The Complete Chloroplast Genome of Dendrobium nobile, an endangered medicinal orchid from Northeast India and its comparison with related chloroplast genomes of Dendrobium species

The medicinal orchid genus Dendrobium belonging to the Orchidaceae family is the largest genus comprising about 800-1500 species. To better illustrate the species status in the genus Dendrobium, a comparative analysis of 33 newly sequenced 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.
