BAD1 — Sorghum bicolor

Summary

SORBI_3002G426100 (BAD1) on sorghum chromosome 2 encodes an aldehyde dehydrogenase family protein with oxidoreductase activity acting on aldehyde or oxo groups of donors with NAD or NADP as acceptor, including betaine-aldehyde dehydrogenase, succinate-semialdehyde dehydrogenase, and coniferyl-aldehyde dehydrogenase activities, and binds NAD, Na⁺, and K⁺ ions. The gene is associated with GABA catabolism and the GABA shunt, cellular detoxification of aldehydes, response to anoxia, desiccation, water, and insects, as well as defense response by callose deposition, induced systemic resistance, and reactive oxygen species metabolism. It is linked to leaf water potential, photosynthetic rate, grain filling period, root morphology, plant growth and development, disease tolerance, and stress response traits. The product localizes to mitochondria, vacuoles, apoplast, cell wall, chloroplast stroma, endoplasmic reticulum, and Golgi. Related genes in other species connect the family to abiotic stress tolerance, osmotic stress response, drought and heat stress tolerance, photosynthetic efficiency, and redox homeostasis, as well as to grain size, male sterility, and fungal blast resistance.
