What is Genetic diversity and structure of the endemic and endangered species Aristolochia delavayi growing along the Jinsha River about?
The traditional medicinal plant, and endangered species __Aristolochia delavayi__ (Aristolochiaceae) is an endemic species in China and occurs in the warm and dry areas along the Jinsha river. It is also a specific host of the larvae of __Byasa daemonius__, a vulnerable butterfly. In this study, 15 pairs of polymorphic microsatellite primers of __A. delavayi__ were designed and screened based on the Simple Sequence Repeats (SSR) loci found by using the results of genome skimming. Based on these 15 SSR markers, the genetic diversity and structure of 193 individuals from ten natural populations were analyzed in detail. In comparison to other endemic and endangered plants in the region, the population of __A. delavayi__ possess a relatively high genetic diversity (__H__e = 0.550__, I__ = 1.112). AMOVA analysis showed that 68.4% of the total genetic diversity was within populations and 31.6% of the variation occurred among populations. There was a significant genetic differentiation among natural populations of __A. delavayi__ detectable, with low gene flow (__N__m = 0.591). This might be attributed to geographical barriers and limited seed dispersal__.__ To test the isolation by dista
