| 英文摘要 | The hengduan mountains are the core region of the himalaya hotspot, and are renowned for their high levels of endemism. gentiana atuntsiensis and g. striolata are two closely related and morphologically similar species endemic to this region. in this study, inter-simple sequence repeat (issr) markers were used to investigate the genetic structure within these two species, as well as the differentiation between them. an analysis of molecular variance-derived estimate demonstrated only 13.5% of genetic differentiation between the two species. considering their adjacent distribution patterns, low genetic divergence, and clear clustering into two groups, it is hypothesized that the two species arose from a rapid and recent speciation event induced mainly by geographical isolation. a relatively high level of genetic diversity was revealed in each species (shannon's index of diversity: h(sp) = 0.324 and 0.391; h(pop) = 0.225 and 0.274; for g. atuntsiensis and g. striolata, respectively). most of the genetic variation was partitioned within populations (o(st) = 0.232 and 0.226 in g. atuntsiensis and g. striolata, respectively). the large population sizes, outcrossing breeding system, and small, light seeds that disperse widely may explain the genetic structure in both species.
