[edit] Surface Characteristics
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.
[edit] Transmission
Symptoms of citrus canker, including small yellow lesions, can begin to appear as soon as only one week after the initial infection up to two months afterwards. Eventually, the initial yellow lesions turn brown and form a 'corky' surface, providing a method for later transmission to other plants and tissues.
[edit] Pathogenic Activity
Xanthomonas affects many types of hosts, including citrus, beans, grapes, cotton, and rice. It is main causative organism of Yellow disease(is the most important disease of hyacinths). The bacteria present in the bulb at planting can spread from the bulb into the leaves, and from early spring onward the disease can be dispersed in the field by rain and wind. In addition, machines used for the lifting and sorting of bulbs and knives used for scooping and scoring can spread the bacteria from diseased bulbs to healthy ones.
