Where to get Xanthomonas?

Xanthomonas is a brand of Proteobacteria, abounding of which could cause bulb diseases. Most varieties of Xanthomonas are accessible from the National Collection of Bulb Pathogenic Bacteria (NCPPB) in the United Kingdom and added all-embracing ability collections such as ICMP in New Zealand, CFBP in France, and VKM in Russia. It is aswell taken out from M.T.C.C. India.
Xanthomonas can infect a wide variety of species including pepper, rice, citrus, cotton, tomato, and soybeans. 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.
Xanthomonas campestris is bacterial species that causes a variety of plant diseases. Available from the NCPPB,and other international Culture collections such as ICMP, ATCC, and LMG in a purified form, it is used in the commercial production of a high-molecular-weight polysaccharide - xanthan gum - that is an efficient viscosifier of water and that has many important uses, especially in the food industry.
Xanthomonas is a flagellated, rod-shaped bacteria, which allows the bacteria to move throughout an infected plant. Xanthomonas is dependent on the type III protein secretion system, which relies on transport protiens, secreting several hypersensitive reaction proteins and outer proteins, causing an interaction with the plant
Xanthomonas bacteria grow almost exclusively in plants. In São Paulo, Brazil, the numbers of citrus tress with citrus canker from Xanthomonas have grown at an astonishing rate. This has given the Brazilians no choice but to destroy not only the diseased trees, but trees within a 30m radius of the contaminated tree, putting the number of destroyed trees over 500,000 in 1998 alone
