Abstract
Pantoea agglomerans strains inducing a hypersensitive reaction in tobacco leaves are frequently isolated inside olive knots caused by Pseudomonas savastanoi pv. savastanoi. Here, we report the draft genome sequence of the Italian P. agglomerans strain, which is able to increase olive knot disease severity when coinoculated with P. savastanoi pv. savastanoi.
Highlights
Pantoea agglomerans strains inducing a hypersensitive reaction in tobacco leaves are frequently isolated inside olive knots caused by Pseudomonas savastanoi pv. savastanoi
Many bacterial species live inside olive knots caused by Pseudomonas savastanoi pv. savastanoi and belong mainly to the genera Pantoea, Pectobacterium, Erwinia, and Curtobacterium [1]
We have frequently isolated P. agglomerans strains inducing a hypersensitive reaction (HR) in tobacco plants, and we demonstrated that one of them (DAPP-PG 734) (i) forms a stable interspecies community with P. savastanoi pv. savastanoi, (ii) communicates through a quorum-sensing system mediated by N-acyl-homoserine lactones, and (iii) increases disease severity when coinoculated with the pathogen in olive plants [2, 3]

Many bacterial species live inside olive knots caused by Pseudomonas savastanoi pv. Savastanoi and belong mainly to the genera Pantoea, Pectobacterium, Erwinia, and Curtobacterium [1].
