| Outline of Final Research Achievements |
Development of a new method analyzing acaricide resistance factor using genome mapping in the two-spotted spider mite was aimed in this study. To construct genome map, genetic linkages among microsatellite (SSR) loci, which position in scaffolds had been determined, were analyzed in the two-spotted spider mite. Consequently, 26 scaffolds of 40 largest scaffolds (> 90% of a hole genome) were mapped into the resulting five linkage groups of SSRs.
Resistance genes to pyridaben, a mitochondrial electron transport complex I inhibitors, was analyzed by QTL analysis. A significant QTL was indicated at scaffold 7 where PSST gene, a component of the complex I, existed, and the significant QTL area was extended to the next 10 cM, where one pseudo and five full-length cytochrome P450 monooxygenase genes were found. Previous studies suggested involvement of pyridaben resistance with cytochrome P450 functions.
