The MADS-box transcription factor (TF) gene family is pivotal in various aspects of plant biology, particularly in growth, development, and environmental adaptation. It comprises Type I and Type II categories, with the MIKC-type subgroups playing a crucial role in regulating genes essential for both the vegetative and reproductive stages of plant life. Notably, MADS-box proteins can influence processes such as flowering, fruit ripening, and stress tolerance. Here, we provide a comprehensive overview of the structural features, evolutionary lineage, multifaceted functions, and the role of MADS-box TFs in responding to biotic and abiotic stresses. We particularly emphasize their implications for crop enhancement, especially in light of recent advances in understanding the impact on sugarcane ( spp.), a vital tropical crop. By consolidating cutting-edge findings, we highlight potential avenues for expanding our knowledge base and enhancing the genetic traits of sugarcane through functional genomics and advanced breeding techniques. This review underscores the significance of MADS-box TFs in achieving improved yields and stress resilience in agricultural contexts, positioning them as promising targets for future research in crop science.
MADS盒转录因子（TF）基因家族在植物生物学的各个方面都起着关键作用，特别是在生长、发育和环境适应方面。它包括I型和II型类别，其中MIKC型亚组在调节植物生命周期营养和生殖阶段所必需的基因方面发挥着至关重要的作用。值得注意的是，MADS盒蛋白可以影响开花、果实成熟和抗逆性等过程。在这里，我们全面概述了MADS盒转录因子的结构特征、进化谱系、多方面功能以及它们在应对生物和非生物胁迫中的作用。我们特别强调它们对作物改良的影响，尤其是鉴于最近在理解对甘蔗（ spp.）的影响方面取得的进展，甘蔗是一种重要的热带作物。通过整合前沿研究结果，我们突出了通过功能基因组学和先进育种技术扩展我们的知识库以及改善甘蔗遗传性状的潜在途径。这篇综述强调了MADS盒转录因子在农业环境中提高产量和抗逆性方面的重要性，使其成为作物科学未来研究的有希望的目标。
