Response of wheat to abiotic and biotic stresses. Hydrogen peroxide, a component of wound response and oxidative-burst defense against pathogens, is detectable after staining with 3,3-diaminobenzidine in crown tissue adjacent to severed roots and in leaf tissue infested with powdery mildew fungus. Although virulent first-instar Hessian fly larvae elicit a gene-for-gene defense, oxidative burst is not involved in either compatible or incompatible interactions. [View Article]
