Preliminary transcriptomic analyses reveal and overexpression of various bacteriocins in .

Introduction: is a phytopathogenic bacterium of worldwide importance causing detrimental diseases in several crops. Recent reports from European and Mediterranean countries raised great concerns and have given impetus to new studies investigating both the pathogenicity of the newly emerged strains and the susceptibility and vulnerability of Mediterranean agroecosystems, with the outbreak in olive trees in southern Italy being the most investigated new pathosystem. The complexity of this pathogen makes difficult to understand its interaction mechanisms with host plants and plant microbial communities.
