Description
A haplotype resolved genome assembly for the dioecious watermelon relative Citrullus naudinianus was generated using PacBio HiFi and Hi-C sequencing technologies.  Shotgun sequence reads from male and female plants were mapped to the genome to facilitate identification of the sex determination system (XY or ZW) and the extent of the non-recombining sex determination region. We explore whether orthologs of genes influenicng male and female flower sex determination in monoecious Citrullus species including watermelon (C. lanatus) are sex-linked in C. naudinianus.
