| 英文摘要 | Hippophae rhamnoides ssp. sinensis is an ecologically and economically important species that has been widely used as a pioneer plant in China. In this study, we employed both nuclear ISSR and maternal cpSSR markers to survey the genetic diversity and structure of populations of ssp. sinensis representing three different landscapes, the northwestern desert and grassland region, the alpine vegetation region of the Qinghai-Tibetan Plateau, and the northeastern humid forest region. In all, 12 natural populations with a scattered distribution in the area were studied. The genetic diversities of populations were found to be uneven, and the total genetic diversity was low on the basis of both types of marker. Mantel tests based on both individual Euclidean distance matrices and population genetic distance (measured by I broken vertical bar pt) matrices showed that the two marker systems detected similar trends with respect to genetic distances between populations. The analysis of molecular variance (AMOVA) revealed significant differentiation among populations and among regions for both types of marker. Although the detected pattern of isolation-by-distance among all sampled populations confirmed the earlier colonization pathway, the low level of gene flow and the lack of isolation by distance within each region suggested the presence of an additional dispersal barrier. UPGMA dendrograms and PCA plots also revealed clear clustering and significant regional differentiation. Our results indicate that the genetic structure of ssp. sinensis has been affected by habitat fragmentation and restricted population sizes. We propose that the biology of reproduction and ecology have played determinant roles in the development of the regional structure of populations. The genetic information obtained will help to establish conservation strategies and programs for sustainable management of H. rhamnoides ssp. sinensis. |
