ALS — Brassica napus

Summary

BnALS (DARMORV10_C01P32280.1) on chromosome C01 of oilseed rape encodes an acetolactate synthase large subunit, a thiamine pyrophosphate-dependent enzyme. The gene is associated with acetolactate synthase, pyruvate decarboxylase and 2-hydroxyacyl-CoA lyase activities, and localises to the chloroplast stroma and acetolactate synthase complex. It is associated with valine and branched-chain amino acid biosynthesis, autophagic cell death, autophagy regulation, herbicide response and detoxification, as well as anther development, microsporogenesis, glucosinolate and phenylpropanoid biosynthesis, and cell wall modification. Associations with agronomic traits include seed weight, plant height, protein, starch, oleic acid and carbohydrate content, heterosis, and photosynthetic rate. A specific G121A substitution is linked to herbicide tolerance. Related genes in other species are associated with sulfonylurea and imidazolinone herbicide resistance.
