ALS — Brassica napus

Summary

BnALS (DARMORV10_C08P23600.1) on chromosome C08 of oilseed rape encodes an acetolactate synthase (ALS) enzyme, also known as acetohydroxyacid synthase (AHAS), which possesses acetolactate synthase and pyruvate decarboxylase activities, binds thiamine pyrophosphate, FAD and magnesium, and localises to the chloroplast stroma as part of the acetolactate synthase complex. This gene is associated with branched-chain amino acid biosynthesis, valine biosynthesis, and responses to herbicide and nutrient levels. It is linked to autophagic cell death, autophagy regulation, detoxification, glucosinolate and phenylpropanoid biosynthesis, anther development, microsporogenesis, cell wall modification, and lipid metabolism. Associations with agronomic traits include seed weight, plant height, starch and protein content, oleic acid content, photosynthetic rate, heterosis, and herbicide tolerance. Studies of related genes in other species connect the family to herbicide resistance and sensitivity, imidazolinone and sulfonylurea tolerance, and plant growth and seed production.
