The complete chloroplast genome of Dendrobium nobile, an endangered medicinal orchid from north-east India and its comparison with related Dendrobium species

Abstract

The medicinal orchid genus Dendrobium belonging to the Orchidaceae family is a huge genus comprising about 800–1,500 species. To better illustrate the species status in the genus Dendrobium, a comparative analysis of 33 available chloroplast genomes retrieved from NCBI RefSeq database was compared with that of the first complete chloroplast genome of D. nobile from north-east India based on next-generation sequencing methods (Illumina HiSeq 2500-PE150). Our results provide comparative chloroplast genomic information for taxonomical identification, alignment-free phylogenomic inference and other statistical features of Dendrobium plastomes, which can also provide valuable information on their mutational events and sequence divergence.
