Comparison of genomes belonging to different P. syringae pathovars.

DROPSA is a 4-year project involving 26 partners from Europe, Asia, New Zealand and North America. It focuses on new and emerging threats to the fruit industry due to cherry fruit fly Drosophila suzukii, as well as the bacterial pathogens Pseudomonas syringae pv. actinidiae, Xanthomonas fragariae and X. arboricola pv. pruni. These pathogens are a major concern because neither eradication nor containment are possible; hence the development of targeted integrated pest management (IPM) is vital to minimize the economic impact on fruit production in the EU region.

The EGSB group is leading the WP3 on biology and epidemiology of bacterial diseases as well as the Task 3.2 “Pathogen source-tracking and evolutionary risks” and Task 3.5 “Pathogen interactions with insect pollinators and Drosophila suzukii”. For this purpose, we have developed on-site detection tools for the three bacterial pathogens using comparative genomics (Bühlmann et al., 2013; Gétaz et al., 2017; Ruinelli et al., 2017). We have also established source-tracking tools for the X. fragariae pathogen for genotyping isolates and determining inoculum reservoirs and invasion routes impacting disease outbreaks.
