Primula sp Ideal mode
.

The researchers took the Primula vulgaris complex as the research object, analyzed the genetic structure, phylogenetic relationship, population history and gene flow of the complex using whole-genome resequencing data, analyzed the characteristics of the species’ gene composition, and discussed the special features.
The genomic mechanism of soil habitat adaptability and speciation
.

Population genome analysis showed that there is historical gene flow among the multiple species of Primula vulgaris complex.
Gene flow and linkage selection have a role in shaping the genetic differentiation of the genome, but it mainly acts on the non-highly differentiated regions of the genome; and ancestral polymorphisms Sorting plays a decisive role in the formation of highly differentiated regions of the genome
.

According to reports, the Primula vulgaris genus Primula vulgaris complex includes 5 recently differentiated species, all of which are uniquely distributed in the Nanling Mountains, among which Primula vulgaris, Hunan Primula vulgaris, and Polychromatic Primula The primula vulgaris and the pale yellow primula vulgaris are unique species in the karst soil habitat, while the primula vulgaris Suichuan is a unique species in the Danxia landform habitat
.

This research provides a comprehensive analysis on the genomics level of the species formation and diversity evolution of the special soil habitats in the Nanling Mountains, and lays the foundation for a deeper understanding of the formation mechanism of biodiversity in the region
