Outline of Final Research Achievements

To understand the evolutional history of Bursaphelenchus xylophilus, the causal pathogen of the pine wilt disease, we performed population and comparative analyses of genomes of the nematodes using Japanese isolates and native North American isolates. Population analysis using microsatellite and SNPs suggested high genetic diversity among Japanese isolates and multiple introductions of the pathogen from North America to Japan.
