Abstract

De-domestication or feralization is an interesting phenomenon in crops and livestock. Previously, evidence for crop de-domestication was based mainly on studies using phenotypic and genotypic data from limited molecular markers or gene segments. Recent genomic studies in rice, barley, and wheat provide comprehensive landscapes of de-domestication on a whole-genome scale. Here, we summarize crop de-domestication processes, ecological roles of de-domesticates, mechanisms underlying crop de-domestication syndromes, and conditions potentially favoring de-domestication events. We further explain how recent de-domestication studies have expanded our understanding of the complexity of crop evolution, and highlight the genetic novelties of de-domesticates beneficial for modern crop breeding.

Keywords: crop evolution; de-domestication; population genomics; shattering.
