Abstract: 

The genetic diversity and population structure of Anemone altaica, an important medicinal herb used in traditional Chinese medicine, were estimated using ISSR markers within eight populations in Qinling Mountains, Northwestern China. The results showed that A. altaica has a relatively high genetic diversity (PPB = 89.9%, He = 0.293) at species level, and within populations (PPB = 61.7%, He = 0.215). Based on analyses of GST, AMOVA and gene flow a significant genetic differentiation was revealed. Influences of human harvesting activities on genetic diversity and population structures of A. altaica were determined by comparing their difference between over harvesting populations and low harvesting populations. At last, operative management policies for sustainable use of this species is suggested in this study.


Highlights

Anemone altaica has a high genetic diversity at species level and within populations. ► There is no significant genetic differentiation within and among natural populations. ► Medium harvesting intensity may benefit the maintenance of its genetic diversity. ► Long-term over-harvesting may impact on its genetic diversity.
