ALS — Brassica napus

Summary

BnALS (DARMORV10_A01P25340.1) on chromosome A01 of oilseed rape (Brassica napus) encodes an acetolactate synthase (ALS) large subunit, a thiamine pyrophosphate-dependent enzyme with acetolactate synthase, pyruvate decarboxylase and 2-hydroxyacyl-CoA lyase activities. This gene is associated with branched-chain amino acid biosynthesis, valine biosynthesis, and response to herbicide, as well as autophagic cell death, autophagy regulation, pollen exine formation, anther development, glucosinolate biosynthesis, phenylpropanoid biosynthesis, fatty acid alpha-oxidation, detoxification, cell wall modification, ribosome biogenesis, and secondary metabolism. It localises to the chloroplast stroma and acetolactate synthase complex. Associations with agronomic traits include plant height, seed weight, starch content, protein content, oleic acid content, carbohydrate content, photosynthetic rate, and heterosis. A specific G121A variant is linked to herbicide tolerance. Related genes in other species are associated with sulfonylurea and imidazolinone herbicide resistance, seed production, and plant growth.
