Further investigation of pathogenicity profiles and multilocus sequencing typing suggested that the list could be narrowed down to just three main pathovars with the different symptoms being black rot, leaf spot, and bacterial blight. [8] Both X. campestris pv. campestris (known for causing black rot of crucifers) and X. campestris pv.

Xanthomonas actively kill other bacterial using type IV secretion system and defend itself from amoeba using type VI secretion system. [19] [20] [1] To prevent infections, limiting the introduction of the bacteria is key. Some resistant cultivars of certain plant species are available as this may be the most economical means for controlling ...
Bacterial spot of peppers and tomatoes is caused by the bacteria Xanthomonas campestris pv. vesicatoria. [citation needed] 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]
Black rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc), is considered the most important and most destructive disease of crucifers, infecting all cultivated varieties of brassicas worldwide. [1] [2] This disease was first described by botanist and entomologist Harrison Garman in Lexington, Kentucky, US in 1889. [3]
Septoria lycopersici infects the tomato leaves via the stomata and also by direct penetration of epidermal cells. [3] Symptoms generally include circular or angular lesions most commonly found on the older, lower leaves of the plant. [1] The lesions are generally 2–5 mm in diameter and have a greyish center with brown margins.
