The complete chloroplast genome sequences of a highly Endangered orchid species Paphiopedilum barbigerum (Orchidaceae)

Abstract

Paphiopedilum barbigerum (Orchidaceae) is an endangered species with highly ornamental and horticultural value. The chloroplast genome of the species was assembled using next-generation sequencing method. The complete cp genome sequence is 156,329 bp in length, comprising a pair of inverted repeat regions (IRs) of 34,214 bp each, separated by a large single-copy (LSC) region of 86056 bp, and a small single-copy (SSC) region of 1845 bp. The chloroplast genome contains 126 functional genes, including 80 protein-coding genes (PCGs), 38 tRNA genes, and 8 rRNA genes. The phylogenetic position of the species based on the complete cp genome was also inferred in this study.
