| 摘要 | A thorough understanding of the levels and partitioning of genetic variation across populations and geographical regions of endangered species is a prerequisite to ensure effective conservation and/or restoration activities. Here, we examined chloroplast DNA (cpDNA) trnH-psbA intergenic spacer sequences variation within Notopterygium forbesii, an endangered and endemic perennial herb in China. Sequence data obtained from 141 individuals in 14 populations revealed twenty-two haplotypes. A high level of haplotype diversity (Hd = 0.81) and low level of nucleotide diversity (Pi = 0.0047) were detected. Low genetic differentiation among populations and also among regions was consistently indicated by both hierarchical analyses of molecular variance (AMOVA) and the structure of a neighbor-joining tree. Low level of population differentiation between populations or between regions in cpDNA sequences may be due to effects of the abundance of ancestral haplotype sharing and the high number of private haplotypes fixed for each population. Based on our results, we proposed some conservation strategies. Crown Copyright (C) 2010 Published by Elsevier Ltd.
