ALS — Glycine max

Summary

GLYMA_15G072500V4, also known as GmALS, encodes the large subunit of acetolactate synthase (ALS), an enzyme that catalyses the first committed step in the biosynthesis of branched-chain amino acids such as valine. The protein contains thiamine pyrophosphate (TPP)-binding and FAD-binding domains, and its activity is localised to the chloroplast stroma as part of the acetolactate synthase complex. In soybean, this gene is associated with response to herbicide, salt stress, nitrogen fixation, nodulation, photorespiration, and secondary and lipid metabolism. It has also been linked to agronomic traits including seed weight, plant height, and nitrogen content. Studies of related genes in other species connect the ALS family to herbicide resistance and sensitivity, particularly to sulfonylurea and imidazolinone herbicides, as well as to plant growth and seed production.
