基于叶绿体DNA rps16序列的福建泰宁野生铁皮石斛多样性分析
Diversity Analysis Based on Chloroplast DNA rps1 6 Sequence for Wild Dendrobium officinale from Taining,Fuj ian
摘要
Abstract
A diversity analysis based upon the rps1 6 sequence of chloroplast DNA for the wild Dendrobium officinale found in Taining,Fuj ian and other areas was conducted.The results indicated an average genetic distance among 75 species of Dendrobium to be 0.006 6,and 0.000 6 for those from Taining.There were 5 polymorphic sites (i.e.,25% of the total)detected in the 38 wild D.officinale from Taining.The maximal genetic distance calculated by K-2P was 0.003 4,indicating significant sequence variations and high diversities among the Taining species.In addition,among the 5 different types of rps16 sequence,T2,T65,and D5 were found only in D. officinale collected from Taining.关键词
