摘 要：Feralization is an important evolutionary process,but the mechanisms behind it remain poorly ***,we use the ancient fiber crop ramie(Boehmeria nivea(L.)Gaudich.)as a model to investigate genomic changes associated with both domestication and *** first produced a chromosome-scale de novo genome assembly of feral ramie and investigated structural variations between feral and domesticated ramie ***,we gathered 915 accessions from 23 countries,comprising cultivars,major landraces,feral populations,and the wild *** on whole-genome resequencing of these accessions,we constructed the most comprehensive ramie genomic variation map to ***,demographic,and admixture signal detection analyses indicated that feral ramie is of exoferal or exo-endo origin,i.e.,descended from hybridization between domesticated ramie and the wild progenitor or ancient *** ramie has higher genetic diversity than wild or domesticated ramie,and genomic regions affected by natural selection during feralization differ from those under selection during *** analyses showed that feral and domesticated ramie have similar ecological niches that differ substantially from the niche of the wild progenitor,and three environmental variables are associated with habitat-specific adaptation in feral *** findings advance our understanding of feralization,providing a scientific basis for the excavation of new crop germplasm resources and offering novel insights into the evolution of feralization in nature.
