Abstract
Rice (Oryza sativa), a crucial global staple, grapples with environmental stress and resource constraints, necessitating sustainable farming. This review explores the transformative role of transcription factors (TFs) in revolutionizing rice agriculture and their potential impact on global food security. It underscores TFs’ pivotal role in gene expression, particularly in responding to environmental stimuli, presenting a promising avenue for enhancing rice resilience. Delving into key TF families in rice, it highlights their multifaceted roles in abiotic stress responses, defense mechanisms, yield improvement, nutrient uptake, seed development, photosynthesis, and flowering regulation. Specific TFs, including DREB (Dehydration-Responsive Element-Binding), WRKY, NAC, MYB (Myeloblastosis), AP2/ERF (APETALA2/Ethylene Responsive Factor), and bHLH (basic Helix–Loop–Helix), are examined for their contributions to stress resilience, defense mechanisms, and yield enhancement. Concrete examples from cutting-edge research illustrate the tangible benefits of harnessing these molecular regulators. However, manipulating TFs presents challenges, necessitating innovative approaches such as predictive models, collaborative field testing, and transparent communication to navigate intricate regulatory networks and regulatory hurdles. Ultimately, a promising future emerges where manipulating rice TFs leads to the development of resilient, high-yielding, and nutritious varieties. Embracing research advancements and addressing existing challenges is imperative to unlock the full potential of these concealed regulators, ensuring sustainable food security for a growing global population.
