Recurring epidemics of kiwifruit(Actinidia spp.) bleeding canker disease are caused by Pseudomonas syringae ***(Psa).In order to strengthen understanding of population structure,phylogeography,and evolutionary dynamics,we isolated Pseudomonas from cultivated and wild kiwifruit across six provinces in *** on the analysis of 80 sequenced Psa genomes,we show that China is the origin of the pandemic lineage but that strain diversity in China is confined to just a single *** contrast,Korea and Japan harbor strains from multiple *** independent transmission events marked introduction of the pandemic lineage into New Zealand,Chile,Europe,Korea,and *** high similarity within the core genome and minimal impact of within-clade recombination,we observed extensive variation even within the single clade from which the global pandemic arose.
