Crop biodiversity is one of the major inventions of humanity through the process of domestication. It is also an essential resource for crop improvement to adapt agriculture to ever-changing conditions like global climate change and consumer preferences. Domestication and the subsequent evolution under cultivation have profoundly shaped the genetic architecture of this biodiversity. In this review, we highlight recent advances in our understanding of crop biodiversity. Topics include the reduction of genetic diversity during domestication and counteracting factors, a discussion of the relationship between parallel phenotypic and genotypic evolution, the role of plasticity in genotype × environment interactions, and the important role subsistence farmers play in actively maintaining crop biodiversity and in participatory breeding. Linking genotype and phenotype remains the holy grail of crop biodiversity studies.

作物生物多样性:未完成的大自然巨著

作物生物多样性是人类在驯化过程中的重大发明之一。它也是作物改良的重要资源,使农业适应全球气候变化和消费者偏好等不断变化的条件。驯化和随后的栽培进化深刻地塑造了这种生物多样性的遗传结构。在这篇评论中,我们重点介绍了我们对作物生物多样性理解的最新进展。主题包括驯化过程中遗传多样性的减少和抵消因素,讨论平行表型和基因型进化之间的关系,可塑性在基因型×环境相互作用中的作用,以及自给农民在积极维护作物生物多样性和参与性方面的重要作用配种。
