ACT4 — Phaseolus vulgaris

Summary

PvACT4 (PHAVU_001G142500) on chromosome 1 of French bean encodes an actin protein with ATP binding, hydrolase activity, and structural constituent of the cytoskeleton functions, along with profilin and F-actin binding. It is associated with actin cytoskeleton organization, polymerization, depolymerization, nucleation, filament stabilization, and capping, as well as cytoplasmic streaming, cell tip growth, cell adhesion, and response to water. The gene is linked to seed morphology, endosperm morphology, root hair length, cell elongation, photosynthetic rate, osmotic response sensitivity, organ identity, root development, hypocotyl morphology, root thickness, disease tolerance, and salt tolerance. It localizes to the actin cytoskeleton, Golgi membrane, endosome, chloroplast envelope, plant-type cell wall, and plasmodesmata. Related genes in other species connect it to pollen development, root hair development, cell division, pavement cell morphogenesis, and cold tolerance.
