title: The complete chloroplast genome of traditional Chinese medical plants Paris polyphylla var. yunnanensis.
abstract: Paris polyphylla var. yunnanensis is a perennial medical plant widely used in traditional Chinese medicine. Here, we report the complete chloroplast genome of P. polyphylla var. yunnanensis. The genome is 157 675 bp in length including a small single-copy region (SSC, 18 319 bp) and a large single-copy region (LSC, 84 108 bp) separated by a pair of inverted repeats (IRs, 27 624 bp). The genome contained 115 genes, including 81 protein-coding genes, 4 ribosomal RNA genes, and 30 tRNA genes. Among these genes, 13 harbored a single intron and 2 contained a couple of introns. The overall G + C content of the cpDNA is 37.4%, while the corresponding values of the LSC, SSC, and IR regions are 35.71%, 31.43%, and 41.87%, respectively. A Maximum-likelihood phylogenetic analysis suggested that genus Trillium, Paris, Fritillaria, and Lilium were strongly supported as monophyletic and the P. polyphylla var. yunnanensis is closely related to Trillium.
