Pseudomonas savastanoi
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] It is named after Savastano, a worker who proved between 1887 and 1898 that olive knot are caused by bacteria.[2][3]

The pathovar of greatest economical significance is Pseudomonas savastanoi pv. savastanoi, 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.[4][5]
History
One of the first scientists to carry out scientific and modern research on the disease of olive trees caused by Pseudomonas savastanoi (Italian: la rogna dell'ulivo) was Giuseppe Maria Giovene (1753-1837), who explained his conclusions in his publication Sulla rogna degli ulivi (1789).[6]
