| Summary: | Anabasis aphylla is a salt and alkali resistant shrub grows in arid and semi-arid areas, which is also a constructive species of desert soil. To reveal the population structure and genetic diversity in populations of A. aphylla, a total of 106 samples were used as experimental materials for sequencing by specific-locus amplified fragment sequencing. In total, we obtained 300105 SNP which had high consistency. Phylogenetic tree of A. aphylla result showed there was a certain difference between these samples, which can be divided into two groups. The Shanon–Wiener index of A. aphylla was 0.4440 and the Nei diversity index was 0.2854. AMOVA analysis showed there was genetic differentiation among the seven groups to a certain level. The genetic diversity analysis showed the genetic variation of A. aphylla mainly from groups. This study provides a reference for further comprehensive study of the genetic structure and evolutionary adaptation of A. aphylla. |
