Abstract

As critical transcription factors regulating various life activities, MADS-box transcription factors have been demonstrated to play key roles in controlling crop growth, development, and organogenesis. However, their relationship with crop yield has been seldom summarized. This article reviews the molecular mechanisms and genetic networks by which MADS-box transcription factors influence rice yield through regulating seed development, spikelet number, root nitrogen uptake, and environmental adaptability. Additionally, this review presents case studies on the application of favorable alleles within the MADS family genes in breeding practices. It also discusses how to integrate traditional breeding methods with emerging biotechnologies to overcome the adverse effects of linkage disequilibrium and pleiotropy in quantitative traits, aiming to achieve high yield, high quality, and stress-resistant breeding targets. Exploring and utilizing the molecular mechanisms of MADS-box transcription factors in rice yield regulation can significantly enhance crop productivity and ensure global food security.

MADS-box转录因子在水稻生长发育和环境胁迫中的调控机制

作为调控多种生命活动的关键转录因子，MADS-box转录因子已被证明在控制作物生长发育和器官发生中发挥关键作用。然而，它们与作物产量的关系很少得到总结。本文综述了MADS-box转录因子通过调控种子发育、小穗数、根系氮吸收和环境适应性等途径影响水稻产量的分子机制和遗传网络。此外，本文还介绍了MADS家族基因中有利等位基因在育种实践中的应用。探讨了如何将传统育种方法与新兴生物技术相结合，克服数量性状连锁不平衡和多效性的不利影响，实现高产、优质、抗逆性的育种目标。探索和利用MADS-box转录因子在水稻产量调控中的分子机制，可以显著提高作物生产力，保障全球粮食安全。
