BADH — Oryza sativa Japonica

Summary

OsBADH (OS02G0730000) on rice chromosome 2 encodes a betaine-aldehyde dehydrogenase, an aldehyde dehydrogenase domain-containing enzyme with acetaldehyde, phenylacetaldehyde, coniferyl-aldehyde, succinate-semialdehyde, and benzaldehyde dehydrogenase activities, and also annotated for Na+ ion binding. The gene is associated with grain fragrance and aroma, submergence tolerance, male reproductive development, tapetum degeneration, programmed cell death, and stress tolerance including salinity, drought, and temperature extremes. It is linked to glycine betaine and GABA metabolism, ethanol metabolism, cellular detoxification of aldehydes, and the GABA shunt. Localisation evidence connects the product to mitochondria, vacuole, apoplast, cell wall, chloroplast stroma, ER, and Golgi. Associations also extend to grain yield, plant height, stem diameter, photosynthetic rate, pollen fertility, and disease tolerance.
