Characterization and phylogenetic analysis of the complete chloroplast genome of Amaranthus viridis (Amaranthaceae)

Abstract

Amaranthus viridis is an important medicinal herb. In this study, the complete chloroplast genome (plastome) of A. viridis was repotred. It was a circular molecular of 150,452 bp in length and consists of a large single-copy region (LSC, 83,832 bp), a small single-copy region (SSC, 17,914 bp), and two inverted repeats (IRs, 24,353 bp for each) regions. The overall GC content was 36.6%. This plastome encodes 113 unique genes, including 79 protein-coding genes, 30 tRNAs, and four rRNAs. The phylogenetic tree of 18 Amaranthaceae chloroplast genomes supported that A. viridis was closely related to A. hybridus.
