campestris pv. raphani causes a disease known as bacterial leaf spot or bacterial blight in radishes and related crops. The bacteria enter the plant through wounds or natural openings and colonize the leaf tissues, leading to the development of characteristic symptoms.The symptoms of bacterial leaf spot caused by Xanthomonas campestris pv. raphani include small, water-soaked lesions on the leaves that may expand and turn brown or black over time. These lesions often have a yellow halo surrounding them. In severe cases, the lesions can coalesce, causing extensive damage to the foliage and reducing the overall quality and marketability of the crop.
