Xanthomonas campestris pv.vesicatoria is a bacterium that causes bacterial leaf spot (BLS) on peppers and tomatoes. It is a gram-negative and rod-shaped. [1] It causes symptoms throughout the above-ground portion of the plant including leaf spots, fruit spots and stem cankers.
Relatively recent studies by Turecheck et al. [5] have shown heat treatments to be successful in dealing with angular leaf spot. They found that the number of living Xanthomonas fragariae were reduced by a minimum of 10 5-10 6 CFU/ml after exposing infected plants to heat treatments of 44-48 o C for 2–4 hours. [11]
Citrus canker, caused by Xanthomonas citri subsp. citri is an economically important disease of many citrus species (lime, orange, lemon, pamelo, etc.) [11] Bacterial leaf spot has caused significant crop losses over the years. Causes of this disease include Xanthomonas euvesicatoria and Xanthomonas perforans = [Xanthomonas axonopodis (syn ...
Xanthomonas campestris is commonly used industrially to produce a water-soluble exo-polysaccharide, known as xanthan gum, from fermentation of carbon sources like glucose. [5] In this process, a preserved culture of the gram-negative bacterium is expanded through growth and then used as an inoculum in bioreactors with liquid growth media .
Bacterial leaf streak (BLS), also known as black chaff, is a common bacterial disease of wheat. The disease is caused by the bacterial species Xanthomonas translucens pv. undulosa. The pathogen is found globally, but is a primary problem in the US in the lower mid-south and can reduce yields by up to 40 percent. [6]
Bacterial leaf scorch (commonly abbreviated BLS, also called bacterial leaf spot) is a disease state affecting many crops, caused mainly by the xylem-plugging bacterium Xylella fastidiosa. [1] It can be mistaken for ordinary leaf scorch caused by cultural practices such as over-fertilization.
Xanthomonas campestris pv. raphani is a gram-negative, obligate aerobic bacterium that like many other Xanthomonas spp. bacteria has been found associated with plants. This organism is closely related with Xanthomonas campestris pv. campestris, but causes a non-vascular leaf spot disease that is clearly distinct from black rot of brassicas.
