Comparative evolutionary history of two closely related desert plant, Convolvulus tragacanthoide and Convolvulus gortschakovii (Convolvulaceae) from northwest China.

ABSTRACT: Desert ecosystems are one of the most fragile ecosystems on Earth. The study of the effects of paleoclimatic and geological changes on genetic diversity, genetic structure, and species differentiation of desert plants is not only helpful in understanding the strategies of adaptation of plants to arid habitats, but can also provide reference for the protection and restoration of vegetation in desert ecosystem. Northwest China is an important part of arid regions in the northern hemisphere. Convolvulus tragacanthoides and Convolvulus gortschakovii are closely related and have similar morphology. Through our field investigation, we found that the annual precipitation of the two species distribution areas is significantly different. Thus, C. tragacanthoides and C
