G2 — Zea mays

Summary

ZmG2 (ZM00001EB162970) on maize chromosome 3 encodes a protein with multiple enzyme activities including trihydroxybenzophenone synthase, tetrahydroxybenzophenone synthase, biphenyl synthase, acetoacetyl-CoA reductase, trans-2-enoyl-CoA reductase (NADPH), ketoreductase, 3-hydroxyacyl-CoA dehydratase, naringenin-chalcone synthase, and acyltransferase activities, and belongs to the FAE1-type polyketide synthase family. The gene is associated with fatty acid elongation, polyketide biosynthesis, chitin anabolism, pollen adhesion and pollen-stigma interaction, seed growth, pigment accumulation, and glutamate metabolism. It localizes to the fatty acid elongase complex, endoplasmic reticulum membrane, cell wall, chloroplast membranes, mitochondria, and cytosol. ZmG2 is associated with traits including flowering time, plant male sterility, cold tolerance, high temperature stress response, stomatal resistance, leaf angle, rooting depth, root length and thickness, seed coat and pericarp color, anthocyanin content, starch concentration, and grain weight.
