Complete chloroplast genome sequence of Pinellia ternata (Thunb.) Breit, a medicinal plants to China

摘要

Pinellia ternata (Thunb.) Breit is one of the commonly used traditional Chinese medicine with tuber as medicine. We report herein the complete chloroplast genome sequence of Pinellia ternata (Thunb.) Breit. It is length of 167,280?bp, which contained a small single-copy (SSC) region of 23,618?bp and a large single-copy (LSC) region of 92,450?bp, separated by two copies of an inverted repeat (IR) of 25,606?bp. The chloroplast genome contains 113 unique genes, including 79 PCG, 4 rRNA genes, and 30 tRNA genes. In addition, 19 genes contained one or two introns, which of those including 13 PCG genes possess a single intron and 2 PCG genes harbor two introns; and 6 tRNA genes harbor a single intron. In this study, Pinellia ternata is sister to Pinellia pedatisecta and clustered within the group consisting of the species that belong to Araceae.
