Next-generation sequencing-based population genetics unravels the evolutionary history of Rhodomyrtus tomentosa in China.

ABSTRACT:

Background

Rhodomyrtus tomentosa (Ait.) Hassk. is useful for its ornamental, medicinal, and ecological characteristics, and is considered a "Neglected and Underutilized Crop Species". However, our understanding of the geographic structure and evolutionary history of its wild populations is limited. To address this gap, we investigated genomic data from 284 samples of R. tomentosa from 28 wild populations in southern China.

Results

The genetic diversity of populations in different regions revealed the similar trends using whole-genome and RAD-seq data, and Hainan Island having a higher genetic diversity than other regions. The 28 populations clustered into three distinct groups: (a) GROUP1 on the eastern mainland within Guangdong, Fujian, and Hunan Provinces; (b) GROUP2 on th
