Global food security depends heavily on a few staple crops, while orphan crops, despite being less studied, offer the potential benefits of environmental adaptation and enhanced nutritional traits, especially in a changing climate. Major crops have benefited from genomics-based breeding, initially using single genomes and later pangenomes. Recent advances in DNA sequencing have enabled pangenome construction for several orphan crops, offering a more comprehensive understanding of genetic diversity. Orphan crop research has now entered the pangenomics era and applying these pangenomes with advanced selection methods and genome editing technologies can transform these neglected species into crops of broader agricultural significance.
全球粮食安全在很大程度上依赖于少数几种主粮作物，而小众作物尽管研究较少，但具有环境适应性和增强营养特性等潜在益处，尤其是在气候变化的情况下。主要作物已从基于基因组学的育种中受益，最初是使用单个基因组，后来是泛基因组。DNA测序的最新进展使得能够构建几种小众作物的泛基因组，从而更全面地了解遗传多样性。小众作物研究现已进入泛基因组学时代，将这些泛基因组与先进的选择方法和基因组编辑技术相结合，可以将这些被忽视的物种转变为具有更广泛农业意义的作物。
