ALS — Brassica oleracea

Summary

BoALS (BOLC102_C08P033880.1) on cabbage chromosome 8 encodes an acetolactate synthase (ALS) enzyme that possesses pyruvate decarboxylase and acetolactate synthase activities, binds TPP, FAD, magnesium and other proteins, and localises to the chloroplast stroma as part of the acetolactate synthase complex. The gene is associated with branched-chain amino acid biosynthesis, including valine anabolism, and with responses to nutrients and herbicides. It has been linked to seed development, seed weight, plant height, photosynthetic rate and oleic acid content. A specific G121A variant is linked to herbicide tolerance. Studies of related genes in other species link the family to resistance to imidazolinone and sulfonylurea herbicides, as well as to carbohydrate, starch and protein content, heterosis and plant growth.
