BAD1 — Sorghum bicolor

Summary

SORBI_3004G058600 (BAD1) on sorghum chromosome 4 encodes a succinate-semialdehyde dehydrogenase, a member of the aldehyde dehydrogenase superfamily, with glyceraldehyde-3-phosphate dehydrogenase (NAD) activity. This gene is associated with GABA catabolism, the GABA shunt, cellular detoxification of aldehydes, and responses to anoxia, water, desiccation, and insects. It is linked to leaf water potential, grain filling period, photosynthetic rate, disease tolerance, root morphology, and plant growth and development traits. Associations also include salt, drought, osmotic, heat, and combined stress tolerance, as well as aldehyde detoxification, redox homeostasis, photosynthetic capacity and efficiency, and herbicide tolerance. The gene product localizes to the mitochondrial lumen, vacuole, apoplast, cell wall, chloroplast stroma, ER, and Golgi. Studies of related genes in other species connect the family to grain fragrance, aroma, glycine betaine synthesis, submergence tolerance, male sterility, and grain size.
