[5][6] 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).

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.

[10] These results demonstrate disease enhancing cooperation but also reveal a possible way that undiscovered cheating may be occurring.
