The complete chloroplast genome and phylogenetic analysis of Astragalus sinicus Linne 1767

Abstract

Astragalus sinicus Linne 1767 is a traditional winter-growing green manure, that plays an important role in upgrading soil fertility and maintaining crop yield and quality for rice fields. This study reports the complete chloroplast genome of A. sinicus. The chloroplast genome contained 110 complete genes, including 76 protein-coding genes, 4 ribosomal RNA genes, and 30 tRNA genes with 123,830 bp in length and a 34.66% GC content with IR loss. The evolutionary history, referred to as the maximum-likelihood (ML), showed that A. sinicus and Astragalus bhotanensis were most closely related. The chloroplast genome analysis of A. sinicus will serve as a reference for future studies on species evolution, plant conservation, and molecular phylogeny in Astragalus.
