Characterization and phylogenetic analysis of the complete chloroplast genome of Curcuma zedoaria (Zingiberaceae)

Abstract

The first complete chloroplast genome of Curcuma zedoaria (Zingiberaceae) was reported in this study. The C. zedoaria chloroplast genome was 162,135 bp in length, and consisted of one large single-copy (LSC) region of 86,966 bp, one small single-copy (SSC) region of 15,737 bp, and a pair of inverted repeat (IR) regions 29,716 bp. It encoded 141 genes, including 87 protein-coding genes (79 PCG species), 46 tRNA genes (28 tRNA species), and 8 rRNA genes (4 rRNA species). The phylogenetic analysis based on single nucleotide polymorphisms strongly supported that C. zedoaria, Curcuma roscoeana, Curcuma longa, and Stahlianthus involucratus clustered together in group Curcuma II within the family Zingiberaceae.
