Genetic diversity of Centella asiatica in China analyzed

Centella asiatica is considered to be an important 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 (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.

The 14 populations were clustered into 4 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, which would also classify the 14 populations into four groups.By combining the clustering results and compared 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 establishing good agricultural practices (GAP) for Centella Asiatica.
