DH1 — Zea mays

Summary

ZM00001EB037520 (ZmDH1, also known as CAD3, ADH1, CAD1 or DH1) on maize chromosome 1 encodes a protein with aldo-keto reductase and cinnamyl-alcohol dehydrogenase activities, belonging to the ADH-like and SDH-like families. The gene is associated with multiple oxidoreductase functions including D-xylulose reductase, sorbitol-6-phosphate 2-dehydrogenase, and coniferyl-alcohol dehydrogenase activities. It has been linked to grain lysine content, amylopectin content, lignin content, protein content, and grain yield, as well as seedling height, shoot and root dry weight, root length and number, and submergence tolerance. The product localises to the cytosol, plastid, and plasmodesmata, and is associated with processes including sorbitol metabolism, cell wall polysaccharide anabolism, anaerobic respiration, and DNA modification. Studies of related genes in other species connect the family to drought tolerance and recovery.
