Rice, as a staple crop, plays a crucial role in global food security; however, flood stress poses significant challenges to its productivity. This study conducts a comprehensive meta-analysis of flood tolerance genes in rice, aiming to understand their genetic contributions and evaluate their impact on key agronomic traits. Utilizing rigorous criteria, statistical methodologies, and bioinformatics tools, the analysis synthesizes data from diverse studies to elucidate the distribution, frequency, and functional roles of genes associated with flood tolerance, such as SUB1A. A detailed case study on the SUB1A gene highlights its discovery, molecular mechanisms, and practical applications in enhancing submergence tolerance. The findings underscore the agronomic implications of flood tolerance genes, including yield stability and economic benefits in flood-prone regions. Challenges such as gene expression variability and limited phenotypic data are addressed, and future directions emphasize genome editing, multi-omics approaches, and integrated breeding strategies. This study provides critical insights to guide the development of resilient rice varieties, contributing to sustainable agriculture and food security.
