主 题：potato genome polyploid genome haplotype-resolved assembly haplotype diversity potato centromere
摘 要：Potato(Solanum tuberosum)is the most consumed non-cereal food *** commercial potato cultivars are autotetraploids with highly heterozygous genomes,severely hampering genetic analyses and *** leveraging the state-of-the-art sequencing technologies and polyploid graph binning,we achieved a chromosome-scale,haplotype-resolved genome assembly of a cultivated potato,Cooperation-88(C88).lntra-haplotype comparative analyses revealed extensive sequence and expression differences in this tetraploid *** identified haplotype-specific pericentromeres on chromosomes,suggesting a distinct evolutionary trajectory of potato homologous ***,we detected double reduction events that are unevenly distributed on haplotypes in 1021 of 1034 selfing progeny,a feature of autopolyploid *** distinguishing maternal and paternal haplotype sets in C88,we simulated the origin of heterosis in cultivated tetraploid with a survey of 3110 tetra-allelic loci with deleterious mutations,which were masked in the heterozygous condition bytwo *** study provides insights into the genomic architecture of autopolyploids and will guide their breeding.
