| Outline of Final Research Achievements |
Increasing yield is important target of crop breeding. Recent progress of DNA sequencing technologies, by combination of population genetics, enable to study genetic factors regulating yield. It is important to understand molecular mechanisms of stress tolerance of plants because it is most severe yield limiting factor in various crops. Using high-density SNPs information in Arabidopsis, we analyzed stress tolerance mechanisms (and its mechanisms of variation), by GWAS and analysis of epistatic interactions. Our analysis identified novel mechanisms of stress tolerance, which is regulated by a combination of epistatic interaction of genes.
