BADH1 (TRAESCS2B02G346000) — triticum aestivum

Summary

TRAESCS2B02G346000 (symbol TaBADH, also known as BADH1) on wheat chromosome 2B encodes an aldehyde dehydrogenase domain-containing protein with betaine-aldehyde dehydrogenase (NAD⁺) activity, as well as multiple related aldehyde dehydrogenase and glyceraldehyde-3-phosphate dehydrogenase activities. The gene is associated with GABA catabolism, the GABA shunt, cellular detoxification of aldehydes, and responses to anoxia, desiccation, salt, and insects. It has been linked to grain yield, grain texture, grain filling period, photosynthetic rate, osmotic adjustment capacity, disease tolerance, and root morphology traits. The encoded protein localises to mitochondria, vacuoles, the apoplast, chloroplast stroma, and the endoplasmic reticulum. Studies of related genes in other species connect the family to salt, drought, and submergence tolerance, as well as grain fragrance and pollen development.
