OsRFS protein and application thereof

The invention belongs to the technical field of biology, and discloses an OsRFS protein and application thereof. The invention discloses the application of the OsRFS protein in regulating the abiotic stress resistance of the plant, regulating the plant height of the plant and regulating the tiller number of the plant for the first time, the plant height of the plant can be reduced by reducing the expression quantity of the OsRFS protein and/or the activity of the OsRFS protein, and the tiller number of the plant is increased; the abiotic stress resistance can be improved and the plant height can be reduced by improving the expression quantity and/or activity of the OsRFS protein, so that related plant varieties can be cultivated. 本发明属于生物技术领域，公开了OsRFS蛋白及其应用。本发明首次公开了OsRFS蛋白在调控植物的非生物胁迫抗性、调控植物的株高、调控植物的分蘖数中的应用，降低OsRFS蛋白表达量和/或其活性可以降低植物的株高、提高植物的分蘖数，提高OsRFS蛋白表达量和/或其活性可以提高非生物胁迫抗性、降低植物的株高，从而培育相关植物品种。
