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.
It is a parasite of plants including pepper and tomatoes, causing spots on infected leaves and fruit. [1] X. perforans shows most growth at temperatures of 25-30C. [2] It is widespread, but mostly found in North and South America. [3]
Xanthomonas species can cause bacterial spots and blights of leaves, stems, and fruits on a wide variety of plant species. [15] Pathogenic species show high degrees of specificity and some are split into multiple pathovars , a species designation based on host specificity.

Gene-for-gene patterns control the interactions between the Xanthomonas campestris, a bacterial pathogen, and plants. Avr genes are a group of genes that impact the specificity of the interaction between the bacteria and the plant host. When either these bacterial genes or a plant's resistance genes to the pathogen are not present, the ...

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.
