The researchers studied different types of rice plants to see how they respond to drought stress during the flowering stage. They found that drought-insensitive rice plants are better at maintaining their water levels and photosynthesis compared to drought-sensitive plants. Drought-insensitive plants also have higher efficiency in transporting photosynthates. This means that some rice plants are better at coping with drought conditions than others, which could be important for improving crop resilience in the face of climate change.
