英文摘要 | To explore the influence of vicariance on differentiation patterns of taxa in arid regions, we systematically assessed the genetic diversity and variability of Capparis spinosa, a typical xerophyte that is widely distributed in the Tianshan Mountains and adjacent areas. In total, 300 individuals from 25 populations were sampled, and 14 haplotypes were identified using two cpDNA sequences (rpS12-rpL20 and ndhF). A high level of total genetic diversity (H-T = 0.859) was detected, and this was attributed to the extensive distribution range, which included numerous large populations. The SAMOVA results suggested that the 25 populations were clustered into 4 major geographical groups; a similar divergence trend was found by constructing a BEAST phylogenetic tree and a network diagram. The AMOVA results revealed that significant genetic differentiation occurred among groups. Our results indicated a considerable correlation between genetic divergence and geographical distribution. Isolation due to complex mountain and desert geography might limit gene exchange between disjunct populations, resulting in high differentiation between geographical groups. (C) 2016 Elsevier Ltd.
