Rice plant architecture significantly influences crop yield and resilience, making it a critical focus in agricultural research. This study aims to elucidate the roles of the SD1 and MOC1 genes in shaping rice plant structure and enhancing yield. The SD1 gene, essential for gibberellin biosynthesis, is analyzed for its contributions to dwarfism, stem strength, and overall yield improvements, including lodging resistance and grain filling. Concurrently, the MOC1 gene, which regulates tillering and branching, is examined for its impact on tillering numbers, root and shoot architecture, and yield optimization. The interplay between SD1 and MOC1 is explored, highlighting their synergistic effects on plant growth, balanced morphology, and combined yield contributions. Breeding strategies employing traditional and modern genetic techniques are discussed, with case studies demonstrating the successful integration of these genes into high-yielding and stress-resilient cultivars. Future research directions, including emerging studies on SD1 and MOC1, potential yield enhancements, and sustainability challenges, are considered. The study concludes by summarizing key findings and discussing their implications for future research and breeding programs.
