Bacterial fasciation
Rhodococcus fascians

Bacterial fasciation (Rhodococcus fascians) is a bacterial pathogen.

Rhodococcus fascians is a Gram positive bacterial phytopathogen that causes leafy gall disease. R. fascians is the only phytopathogenic member of the Rhodococcus genus; its host range includes both dicotyledonous and monocotyledonous hosts. Because it commonly afflicts tobacco plants, it is an agriculturally significant pathogen. Infected plants show typical symptoms, such as leaf deformation, witches broom and leaf gall, which development depends on the plant's cultivar, plant's age, and the bacterial strain.
