ABSTRACT

Domestication of orphan crops could be explored by editing their genomes. Genome editing has a lot of promise for enhancing agricultural output, and there is a lot of interest in furthering breeding in orphan crops, which are sometimes plagued with unwanted traits that resemble wild cousins. Consequently, applying model crop knowledge to orphan crops allows for the rapid generation of targeted allelic diversity and innovative breeding germplasm. We explain how plant breeders could employ genome editing as a novel platform to accelerate the domestication of semi-domesticated or wild plants, resulting in a more diversified base for future food and fodder supplies. This review emphasizes both the practicality of the strategy and the need to invest in research that advances our understanding of plant genomes, genes, and cellular systems. Planting more of these abandoned orphan crops could help alleviate food scarcities in the challenge of future climate crises.

摘要

可以通过编辑它们的基因组来探索孤儿作物的驯化。基因组编辑对提高农业产量有很大的希望，而且人们对进一步培育孤儿作物有很大兴趣，这些孤儿作物有时会受到类似于野生表亲的不需要的性状的困扰。因此，将模式作物知识应用于孤儿作物可以快速产生目标等位基因多样性和创新育种种质。我们解释了植物育种者如何将基因组编辑作为一个新平台来加速半驯化或野生植物的驯化，从而为未来的食物和饲料供应提供更加多样化的基础。这篇综述强调了该策略的实用性以及投资于促进我们对植物基因组、基因和细胞系统的理解的研究的必要性。
