Pseudomonas savastanoi is a Gram-negative plant pathogenic bacterium that infects a variety of plants. It was once considered a pathovar of Pseudomonas syringae, but following DNA-relatedness studies, it was instated as a new species^[1].

The pathovar of greatest economical significance is Pseudomonas savastanoi pv. oleae, which causes the disease olive knot. Symptoms include formation of galls on infected trees; tumour formation is induced by indoleacetic acid biosynthesis by the bacteria, in a similar manner to the well-studied crown gall pathogen, Agrobacterium tumefaciens^[2].

[edit] Pathovars

Pseudomonas savastanoi pv. fraxini causes ash canker^[3].

Pseudomonas savastanoi pv. nerii attacks oleander^[3].

Pseudomonas savastanoi pv. oleae causes olive knot^[3].

Pseudomonas savastanoi pv. phaseolicola attacks Phaseolus (bean) plants ^[4]
