BADH — Oryza sativa Japonica

Summary

OS09G0440300 (BADH, ALDH7) encodes a betaine-aldehyde dehydrogenase family member with multiple aldehyde dehydrogenase activities, including succinate-semialdehyde and coniferyl-aldehyde dehydrogenase activity, and is associated with grain fragrance, aroma, and seed development in rice. The gene is linked to abiotic stress tolerance, particularly salinity, drought, and submergence tolerance, as well as male reproductive development, tapetum degeneration, and programmed cell death. It is also associated with grain yield, plant height, root morphology, and photosynthetic rate. The encoded protein localises to mitochondria, vacuoles, chloroplast stroma, and the ER, and is associated with glycine betaine biosynthesis, GABA catabolism, and cellular detoxification of aldehydes. Studies of related genes in other species link the family to osmotic and heat stress tolerance and aldehyde detoxification.
