Limited genetic diversity and high differentiation in Angelica dahurica resulted from domestication: insights to breeding and conservation.

ABSTRACT:

Background

Angelica dahurica belongs to the Apiaceae family, whose dry root is a famous traditional Chinese medicine named as "Bai zhi". There are two cultivars (A. dahurica cv. 'Hangbaizhi' and A. dahurica cv. 'Qibaizhi'), which have been domesticated for thousands of years. Long term artificial selection has led to great changes in root phenotypes of the two cultivars, and also decreased their adaptability to environment. We proposed hypothesis that the cultivars may have lost some of the genetic diversity found in the wild species and may be highly differentiated from the latter during the domestication process. However, few studies have been carried out on how domestication affected the genetic variation of this species. Here, we accessed the levels of genetic variation and dif
