Characterization and phylogenetic analysis of the complete chloroplast genome sequence of Costus viridis (Costaceae)

Abstract

The first complete chloroplast genome of Costus viridis (Costaceae) was reported in the current study. The C. viridis genome was 168,966 bp in length and comprised a pair of inverted repeat (IR) regions of 29,166 bp each, a large single-copy (LSC) region of 92,189 bp, and a small single-copy (SSC) region of 18,445 bp. It encoded 133 genes, including 87 protein-coding genes (79 PCG species), 38 tRNA genes (28 tRNA species), and eight rRNA genes (four rRNA species). The overall AT content was 63.75%. Phylogenetic analysis showed that C. viridis was closely related to species Costus osae within the genus Costus in family Costaceae.
