ACT1 — Zea mays

Summary

ZM00001EB055330 (ACT1) on maize chromosome 1 encodes an actin family protein with ATPase and structural cytoskeletal domains, and is annotated with profilin, actin, F-actin, phospholipid, and protein kinase binding, as well as protein phosphatase and transglycosidase activities. The gene is associated with the actin cytoskeleton, Arp2/3 and SCAR complexes, and processes including actin filament stabilization, barbed-end capping, and actin gel formation. It is linked to numerous agronomic traits such as seed morphology, stearic and oleic acid content, ear diameter, seedling vigor, root system morphology, vegetative vigor, leaf area, water stress response, nitrogen sensitivity, and shoot dry weight. Studies of related genes in other species connect the family to leaf size, drought resistance, osmotic stress tolerance, aphid resistance, root hair development, and cell division.
