Evolution and Function of MADS-Box Transcription Factors in Plants

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 (Saccharum 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.
