ACT4 — Phaseolus vulgaris

Summary

PvACT4 (ACT4) on chromosome MU967757.1 encodes an actin protein, a structural constituent of the cytoskeleton that binds ATP, F-actin, profilin and other proteins, and possesses hydrolase and transglycosidase activities. It is associated with actin cytoskeleton organization, including polymerization, depolymerization, nucleation, filament stabilization and capping, as well as cytoplasmic streaming, cell tip growth, cell adhesion, dedifferentiation, and response to water. The gene has been linked to seed and endosperm morphology, root hair length and thickness, cell elongation, photosynthetic rate, osmotic response sensitivity, organ identity, disease tolerance, and salt tolerance. Localization evidence connects the product to the actin cytoskeleton, Golgi membrane, endosome, chloroplast envelope, plant-type cell wall and plasmodesmata. Related genes in other species link the family to pollen development, root hair development, cell division, pavement cell morphogenesis, xyloglucan biosynthesis, and cold tolerance.
