Genome assembly of cultivated Jujube (Shiguang)

Jujube (Ziziphus jujube Mill.) is a valuable tree species with economic, edible, medicinal, and ecological conservation benefits. In this study, we used PacBio HiFi sequencing and Hi-C technology to assemble chromosome-level genomes of two cultivated Jujubes, namely Lingwuchangzao and Shiguang. The genome sizes of Lingwuchangzao and Shiguang were 385.66 Mb and 394.12 Mb, respectively, with contig N50 sizes of 30.62 Mb and 4.30 Mb. These genomes contained 31,082 and 31,015 protein-coding genes, and had repeat element contents of 42.11% and 42.33%, respectively. In summary, the assembly of two cultivated jujube genomes provide valuable genetic information for Jujube evolution, functional genomics research, and molecular breeding.
