Dalbergia odorifera is a critically endangered tree species with high economic and medicinal value. In this study, its chloroplast genome was characterized using next generation Illumina pair-end sequencing dataset. The chloroplast genome has a quadripartite structure with 156,064 bp in length and contains a pair of 25,702 bp inverted repeat (IR) regions, which were separated by the large single copy (LSC: 85,805 bp) region and small single copy (SSC: 18,856 bp) region. The plastid genome harbors 111 unique genes, including 77 protein-coding genes (PCGs), 30 tRNAs and 4 rRNAs. The overall GC content of the whole genome was 36.1%. The Phylogenetic analysis showed a close relationship between D. odorifera and Arachis hypogaea species of Dalbergieae in our sampled species. The complete chloroplast genome provides fundamental information for genetic and conservation studies of D. odorifera.
