ACT4 — Phaseolus vulgaris

Summary

PHAVU_007G260000, designated ACT4 (also known as PvACT4 or PvACT12) on French bean chromosome 7, encodes a protein with actin/actin-like and ATPase domains, and is annotated with profilin binding, F-actin binding, structural constituent of cytoskeleton, actin binding, hydrolase activity, transglycosidase activity, ATP binding, and protein binding. The gene is associated with actin cytoskeleton organization, actin filament stabilization, polymerization, depolymerization, nucleation, and capping, as well as cytoplasmic streaming, cell tip growth, cell adhesion, and response to water. It is linked to seed morphology, endosperm morphology, root hair length, photosynthetic rate, cell elongation, root development, hypocotyl morphology, root thickness, disease tolerance, and osmotic response sensitivity. Localization evidence connects the product to the actin cytoskeleton, Golgi membrane, endosome, chloroplast envelope, plant-type cell wall, and plasmodesmata. Studies of related genes in other species link the family to pollen development, root hair development, cell division, pavement cell morphogenesis, and xyloglucan biosynthesis.
