BAD1 — Sorghum bicolor

Summary

SORBI_3007G140700 (BAD1) on sorghum chromosome 7 encodes an aldehyde dehydrogenase family protein with multiple NAD⁺-dependent activities, including betaine-aldehyde, succinate-semialdehyde, and coniferyl-aldehyde dehydrogenase functions. The gene is associated with GABA catabolism, the GABA shunt, and cellular detoxification of aldehydes. It is linked to responses to water, desiccation, salt, and insects, as well as to defense responses involving callose deposition, reactive oxygen species metabolism, and induced systemic resistance. Associations with leaf water potential, photosynthetic rate, grain filling period, root morphology, and disease tolerance have been noted. The protein is predicted to localize to mitochondria, vacuoles, the apoplast, chloroplast stroma, and endoplasmic reticulum. Studies of related genes in other species connect the family to abiotic stress tolerance, osmotic adjustment, and grain quality traits.
