Isolation effects and soil properties drive genetic differentiation in Ormosia microphylla populations.

ABSTRACT: The genetic characteristics of six wild populations of Ormosia microphylla were investigated and their soil properties were analyzed by using Hyper-seq sequencing technology. Based on the findings, targeted protection strategies are proposed. Genetic diversity analysis revealed moderate overall genetic diversity of O. microphylla populations, with the ZD showing the highest and the JX the lowest genetic diversity. Compared to the populations outside the tiankeng, the LY, located in a Karst tiankeng, exhibited lower genetic diversity. This reduced genetic diversity of LY was possibly influenced by the combined influence of selective pressures unique to the tiankeng environment as well as the founder effect. Genetic structure analysis further indicated that the optimal number of clusters for
