A draft genome for Spatholobus suberectus

Spatholobus suberectus Dunn ( S . suberectus ), which belongs to the Leguminosae, is an important medicinal plant in China. Owing to its long growth cycle and increased use in human medicine, wild resources of S . suberectus have decreased rapidly and may be on the verge of extinction. De novo assembly of the whole S . suberectus genome provides us a critical potential resource towards biosynthesis of the main bioactive components and seed development regulation mechanism of this plant. Utilizing several sequencing technologies such as Illumina HiSeq X Ten, single-molecule real-time sequencing, 10x Genomics, as well as new assembly techniques such as FALCON and chromatin interaction mapping (Hi-C), we assembled a chromosome-scale genome about 798 Mb in size. In total, 748 Mb (93.73%) of the contig sequences were anchored onto nine chromosomes with the longest scaffold being 103.57 Mb. Further annotation analyses predicted 31,634 protein-coding genes, of which 93.9% have been functionally annotated. All data generated in this study is available in public databases.
