CAD — Oryza sativa Japonica

Summary

Os02g0187800 (CAD, also known as GH2) encodes a cinnamyl-alcohol dehydrogenase (EC 1.1.1.195) with aryl-alcohol dehydrogenase and coniferyl-alcohol dehydrogenase activities, binding zinc and other proteins. The gene is associated with lignin and cellulose biosynthesis, xylem development, abscission, green leaf volatile production, and detoxification. It has been linked to traits including grain weight, yield, shattering, panicle weight, culm strength and diameter, plant height, root weight and length, shoot dry weight, cellulose, lignin and sugar content, photosynthetic rate, and reproductive period. Associations also include disease resistance, bacterial resistance, salicylic acid accumulation, basal thermotolerance, arsenic tolerance and translocation, C6-alcohol production, herbivore predator attraction, tillering, branching, strigolactone and cytokinin responses, ethanol yield, and flowering date. The protein localises to the apoplast, cytosol, cytoplasm and plasmalemma. Studies of related genes in other species link the family to lignin composition, plant defense, ovule development and flowering time.
