Xanthomonas Campestris

Xanthomonas campestris is a type of bacteria found in soil and on plant surfaces. It is a Gram-negative, rod-shaped bacterium, and is particularly notable for its ability to cause plant diseases. It is a respected model organism used in the study of plant-pathogenic bacteria, as well as being exploited as a source of industrial enzymes. Xanthomonas campestris can cause a variety of diseases in different plants; most notably, it is the cause of the disease known as black rot in crucifers such as cabbage and cauliflower. Its ability to cause these diseases makes it an agricultural pest, and a subject of much research into the prevention and control of plant diseases.
