摘要: 采用RAPD分子标记技术,分析了金钗石斛、铁皮石斛和齿瓣石斛三种石斛属植物的种间关系。10个引物产生的113条DNA扩增片段中,106条(93.81%)具有多态性,利用113个RAPD标记,计算遗传距离,利用非加权组平均法建立聚类图。结果表明,RAPD标记技术较好地从分子水平揭示金钗石斛、铁皮石斛和齿瓣石斛三种石斛属植物的遗传背景、亲缘关系,并为后期在DNA水平上对药用石斛的开发利用提供资料。

关键词: 石斛属, RAPD分析, 遗传多样性, 亲缘关系

Abstract: Three species of Dendrobium, D. nobile, D. officinale and D. devonianum were analyzed using random amplified polymorphic DNA (RAPD) markers. A total of 113 bands were amplified by 10 RAPD primers, among which 106 (93.81%) bands were polymorphic. The data of 113 RAPD bands were used to generate genetic distances and to construct a dendrogram by unweighted pair group method analysis (UPGMA). The results showed that the RAPD approach was efficient in studying genetic background and relationships among these 3 species and could be used to provide abundant molecular data for the medicinal development and utilization of Dendrobium.

Key words: Dendrobium, RAPD, genetic diversity, genetic relationship
