Xanthomonas Invasion: Type III Secretion System
Gram-negative bacteria of the genus Xanthomonas infect more than 300 different species worldwide. Xanthomonas campestris pv. vesicatoria causes bacterial spot disease on pepper and tomato plants.
The bacteria enter the plant intercellular spaces via natural openings.
Bacterial surface structures allow the attachment to host cells.
Xanthomonas produces the extracellular polysaccharide xanthan  that protects the bacteria from environmental factors.
An essential pathogenicity factor is the type III protein secretion system which spans the bacterial membranes…
… And is associated with an extracellular pilus.
The pilus is connected to a channel-like translocon that is inserted into the plant plasma membrane.
The type III secretion system transports approximately 30 different bacterial effector proteins into the plant cell.
Bacterial effector proteins are transported to different cellular compartments and manipulate host cellular pathways. Some effector proteins reach the plant cell nucleus and modify plant gene expression.
Effector proteins suppress plant defense responses and promote bacterial multiplication at the infection site.
