摘要： A high royal jelly-producing strain of honeybees (HRJHB) has been obtained by successive artificial selection of Italian honeybees (Apis mellifera ligustica) in China. The HRJHB can produce amounts of royal jelly that are dozens of times greater than their original counterparts, which has promoted China to be the largest producer of royal jelly in the world. In this study, we generated a chromosome-scale of the genome sequence for the HRJHB using PacBio long reads and Hi-C technique. The genome consists of 16 pseudo-chromosomes that contain 222 Mb of sequence, with a scaffold N50 of 13.6 Mb. BUSCO analysis yielded a completeness score of 99.3%. The genome has 12,288 predicted protein-coding genes and a rate of 8.11% of repetitive sequences. One chromosome inversion was identified between the HRJHB and the closely related Italian honeybees through whole-genome alignment analysis. The HRJHB's genome sequence will be an important resource for understanding the genetic basis of high levels of royal jelly production, which may also shed light on the evolution of domesticated insects.
