Abstract

Crop domestication is a fascinating area of study, as shown by a multitude of recent reviews. Coupled with the increasing availability of genomic and phenomic resources in numerous crop species, insights from evolutionary biology will enable a deeper understanding of the genetic architecture and short-term evolution of complex traits, which can be used to inform selection strategies. Future advances in crop improvement will rely on the integration of population genetics with plant breeding methodology, and the development of community resources to support research in a variety of crop life histories and reproductive strategies. We highlight recent advances related to the role of selective sweeps and demographic history in shaping genetic architecture, how these breakthroughs can inform selection strategies, and the application of precision gene editing to leverage these connections.

摘要

作物驯化是一个引人入胜的研究领域,最近的大量评论也证明了这一点。随着越来越多的基因组和表型资源在众多作物物种中得到应用,进化生物学的见解将使人们能够更深入地了解复杂性状的遗传结构和短期进化,从而为选择策略提供信息。未来作物改良的进展将依赖于群体遗传学与植物育种方法的结合,以及社区资源的开发,以支持各种作物生活史和生殖策略的研究。我们强调了与选择清除和人口历史在塑造遗传结构中的作用相关的最新进展,这些突破如何为选择策略提供信息,以及精确基因编辑在利用这些联系方面的应用。
