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.
Infection caused by the angular leaf spot pathogen first appears as water-soaked lesions found on the lower surface of strawberry leaves. These water-soaked lesions are the result of bacterial colonization within the plant leaf tissue. Lesions typically get larger as the infection worsens, and the enlarged lesions then form translucent spots.
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 a gram-negative, obligate aerobic bacterium that is a member of the Xanthomonas genus, ... leaf spot, and bacterial blight. [8] ...
Bacterial spot of peaches is caused by the bacteria Xanthomonas campestris pv. pruni. Spots may form on the leaves and they can be mistaken for peach scab, which is caused by a fungus. [citation needed] Bacterial leaf scorch of pecans is caused by the bacteria Xylella fastidiosa subsp. multiplex.
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.
Xanthomonas axonopodis pv. malvacearum Bacterial blight of cotton is a disease affecting the cotton plant resulting from infection by Xanthomonas axonopodis pathovar malvacearum (Xcm) a Gram negative, motile rod-shaped, non spore-forming bacterium with a single polar flagellum
Citrus canker is a disease affecting Citrus species caused by the bacterium Xanthomonas (X.axonopodis; X. campestris).Infection causes lesions on the leaves, stems, and fruit of citrus trees, including lime, oranges, and grapefruit.
