ACT — Nicotiana attenuata

Summary

A4A49_64093 (ACT, AC101) in coyote tobacco (Nicotiana attenuata) encodes a protein with an actin conserved site and ATPase domain, and is annotated with actin-binding, profilin-binding, phospholipid-binding, and protein serine/threonine phosphatase activity, as well as structural constituent of the cytoskeleton. This gene is associated with biological processes including actin filament stabilization, nucleation, and depolymerization, as well as cell tip growth, cytoskeleton organization, and pronuclear migration. It is linked to traits such as seed morphology and yield, leaf area, vegetative vigor, root hair length, shoot branching, and responses to water stress, osmotic stress, aphids, and powdery mildew. The encoded protein localizes to the actin cytoskeleton, Golgi membrane, and endosomes. Related genes in other species are linked to drought resistance, hypersensitive response, and leaf senescence.
