Genetic diversity and population structure of an insect-pollinated and bird-dispersed dioecious tree in a fragmented karst forest landscape.

This study combined population genetics and parentage analysis to obtain foundational data for the conservation of . . is a Class I tree species that occurs in two disjunct regions in a biodiversity hotspot in southwest China.

Phylogeographic analysis of in subtropical China provides insights into the origin of cultivated monk fruit and conservation of genetic resources.

, an economically important plant species with high medicinal value, is endemic to subtropical China. To determine the population structure and origin of cultivated , we examined the variation in three chloroplast DNA regions (RA, HA, LF) and two orthologous nuclear genes ( and ) of in 130 wild individuals (selected from 13 wild populations across its natural distribution range) and 21 cultivated individuals using a phylogeographic approach. The results showed three distinct chloroplast lineages, which were restricted to different mountain ranges, and strong plastid phylogeographic structure.
