Single Nucleotide Polymorphism Markers Based on Hyper-Seq Revealed the Genetic Diversity and Genetic Relationship of Horsfieldia hainanensis in China
Horsfieldia hainanensis is China’s second-class key protected wild plant with high scientific research, timber, and medicinal values. In this study, the SNP molecular marker technology was used to determine the genetic diversity, genetic structure, genetic differentiation, genetic relationship, and its influencing factors of H. hainanensis populations. It provided a scientific basis for the formulation of its protection strategy. The results showed that (1) the genetic diversity of H. hainanensis populations exhibited a very low level (π = 0.0011). (2) The overall genetic differentiation of H. hainanensis populations was relatively large. There was a significant genetic differentiation between Hainan populations and Guangxi and Yunnan populations on the mainland (FST = 0.556); the genetic differentiation between Guangxi and Yunnan populations was relatively smaller (FST = 0.242). There is a natural water barrier around Hainan Island that reduces the gene exchange between island populations and mainland populations. Therefore, geographical isolation is one of the main factors affecting the genetic differentiation of H. hainanensis populations (p = 0.0103 < 0.05). (3) The genetic relationship between Hainan populations and Yunnan and Guangxi populations was relatively distant, while the genetic relationship between Yunnan and Guangxi populations was relatively closer. In conclusion, it is recommended that during in situ protection, the Guangxi population with higher genetic diversity should be preferentially protected, especially the populations in NG and SL should be regarded as the key protected populations of wild populations. The gene exchange between Yunnan population (MLP) and Guangxi populations (NG, SL, DX1, and DX2) should be enhanced by means of artificial pollination in different localities. During ex situ protection, the germplasm resource collection work of the population (NG, SL) with higher genetic diversity should be carried out preferentially. The technical research on tissue culture and rapid propagation should be actively carried out. A germplasm resource nursery should be established. The individuals should be planted according to provenance and family, but the planting distance between individuals can be appropriately reduced to increase the gene exchange between individuals and make up for the defects during in situ protection.
