Complete chloroplast genome sequence of Pedicularis cheilanthifolia, an alpine plant in China

Abstract

Pedicularis cheilanthifolia is an ecologically important species in alpine meadows of central and western China. In this study, the complete chloroplast genome (cpDNA) sequence of P. cheilanthifolia was characterized using Illumina pair-end sequencing. The cpDNA is 155,159 bp in length, and contains a pair of 25,966 bp inverted repeats (IR), one large single copy (LSC) region of 85,256 bp, and one small single copy (SSC) region of 17,971 bp. It contains 133 genes including 87 protein-coding genes (79 PCG species), 8 ribosomal RNA genes (4 RNA species), 37 transfer RNA genes (30 tRNA species) and 1 pseudogene (ndhF). The overall AT content of the whole genome is 62.3%, and the corresponding values of the LSC, SSC and IR regions are 64.3, 68.4 and 57.0%, respectively. Phylogenetic analysis based on ten chloroplast genomes indicates that P. cheilanthifolia is closely related to Castilleja paramensis.
