F5 and glycogen storage disease VI: This study further demonstrated that thph2 functions as an elicitor capable of directly interacting with maize leaves to induce ROS burst, thereby enhancing host resistance in both N. benthamiana against S. sclerotiorum and maize (Zea mays) against southern corn leaf blight (SCLB), Collectively, our data suggest that Thph2 functions as a conserved elicitor of PTI, enabling broad-spectrum disease resistance in phylogenetically distant plant species.
