ACT7 — Zea mays

Summary

ZM00001EB366720 (ACT7) on maize chromosome 8 encodes an actin protein that is a structural constituent of the cytoskeleton, with ATP binding and hydrolase activity, and localizes to the actin cytoskeleton and nucleus. The gene is associated with diverse biological processes including lipid raft organization, chemosensory perception, aflatoxin breakdown, glycine betaine anabolism, and ethene metabolism. It has been linked to numerous agronomically relevant traits such as grain lysine content, carotene and zeaxanthin content, flag leaf area, forage yield, ear weight, germination ratio, chilling stress response, aluminum tolerance, leaf water potential, turgor pressure, and plant height. Additional associations include fruit and flower color, seed color, leaf sheath color, brittle culm, rootless phenotype, and liguleless. Studies of related genes in other species place the family within the ATPase superfamily (EC 3.6.4.-).
