ALS — Oryza sativa Indica Group

Summary

BGIOSGA038349 (OiALS) encodes an acetolactate synthase large subunit, a thiamine pyrophosphate-dependent enzyme that exhibits acetolactate synthase, 2-hydroxyacyl-CoA lyase and pyruvate decarboxylase activities, binds TPP, FAD and magnesium, and localises to the chloroplast stroma as part of the acetolactate synthase complex. In indica rice, OiALS is associated with response to herbicide, fatty acid alpha-oxidation, valine biosynthesis and syngamy. The gene is linked to imidazolinone and general herbicide tolerance, aluminium resistance and aluminium tolerance. Studies of related genes in other species connect the family to herbicide resistance (including sulfonylurea and imidazolinone classes), plant growth and development, tiller number, grain yield, drought tolerance, seed production, and quality traits such as protein content.
