Changes in Wheat Metabolism Caused by Powdery Mildew

Abstract

The pathogenesis of Erysiphe graminis tritici infection of wheat was correlated with an increase in fermentation and a larger increase in respiration of the host tissue, these changes occurring in the green cells of the mesophyll not in contact with or invaded by the fungus hyphae. Preliminary measurements indicated that the destruction of functional chlorophyll is subsequent to these other metabolic changes.
