Sorbitol dehydrogenase aids grain-fill and integrates carbohydrate metabolism with redox in the hypoxic maize endosperm

Abstract Extreme low oxygen is typical of microenvironments inside developing grains, thus requiring metabolic adaptations to hypoxia. Potential contributions from sorbitol dehydrogenase (SDH) are tested here for maize (Zea mays) since the reversible reaction (fructose + NADH ↔ s...
