Despite their economic importance and well-characterized domestication syndrome,the genomic impact of domestication and the identification of variants underlying the domestication traits in Cucurbita species(pumpkins and squashes)is currently *** argyrosperma,also known as cushaw pumpkin or silver-seed gourd,is a Mexican crop consumed primarily for its seeds rather than fruit *** makes it a good model to study Cucurbita domestication,as seeds were an essential component of early Mesoamerican diet and likely the first targets of human-guided selection in pumpkins and *** obtained population-level data using tunable Genotype by Sequencing libraries for 192 individuals of the wild and domesticated subspecies of *** across *** also assembled the first high-quality wild Cucurbita *** genomic analyses revealed several structural variants and presence/absence of genes related to *** results indicate a monophyletic origin of this domesticated crop in the lowlands of *** found evidence of gene flow between the domesticated and wild subspecies,which likely alleviated the effects of the domestication *** uncovered candidate domestication genes that are involved in the regulation of growth hormones,plant defense mechanisms,seed development,and *** presence of shared selected alleles with the closely related species Cucurbita moschata suggests domestication-related introgression between both taxa.
