Rice (Oryza sativa) is one of the most important food crops in the world, and its genome evolution has a significant impact on yield and food safety. This study aims to explore the genome evolution of wild rice and cultivated rice, and compare their genetic diversity, genome structure, functional genes, and evolutionary driving factors. We conducted in-depth research on the origin and evolution of rice, including the origin of wild rice and the domestication process of cultivated rice, and identified key genes that affect rice domestication. By comparing the genome structure, the differences in genome size, structure, and gene expression between wild and cultivated rice were revealed. This study also analyzed genetic diversity and evolutionary pressure, gained a deeper understanding of the genetic differences and environmental adaptability between the two. In exploring the ecological and agricultural significance of rice genome evolution, it elucidated its important impact on ecosystems and agricultural production, as well as future research directions and challenges. This study provides important insights into the evolution of the rice genome and theoretical basis for further improving rice cultivation and food production.
