Xanthomonas is a genus of Proteobacteria, many of which cause plant diseases. Most varieties of Xanthomonas are available from the National Collection of Plant Pathogenic Bacteria (NCPPB) in the United Kingdom and other international culture collections such as ICMP in New Zealand, CFBP in France, and VKM in Russia. It is also taken out from M.T.C.C. India.
Xanthomonas can infect a wide variety of species including pepper, rice, citrus, cotton, tomato, and soybeans. [1] Some types of Xanthomonas cause localized leaf spot or leaf streak while others spread systemically and cause black rot or leaf blight disease. They inject a number of effector proteins, including TAL effectors, into the plant via their type iii secretion system.
