Abstract
Fagus hayatae Palib., a rare and statutory-conserved plant in Taiwan, is distributed in Chatienshan Nature Reserve, Tongshan area, and few new single mountain areas. It can also be found in Sichun province, Hubei province, and Zhejiang province in China. A population genetics research on this endangered species was conducted by using chloroplast trnL–F and rbcL–atpB regions; three microsatellite markers developed for Fagus crenata were also examined in Fagus hayatae on the nine populations in Taiwan and three populations in China. Results showed that a low variation in Taiwan''s populations using chloroplast markers, and a close relationship with the related taxa from China. Results also indicated a clear divergence of the populations from Syue Mountain (Beicha, Loupei, Lala, Niauzui, and Ayu) and Central Mountains (Lenkan, Dabai, Taipin Beech Trail, and Tongsan). By conducting microsatellite analysis, populations in Taiwan exhibited low level of genetic variation, while populations in China had higher level of genetic variation, especially for Zhejian’s population. Nevertheless, results of Bayesian clustering analysis suggested that populations in Taiwan and China should be considered as a single genetically distinct group. The results from microsatellite data provide more genetic information and therefore can be a great resource for further population genetics studies, hopefully provide applications to conservation biology of Fagus hayatae in Taiwan.
