| Outline of Annual Research Achievements |
Nuclear and chloroplast SSR markers for Japanese Tsuga species were designed using NGS. Using these markers significant genetic structure across the species ranges was found with both northern and southernmost populations the most diverged. Genetic diversity is correlated with past logging in the temperate forest species, T. sieboldii, but not in the subalpine T. diversifolia where human impacts have been less. Although not identified using SSR markers RAD-seq data identified low levels of hybridisation between the two species.
In Fagus crenata, whole chloroplast genome sequencing revealed that there are two strongly diverged clades in Japan, one in western Japan that is closest to the chinese species F. engleriana and the other in eastern Japan.
