Comparative studies on population genetic structure of two closely related selfing and outcrossing Zingiber species in Hainan Island.

Abstract excerpt

How mating system impacts the genetic diversity of plants has long fascinated and puzzled evolutionary biologists. Numerous studies have shown that self-fertilising plants have less genetic diversity at both the population and species levels than outcrossers. However, the phylogenetic relationships between species and correlated ecological traits have not been accounted for in these previous studies. Here, we...
