DH1 — Oryza sativa Indica Group

Summary

BGIOSGA029110 (symbol DH1, also known as OiDH1) on chromosome 8 of indica rice encodes a protein with aldo-keto reductase (NAD) activity and multiple dehydrogenase activities, including D-xylulose reductase, sorbitol-6-phosphate 2-dehydrogenase, ribitol 2-dehydrogenase, L-idonate 5-dehydrogenase, coniferyl-alcohol dehydrogenase, S-(hydroxymethyl)glutathione dehydrogenase, and cinnamyl-alcohol dehydrogenase. The protein contains SDH-like, ADH-like, and PKS_ER domains, binds zinc, and localizes to the plasmodesma, plastid, and cytosol. DH1 is associated with L-idonate breakdown, sorbitol metabolism, methanal catabolism, the MAPK cascade, and phenylpropanoid and lignin anabolism. It is linked to submergence tolerance and plant height. Related genes in other species are associated with grain lysine content, amylopectin content, protein content, grain yield, drought tolerance and recovery, seedling height, root traits, and lignin content.
