Abstract

Dendrobium comatum is a rare orchid plant. To further its research and conservation, we reported and characterized its complete chloroplast (cp) genome by using Illumina paired-end sequencing data. We also analyzed its characteristics and studied its clustering relationships. The total chloroplast genome size was 158,008 bp, including inverted repeats (IRs) of 27,032 bp separated by a large single copy (LSC) region and a small single copy (SSC) region of 85,592 and 18,352 bp, respectively. A total of 132 genes, including 38 tRNA, 8 rRNA, and 87 protein-coding genes, were identified. Phylogenetic analysis showed that D. comatum is sister to D. kingianum with sufficient support.

Keywords: Dendrobium comatum; chloroplast genome; high-throughput sequencing; phylogenomic analysis.
