Phylogeography of two closely related species of Allium endemic to East Asia: Population evolution in response to climate oscillations
This study investigated the effects of climate oscillations on the evolution of two closely related Allium species, A. neriniflorum and A. tubiflorum. We sequenced three cp DNA (cpDNA) fragments (rps16, rpl32‐trnL, and trnD‐trnT, together approximately 2,500 bp in length) of two closely related Alli...

description | This study investigated the effects of climate oscillations on the evolution of two closely related Allium species, A. neriniflorum and A. tubiflorum. We sequenced three cp DNA (cpDNA) fragments (rps16, rpl32‐trnL, and trnD‐trnT, together approximately 2,500 bp in length) of two closely related Allium species, with samples from 367 individuals in 47 populations distributed across the total range of these species. The interspecific and intraspecific divergence times of the two species were in the Quaternary glaciation. The population divergence was high for the cpDNA variation, suggesting a significant phylogeographic structure (N(ST) = 0.844, G(ST) = 0.798, p < 0.05). Remarkable ecological differentiation was also revealed by Niche models and statistical analyses. Our results suggest the speciation event of the two species was triggered by violent climatic changes during the Quaternary glaciation. |
