Characterization of the complete plastid genome of the perennial herb Astragalus complanatus Bunge (Fabales: Fabaceae).

ABSTRACT: Astragalus complanatus Bunge is a perennial herb with high medicinal value, and is endemic to China. The plastid genome of A. complanatus was determined to be 124,213 bp in length with an A + T-biased nucleotide composition (65.7% A + T). The plastid genome harbors a total of 111 genes, including 75 protein-coding, 32 tRNA, and 4 rRNA genes. The presence of one or two introns was detected in 11 protein-coding genes and 6 tRNA genes. Phylogenetic analysis revealed that A. complanatus failed to cluster together with the seven congeners, implying that its phylogenetic placement may need further investigation.
