The genetic diversity of Centella asiatica analyzed in China

by Charaf Akaaboune

Centella Asiatica is considered an essential plant species used in traditional Chinese medicine. To help the efficient use and conservation of this species, a recent research has investigated the genetic diversity of Centella Asiatica populations in China using inter-simple sequence repeat (ISSR) markers.14 natural populations (a total of 162 individuals) has been used to estimate genetic diversity.
The results of this study showed a relatively high genetic diversity at the species level. At the population level, the genetic diversity of Jinhua, Zhejiang Province and Jiujiang, Jiangxi Province populations was relatively high too, whereas the genetic diversity of Guang’an, Sichuan Province and E’mei, Sichuan Province showed to be relatively low.

Centella Asiatica is considered an important plant species used in traditional Chinese medicine. To help the efficient use and conservation of this species, recent research has investigated the genetic diversity of Centella Asiatica populations in China using inter-simple sequence repeat (ISSR) markers. Fourteen natural populations (a total of 162 representatives) were used to estimate genetic diversity. The results of this study showed a relatively high genetic diversity of the species. AAt the population level, the genetic diversity of Jinhua, Zhejiang Province and Jiujiang, Jiangxi Province populations was relatively high. In contrast, the genetic diversity of Guang’an, Sichuan Province and E’mei, Sichuan Province showed to be relatively low.

The 14 populations were clustered into four groups based on abundant ISSR data, which further defined the genetic relationship among populations. Interestingly, the genetic clustering result was similar to previous chemical clustering results based on high-performance liquid chromatography (HPLC) data, classifying the 14 populations into four groups. By combining the clustering results and compare their difference in addition to genetic diversity data, this work provides a scientific basis for conserving populations of relatively high genetic diversity such as Jinhua, Zhejiang Province and Jiujiang, Jiangxi Province populations and helps to establish good agricultural practices (GAP) for Centella Asiatica.
