Abstract

Lanxangia tsaoko is a famous Chinese traditional medicine with long history. In this study, the complete chloroplast (cp) genome of L. tsaoko was characterized and assembled using a high-throughput sequencing method. The complete cp genome is 164,008 bp in length, including a large single copy (LSC) region of 89,134 bp and a small single copy (SSC) region of 15,372 bp separated by two inverted repeat (IR) regions of 29,751 bp. A total of 137 genes were identified, including 88 protein-coding genes (PCG), 38 transfer RNA genes, 8 ribosomal RNA genes, and 3 pseudogenes. The phylogenetic analysis revealed that L. tsaoko is located in Zingiberaceace, closely related to Amomum and Alpinia with a 100% bootstrap support.

Keywords: Lanxangia tsaoko; complete chloroplast genome; phylogenetic analysis; traditional Chinese medicine.
