DH1 — Oryza sativa Indica Group

Summary

BGIOSGA029109 (symbol DH1, also known as OiDH1 or ADH1) on chromosome 8 of Indica rice encodes a protein with an SDH-like domain and ADH-like regions, possessing multiple oxidoreductase activities including D-xylulose reductase, sorbitol-6-phosphate 2-dehydrogenase, and ribitol 2-dehydrogenase (NAD+) activities. The gene is associated with L-idonate breakdown, sorbitol metabolism, methanal catabolism, the MAPK cascade, and phenylpropanoid anabolism. Its product localizes to the plasmodesma, plastid, cytosol, and cytoplasm. DH1 is associated with submergence tolerance and plant height. Studies of related genes in other species link the family to grain lysine content, drought recovery, amylopectin content, seedling height, root traits, lignin content, protein content, grain yield, and drought tolerance.
