Chromosome-level genome assembly of the autotetraploid yellow pitaya provides novel insights into evolution of trait patterning in pitaya species with different ploidy

Chromosome-level genome assembly of the autotetraploid yellow pitaya provides novel insights into evolution of trait patterning in pitaya species with different ploidy

Abstract Background Yellow pitaya (Selenicereus megalanthus, 2n = 4x = 44) breeding remains severely hindered due to the lack of a reference genome. Results Here, we present a high-quality chromosome-level genome assembly of yellow pitaya using PacBio HiFi sequencing and Hi-C scaffolding technologie...
