Abstract
Pseudomonas syringae pv. actinidiae (Psa) is the causal agent of the bacterial canker of kiwifruit, affecting the kiwifruit cultivation worldwide. Due to its large spread and detrimental effects on kiwi production, this pathogen has been extensively studied and it is currently divided into five different biovars. Taking advantages of the recent possibility to compare whole genome sequences instead of few targeted genetic markers, here we provide the first comparative genome analysis of 153 Psa genome sequences available in the NBCI public database. The results of this pangenome analysis, beside supporting previous phylogenetic characterisations, provides new details about the pathogenicity features of the different biovars.
