Pseudomonas savastanoi is a

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.[2]
It is named after Savastano, a worker who proved between 1887 and 1898 that olive knot are caused by bacteria.[3][4]

The pathovar of greatest economical significance is Pseudomonas savastanoi pv. savastanoi, which causes the disease

indoleacetic acid biosynthesis by the bacteria, in a similar manner to the well-studied crown gall pathogen, Agrobacterium tumefaciens.[5][6]

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).[7]

Pathovars

Quorum sensing

P. s. pv. s. has an unusual

order, the Enterobacterales.[10] Hosni et al., 2011 and Caballo-Ponce et al., 2018 find P. s. pv. s. produces very similar N-Acyl homoserine lactones (AHLs) to the Erwiniaceae Erwinia toletana and Pantoea agglomerans.[10] Hosni find an avirulent mutant – defective for AHL production – is restored to virulence by the presence of E. toletana and P. agglomerans.[10] These results demonstrate disease enhancing cooperation but also reveal a possible way that undiscovered cheating may be occurring.[10]
