| Outline of Final Research Achievements |
In this study, we analyzed the genetic background of evolution and the molecular mechanism for serpentinous soil adaptation of Aster savatieri.
Population structure analysis by SSR was performed on 38 populations including Aster savatieri and var. pygmaeus. As a result, it became clear that the whole is divided into three groups with geographical cohesion. Moreover, it was suggested that var. pygmaeus evolved independently at least twice in Aichi and Mie / Kochi. In addition, as a result of reference preparation with RNA-seq, polymorphism detection, and comparison of gene expression profiles, FRD 3 was searched for as a result of searching for genes with GO related to heavy metal tolerance.
