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]

Pathovars[edit]

  • Pseudomonas savastanoi pv. fraxini causes ash canker.[6]
  • Pseudomonas savastanoi pv. nerii attacks oleander.[6]
  • Pseudomonas savastanoi pv. savastanoi causes olive knot.[4]
  • Pseudomonas savastanoi pv. phaseolicola attacks Phaseolus (bean) plants [7]
