Sustainable agricultural production largely depends upon the viability and longevity of high-quality seeds during storage. Legumes are considered as rich source of dietary protein that helps to ensure nutritional security, but associated with poor seed longevity that hinders their performance and productivity in farmer's fields. Seed longevity is the key determinant to assure proper seed plant value and crop yield. Thus, maintenance of seed longevity during storage is of prime concern and a pre-requisite for enhancing crop productivity of legumes. Seed longevity is significantly correlated with other seed quality parameters such as germination, vigor, viability and seed coat permeability that affect crop growth and development, consequently distressing crop yield. Therefore, information on genetic basis and regulatory networks associated with seed longevity, as well as molecular dissection of traits linked to longevity could help in developing crop varieties with good storability. Keeping this in view, the present review focuses towards highlighting the molecular basis of seed longevity, with special emphasis on candidate genes and proteins associated with seed longevity and their interplay with other quality parameters. Further, an attempt was made to provide information on 3D structures of various genetic loci (genes/proteins) associated to seed longevity that could facilitate in understanding the interactions taking place within the seed at molecular level. This review compiles and provides information on genetic and genomic approaches for the identification of molecular pathways and key players involved in the maintenance of seed longevity in legumes, in a holistic manner. Finally, a hypothetical fast-forward breeding pipeline has been provided, that could assist the breeders to successfully develop varieties with improved seed longevity in legumes.
可持续农业生产在很大程度上取决于高质量种子在储存期间的活力和寿命。豆类被认为是膳食蛋白质的丰富来源，有助于确保营养安全，但种子寿命较短，这阻碍了它们在农民田间的表现和生产力。种子寿命是确保种子适当种植价值和作物产量的关键决定因素。因此，在储存期间维持种子寿命是首要关注的问题，也是提高豆类作物生产力的先决条件。种子寿命与其他种子质量参数如发芽率、活力、活力和种皮通透性显著相关，这些参数会影响作物的生长和发育，从而影响作物产量。因此，了解与种子寿命相关的遗传基础和调控网络，以及对与寿命相关的性状进行分子剖析，有助于培育出具有良好耐贮性的作物品种。鉴于此，本综述着重强调种子寿命的分子基础，特别关注与种子寿命相关的候选基因和蛋白质，以及它们与其他质量参数的相互作用。此外，还尝试提供与种子寿命相关的各种遗传位点（基因/蛋白质）的三维结构信息，这有助于从分子水平理解种子内部发生的相互作用。本综述全面汇编并提供了有关遗传和基因组方法的信息，用于鉴定参与维持豆类种子寿命的分子途径和关键因素。最后，提供了一个假设的快速育种流程，可协助育种者成功培育出豆类种子寿命得到改善的品种。
