Characterization of the complete chloroplast genome ofZingiber zerumbet

Different species of Zingiberaceae are very similar in appearance, which brings some obstacles in the accurate identification of species. Here, we assembled and analyzed the complete chloroplast (cp) genome ofZingiber zerumbet. The cp genome ofZ. zerumbetis 169,183 bp in length, which contains a pair of inverted repeated (IR) regions of 37,480 bp, a large single copy (LSC) region of 86,709 bp, and a small single copy (SSC) region of 7,515 bp. The genome contains a total of 138 genes, including 92 protein-coding genes, 38 transfer RNA genes, and eight ribosomal RNA genes. Phylogenetic analysis exhibited that the cp genome sequence could distinguishZ. zerumbetfrom other species. This study is beneficial to the germplasm identification and utilization ofZ. zerumbet.
