This invention discloses the application of the TOE1 protein and its encoding gene in improving the tolerance of tomatoes to strong light stress or in breeding for strong light tolerance, belonging to the field of biotechnology. This invention is the first to discover that the TOE1 protein and its encoding gene play a crucial role in regulating the strong light adaptation of tomatoes. By inactivating the TOE1 protein or knocking out its encoding gene, the anthocyanin accumulation response in tomatoes under strong light stress can be reduced, thus improving the tomato's tolerance to strong light stress. Using genome editing technologies such as CRISPR / Cas9, targeted knockout of the TOE1 protein was used to create TOE1 mutant materials. These materials can alleviate the growth burden that may be caused by the severe photosensitivity response induced by excessive light in summer or in high-light areas of greenhouse agriculture, helping plants maintain more stable photosynthetic growth under strong light conditions, and providing core germplasm resources for breeding new tomato varieties adapted to high-light environments.
