【 摘 要 】

Paris polyphylla var. alba is a medicinal plant commonly used in the southwest of China. This study characterized the complete chloroplast (cp) genome sequence of P. polyphylla var. alba to investigate its phylogenetic relationship in Melanthiaceae. The cp genome of P. polyphylla var. alba is 165,079 base pairs (bp) in length with 36.96% G + C content. The cp genome is divided into (a) large single copy (LSC) (84,393 bp), (b) small single copy (SSC) (16,066 bp), and (c) two inverted regions (32,310 bp). The cp genome contains 135 genes, including 89 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis indicated that P. polyphylla var. alba is closest to P. polyphylla var. emeiensis, and Paris had a close relationship with Trillium in Melanthiaceae.
