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.
