Osr40c1 protein interacts with Magnaporthe oryzae Sho1 protein to enhance leaf blast resistance in rice, with the C-terminal domain playing a key role.
- Why it matters: Understanding how rice defends against leaf blast disease is crucial for developing resistant crops, as current knowledge of biotic stress responses remains limited.
- What they did: The study analyzed Osr40c1 gene expression during infection, predicted its interaction with M. oryzae Sho1 protein through in silico methods, and tested resistance in plants overexpressing specific Osr40c1 domains.
- The result: Overexpression of the C-terminal domain containing ARG-201 improved disease resistance, revealing a novel mechanism by which Osr40c1 regulates leaf blast defense in rice.
