Localized environmental heterogeneity drives the population differentiation of two endangered and endemic Opisthopappus Shih species.

ABSTRACT:

Background

Climate heterogeneity not only indirectly shapes the genetic structures of plant populations, but also drives adaptive divergence by impacting demographic dynamics. The variable localized climates and topographic complexity of the Taihang Mountains make them a major natural boundary in Northern China that influences the divergence of organisms distributed across this region. Opisthopappus is an endemic genus of the Taihang Mountains that includes only two spatially partitioned species Opisthopappus longilobus and Opisthopappus taihangensis. For this study, the mechanisms behind the genetic variations in Opisthopappus populations were investigated.

Results

Using SNP and InDel data coupled with geographic and climatic information, significant genetic differentiation
