ALS — Oryza sativa Japonica

Summary

Os02g0510200 (ALS) in rice encodes an acetolactate synthase, a thiamine pyrophosphate-dependent enzyme. The gene is associated with response to herbicide, detoxification, and branched-chain amino acid anabolism, including valine biosynthesis. It has been connected to plant height and grain yield, as well as aluminium tolerance and resistance. The ALS protein localises to the chloroplast stroma and the acetolactate synthase complex. Studies of related genes in other species link the family to herbicide resistance and sensitivity, including imidazolinone and sulfonylurea tolerance, as well as drought tolerance, tillering, and seed production.
