A chromosome-level genome assembly of the eggplant GUIQIE-1

The eggplant (Solanum melongena L.) is one of the most important crops belonging to the family Solanaceae, ranking third in total production and economic value in the genus Solanum. Here, we report a high-quality, chromosome-scale eggplant reference genome,which was assembled by combining PacBio long reads and Hi-C sequencing data. The genome assembly had a total length of 1,155.8Mb and a contig N50 length of 5.3 Mb. According to the Hi-C data, 97.1% of the assembled bases were anchored into 12 pseudochromosomes. Repetitive sequences occupied 70.1% of the assembly length, and 35,018 high-confidence protein-coding genes were annotated based on multiple evidence. The eggplant reference genome sequence will not only facilitate evolutionary studies in the Solanaceae family but also facilitate their breeding and improve productivity.
