Outline of Final Research Achievements |
Overseas surveys were conducted in areas centered on the Kenai peninsula in southern Alaska and inland in the Denali National Park. We gathered plants at 4 sites and collected samples used for DNA analysis from alpine plants (35 species in total) distributed commonly in Japanese archipelago such as Minnesota and Ezo Azalea (total of 419 samples). In addition to overseas surveys, DNA was extracted from samples collected in previous surveys and surveys this year and genetic diversity in nuclear genes was analyzed. This year, we found three genetic groups from Chubu region of the Japanese archipelago, middle part of Hokkaido and eastern part of Hokkaido to Alaska with emphasis on Phyllodoce aleutica. This result was orally presented at the Annual Meetings of Japanses Society for Plant Taxonomists on March 2017 at Kyoto Univeristy.
