Bacterial seedling blight of rice (Oryza sativa), caused by pathogen Burkholderia plantarii [4] Early blight of potato and tomato, caused by species of the ubiquitous fungal genus Alternaria Leaf blight of the grasses e.g. Ascochyta species [ 5 ] and Alternaria triticina that causes blight in wheat [ 6 ]
An example of this is the partnership with the leaf-mining fly Scaptomyza flava, which creates holes in leaves during oviposition that the pathogen can take advantage of. [22] The role of taxis in P. syringae has not been well-studied, but the bacteria are thought to use chemical signals released by the plant to find their host and cause infection.

Candidatus L. africanus
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 ...
