show Abstracthide AbstractThe wax gourd (Benincasa hispida), the only species in the genus Benincasa, is an important crop native to Asia that has been widely planted for multi-purpose uses. The first wax gourd draft genome was published three years ago, but it was incomplete and highly-fragmented due to data and technical limitations. Herein, we report a new chromosome-level genome assembly and annotation of B. hispida. We generated 974.87 Mb of unitigs with N50 size of 2.43 Mb via a hybrid assembly strategy by using PacBio long reads and Illumina short reads. We then connected them into scaffolds with Hi-C data, resulting 1862 scaffolds with total length of 975.62 Mb, and 94.92% of the length (926.05 Mb) is contained in the 12 largest scaffolds corresponding to the 12 chromosomes of B. hispida. We predicted 37,092 protein-coding genes, and 85.05% of them were functionally annotated.
