Genomic insights into historical population dynamics, local adaptation, and climate change vulnerability of the East Asian Tertiary relict Euptelea (Eupteleaceae).

ABSTRACT: The warm-temperate and subtropical climate zones of East Asia are a hotspot of plant species richness and endemism, including a noticeable number of species-poor Tertiary relict tree genera. However, little is understood about when East Asian Tertiary relict plants diversified, how they responded demographically to past environmental change, and to what extent their current genomic composition (and adaptive capacity) might mitigate the effects of global warming. Here, we obtained genomic (RAD-SNP) data for 171 samples from two extant species of Euptelea in China (24 E. pleiosperma populations) and Japan (11 E. polyandra populations) to elucidate their divergence and demographic histories, genome-wide associations with current environmental variables, and genomic vulner
