BADH — Oryza sativa Japonica

Summary

OsBADH (Os02g0173900) encodes a member of the aldehyde dehydrogenase superfamily, with betaine-aldehyde dehydrogenase, succinate-semialdehyde dehydrogenase, and multiple other aldehyde dehydrogenase activities. In rice, the gene is associated with grain fragrance and aroma, particularly through the BADH2 variant, and with submergence tolerance, salinity and drought stress tolerance, and male reproductive development including tapetum degeneration and programmed cell death. It has been linked to pollen development, root morphology, and stress tolerance generally. The gene product localises to mitochondria, vacuoles, the apoplast, chloroplast stroma, and the endoplasmic reticulum. Associations also connect OsBADH to grain yield, plant height, stem diameter, photosynthetic rate, protein content, disease tolerance, and salt tolerance. Studies of related genes in other species link the family to osmotic and drought stress tolerance and glutathione homeostasis.
