BADH — Oryza sativa Japonica

Summary

Os08g0424500, designated BADH in rice (Oryza sativa Japonica) on chromosome 8, encodes an aldehyde dehydrogenase domain-containing protein with betaine-aldehyde dehydrogenase (NAD+) activity and multiple related aldehyde dehydrogenase activities. This gene is associated with grain fragrance and aroma, particularly through the BADH2 allele, and has been linked to submergence tolerance, salt and drought stress responses, and male reproductive development including tapetum degeneration and programmed cell death. It is associated with traits such as grain quality, amylose content, grain length, panicle weight, spikelet fertility, plant height, root morphology, cold tolerance, and disease tolerance. The encoded protein localises to mitochondria, vacuoles, chloroplast stroma, and the endoplasmic reticulum, and is associated with glycine betaine biosynthesis, GABA catabolism, ethanol metabolism, and cellular detoxification of aldehydes.
