Supporting data for "The chromosome-level draft genome of <i>Dalbergia odorifera</i>"

<i>Dalbergia odorifera</i> T. Chen (Fabaceae) is an IUCN red-listed tree. This tree is of high medicinal and commercial value due to its officinal, insect-proof, durable heartwood. However, there is a lack of genome reference, which has hindered the development of studies on heartwood formation. <br>We presented the first chromosome-scale genome assembly of <i>D. odorifera</i> obtained based on Illumina paired-end sequencing, Pacific Bioscience single-molecule real-time sequencing, 10x Genomics linked-reads, and Hi-C technology. We assembled 97.68% of the 653.45 Mb <i>D. odorifera</i> genome with scaffold N50 and contig sizes of 56.16 Mb and 5.92 Mb, respectively. Ten super-scaffolds corresponding to the 10 chromosomes were assembled with the longest scaffold reaching 79.61 Mb. Repetitive elements account for 54.17% of the genome, and 30,310 protein-coding genes were predicted from the genome, of which approximately 92.6% were functionally annotated. The phylogenetic tree showed that <i>D. odorifera</i> diverged from the ancestor of <i>A. thaliana</i> and <i>P. trichocarpa</i>, and then separated from <i>G. max</i> and <i>C. cajan</i>. <br>We sequence and reveal the first chromosome-level de novo genome of <i>D. odorifera</i>. These studies provide valuable genomic resources for the research of heartwood formation in <i>D. odorifera</i> and other timber trees. The high-quality assembled genome can also be used as a reference for comparative genomics analysis and future population genetic studies of <i>D. odorifera</i>.
