Abstract:
Curcuma longa L. is a widely distributed medicinal plant in Southeast Asia, especially in China. In this study, we reported and characterized the complete chloroplast genome sequence of C. longa. The chloroplast genome was determined to be 162,255 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 86,975 bp and 15,776 bp, respectively, which were separated by a pair of 29,752 bp inverted repeat (IR) regions. The genome is predicted to contain 133 genes, including 87 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 36.2%. A phylogenetic tree reconstructed by 23 chloroplast genomes reveals that C. longa is mostly related to Curcuma roscoeana, with bootstrap support values of 100%.
