GK — Zea mays

Summary

ZmGK (ZM00001EB419400) on maize chromosome 10 encodes an acetyl-CoA carboxylase (EC 6.4.1.2) with biotin carboxylase activity, also annotated as a protein folding chaperone. The gene is associated with malonyl-CoA anabolism, fatty acid oxidation, regulation of lipogenesis, and plastid gene expression, and localizes to mitochondria, chloroplast stroma and thylakoids, cytosol, and nucleus. In maize, ZmGK has been linked to grain yield, seed weight, plant height, leaf angle, anthesis time, heterosis, herbicide sensitivity, and salt tolerance. Related genes in other species are associated with embryo development, cuticular wax deposition, very long chain fatty acid elongation, and stress responses including cold and drought tolerance.
