ALS — Brassica oleracea var. botrytis

Summary

BoALS (BOLND125_C08P034720.1_BOLND125_V1) on cauliflower chromosome 8 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. The gene is associated with branched-chain amino acid biosynthesis, particularly valine anabolism, as well as response to herbicide, hypersensitivity, protein transport, homeostasis, signal transduction, and photosynthetic rate. It has been connected to herbicide tolerance. Studies of related ALS genes in other species link the family to herbicide resistance (including sulfonylurea and imidazolinone tolerance), seed production, plant growth, and traits such as seed weight, plant height, starch content, and heterosis.
