The complete chloroplast genome sequence of a new variety of Dendrobium officinale ‘zhong ke IV hao’

Abstract

Here, we reported and characterized the complete chloroplast (cp) genome sequence of Dendrobium officinale‘zhong ke IV hao’, a new variety from self-cross plants of imported Sichuan D. officinale, obtained exclusively using Illumina and PacBio sequencing technology. The genome size is 152,185 bp, containing a large single copy (LSC) region (85,094 bp) and a small single copy(SSC) region (14,521 bp) that were separated by two inverted repeat (IRs) regions (26,285 bp).The GC content was 37.46%. In total, the complete cp DNA contains 89 protein-coding genes, 30 tRNA genes, and 8 rRNA genes. Twelve genes contained one or two introns. Phylogenetic analyses showed that the chloroplast genome of D officinale ‘zhong ke IV hao’ is related to that of the traditional D.officinale.
