ALS — Brassica napus

Summary

BnALS (DARMORV10_A05P03300.1) on chromosome A05 of oilseed rape encodes an acetolactate synthase (ALS) enzyme, also known as acetohydroxyacid synthase (AHAS), which possesses acetolactate synthase, pyruvate decarboxylase, and 2-hydroxyacyl-CoA lyase activities, binds thiamine pyrophosphate, FAD, and magnesium, and localises to the chloroplast stroma as part of the acetolactate synthase complex. The gene is associated with branched-chain amino acid biosynthesis, valine and glucosinolate anabolism, response to herbicide and nutrient levels, autophagic cell death, anther development, pollen exine formation, and detoxification. It has been linked to traits including seed weight, plant height, protein, starch, oleic acid, and carbohydrate content, photosynthetic rate, and heterosis. Related genes in other species are linked to herbicide resistance and sensitivity, imidazolinone and sulfonylurea tolerance, and plant growth and seed production.
