ALS — Phaseolus vulgaris

Summary

PHAVU_009G166100, designated PvALS, encodes a protein with acetolactate synthase activity, 2-hydroxyacyl-CoA lyase activity, and pyruvate decarboxylase activity, and binds thiamine pyrophosphate, FAD, and magnesium. It localises to the chloroplast stroma as part of the acetolactate synthase complex. In French bean, this gene is associated with branched-chain amino acid biosynthesis, valine anabolism, fatty acid alpha-oxidation, and response to herbicide. A specific G121A variant is linked to herbicide tolerance. Studies of related genes in other species connect the family to imidazolinone and sulfonylurea herbicide resistance, as well as to traits including seed weight, plant height, nitrogen content, amino acid content, salt response, and overall plant growth and development.
