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

Abstract

<i>Pinellia ternata</i> (Thunb.) Breit is one of the commonly used traditional Chinese medicine with tuber as medicine. We report herein the complete chloroplast genome sequence of <i>Pinellia ternata</i> (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, <i>Pinellia ternata</i> is sister to <i>Pinellia pedatisecta</i> and clustered within the group consisting of the species that belong to Araceae.
