BAD1 — Oryza sativa Indica Group

Summary

BGIOSGA028697 (BAD1/BADH2) on chromosome 8 of Indica rice encodes an aldehyde dehydrogenase family protein with betaine-aldehyde dehydrogenase, succinate-semialdehyde dehydrogenase and glyceraldehyde-3-phosphate dehydrogenase activities. This gene is associated with grain fragrance and aroma, and is linked to grain quality traits, grain size, amylose content, panicle weight and length, leaf length, root length, germination rate, photosynthetic rate, and protein content. It is associated with responses to abiotic stresses including salt, drought, submergence, heat, and osmotic stress, as well as to fungal blast resistance, male sterility, seed development, and programmed cell death. The gene is associated with GABA catabolism, the GABA shunt, proline metabolism, cellular detoxification of aldehydes, and reactive oxygen species metabolism. Studies of related genes in other species link the family to redox homeostasis, photosynthetic capacity, and combined stress tolerance.
