Discovery of ancestral diploid lineage of Betula ermanii in Japan's high mountains
Betula ermanii, a tree species native to the high mountains in Japan and the cold and snowy regions of Russia, is usually tetraploid (possessing four genome sets). However, the species found on Shikoku Island and Kii Peninsula are diploid with only two genome sets, suggesting an ancestral lineage.
