Abstract

The objective of this study was to evaluate genetic diversity of 35 Huperzia samples collected from the different ecological areas in Vietnam by using rbcL markers. The results revealed that the samples were genetically diverse in high genetic similarity which ranged from 98.0 to 99.0%, respectively. Based on the Genbank data in comparison, it was ascertained that only one sample (BK3) is a member of H.phlegmarioides group, and others belonged H. squarrosa group as divided into two main groups by phylogenetic tree analyses. It suggests that some Huperzia samples may plausibly descend from the same origin, evolution and arising relations. This study has provided useful information for further identifying the high-quality genetic plant sources for propagation, development and conservation of the high-valued medicinal materials of Huperzia plants in this country.

利用分子标记评价越南不同地区石杉属植物的遗传多样性及鉴定
本研究的目的是利用rbcL标记评估从越南不同生态区采集的35个石杉样本的遗传多样性。结果表明,这些样品具有较高的遗传相似性,遗传多样性分别为98.0%至99.0%。根据Genbank的数据进行比较,通过系统发育树分析,确定只有一个样本(BK3)属于狭叶蜂群,其他样本属于方叶蜂群。这表明,一些壶菌样本可能来自相同的起源、进化和产生关系。本研究为进一步确定优质遗传植物来源,为我国高价值的石杉药材的繁殖、开发和保护提供了有益的信息。
