Characterization and phylogenetic analysis of the complete chloroplast genome sequence of Dendrobium hainanense (Orchidaceae)

Abstract

In this study, we report the chloroplast (cp) genome of Dendrobium hainanense . The cp genome was 151,367 bp in length; the overall CG content of the genome was 37.46%. The length of the large single-copy (LSC) region was 83,938 bp, and 15,829 bp in a small single-copy (SSC) region, and a pair of inverted repeats (IRs) of 12,900 bp. One hundred and twenty-seven genes were predicted, including 81 protein-coding genes, 38 genes for tRNA, and eight genes for rRNA. The results of phylogenetic tree showed that Dendrobium hainanense had the closest genetic relationship with Dendrobium parciflorum . This study will be help to understand the genetic diversity of Dendrobium .
