Population genomics provides new insights into the genetic variation patterns, population demographic history, and high-altitude adaptation of Sophora moorcroftiana.

ABSTRACT:

Background

Sophora moorcroftiana, a key stone shrub in Xizang (Tibet), has significant ecological and economic value. However, its populations face severe degradation. Understanding key evolutionary drivers of genetic variation within and among populations is critical for conserving and managing this species. Previous studies indicate a strong genetic structure correlated with altitude, but limited knowledge exists about the drivers of its geographic structure and evolutionary history. To address this, we conducted genomic research on 225 samples from 15 populations of S. moorcroftiana.

Results

Populations of S. moorcroftiana exhibited distinct population structure, divided into four subpopulations. Subpopulation P1 (Gongbu Jiangda County, Nyingchi) showed the greatest genet
