AI Technical Summary
Technical Problem
Rice growth is highly dependent on water resources, and drought leads to severe yield losses. Current technologies lack effective methods to improve the drought resistance of rice.
Method used
By editing the rice aspartic protease gene OsAP25 using CRISPR-Cas9 technology, loss-of-function mutants CRS2, CRS6, and CRS10 were created, enhancing the expression of drought-related genes and improving rice's resistance to drought stress.
Benefits of technology
It significantly improves the resistance of rice to drought stress, enhances the expression of related genes, and improves the physiological drought tolerance and yield of rice.
