Genomic insights into the evolutionary history and conservation of the living fossil <i>Tetracentron sinense</i>.

ABSTRACT: Tetracentron sinense is a 'living fossil' tree in East Asia. Understanding how this 'living fossil' responds to climate change and adapts to local environments is critical for its conservation. Here, we used re-sequenced genomes to clarify the evolutionary history and adaptive potential of T. sinense. We identified six divergent lineages in T. sinense: three lineages from southwestern China (Yunnan Province) and three lineages from the central subtropical region of China. Additionally, we detected hybridization events between some adjacent lineages. Demographic analysis revealed that over the past 10,000 years the effective population size (Ne) of three T. sinense lineages (i.e., NORTH, SWEST, and YNWEST) increased after their last bottleneck and t
