The genome of the SunUp transgenic papaya cultivar includes a complex 1.64-Mb insertion that contains 3 transgenic fragments integrated with 61 nuclear genome fragments from the progenitor Sunset cultivar and 13 organelle genome fragments. Population genomic analyses yielded 147 selective sweeps during papaya domestication, which include essential genes that are involved in fruit flesh color formation and sugar content.
