-Gene flow between diverging lineages challenges the resolution of species boundaries and the understanding of evolutionary history in recent radiations. Here, we integrate phylogenetic and coalescent tools to resolve reticulate patterns of...
Biased Gene Introgression and Adaptation in the Face of Chloroplast Capture in Aquilegia amurensis [0.03%]
向日葵萼中的基因 introgression 和适应面对氯代嘧啶捕获在Aquilegia amurensis中的情况

Huaying Wang et al.
-Chloroplast capture, a phenomenon that can occur through interspecific hybridization and introgression, is frequently invoked to explain cytonuclear discordance in plants. However, relatively few studies have documented the mechanisms of c...
