Cover Story: We developed a method for the direct measurement of leaf Eh (redox potential) and pH, which revealed spatial, temporal, and genotypic variations in rice. The Eh of the last fully expanded leaf decreased after sunrise and increased with plant age. Leaf Eh was high in the youngest leaf, and its minimum occurred in the last fully expanded leaf. Leaf pH decreased from youngest to oldest leaves. These patterns and dynamics in leaf Eh-pH are in accordance with the patterns and dynamics of disease infections. Leaf Eh-pH is proposed as a novel indicator of plant stress/health. View the paper here.
