Astragalus is the largest flowering plant genus. We assembled the plastid genomes of four Astragalus species (Astragalus iranicus, A. macropelmatus, A. mesoleios, A. odoratus) using next-generation sequencing and analyzed their plastomes including genome organization, codon usage, nucleotide diversity, prediction of RNA editing and etc. The total length of the newly sequenced Astragalus plastomes ranged from 121,050 bp to 123,622 bp, with 110 genes comprising 76 protein-coding genes, 30 transfer RNA (tRNA) genes and four ribosome RNA (rRNA) genes. Comparative analysis of the chloroplast genomes of Astragalus revealed several hypervariable regions comprising three non-coding sites (trnQ(UUG)-accD, rps7 -trnV(GAC) and trnR(ACG)-trnN(GUU)) and four protein-coding genes (ycf1, ycf2, accD and clpP), which have potential as molecular markers. Positive selection signatures were found in five genes in Astragalus species including rps11, rps15, accD, clpP and ycf1. The newly sequenced species, A. macropelmatus, has an approximately 13-kb inversion in IR region. Phylogenetic analysis based on 75 protein-coding gene sequences confirmed that Astragalus form a monophyletic clade within the tribe Galegeae and Oxytropis is sister group to the Coluteoid clade. The results of this study may helpful in elucidating the chloroplast genome structure, understanding the evolutionary dynamics at genus Astragalus and IRLC levels and investigating the phylogenetic relationships. Moreover, the newly plastid genomes sequenced have been increased the plastome data resources on Astragalus that can be useful in further phylogenomic studies.
