ADH — Zea mays

Summary

ZmADH (ZM00001EB185610) on maize chromosome 4 encodes an alcohol dehydrogenase with S-nitrosoglutathione reductase, S-(hydroxymethyl)glutathione dehydrogenase, and aldo-keto reductase activities, binding zinc, calcium, and NAD(P). The gene is associated with anaerobic respiration, ethanol and formaldehyde metabolism, hypoxic stress response, and carbohydrate storage, and its product localises to the cytosol, plastid, mitochondria, nucleus, and plasma membrane. ZmADH has been linked to seedling height, root and shoot biomass, photosynthetic rate, leaf senescence, lignin and protein content, and tolerance to drought, low temperature, submergence, waterlogging, hypoxia, salt, and chilling. It is also connected to herbicide sensitivity, lateral root number, fertility, stomatal closure, and aldehyde detoxification. Studies of related genes in other species link the family to freezing tolerance, nitric oxide signalling, and systemic acquired resistance.
