AC97 — Pisum sativum

Summary

PSAT6G129080 (symbol AC97, also known as PsACT4, ACT12, PsACT12, ACTIN, PsACTIN, ACT4) on garden pea chromosome 6LG2 encodes an actin protein, a structural constituent of the cytoskeleton with ATP binding, hydrolase, and transglycosidase activities, and is annotated to profilin and F-actin binding. This gene is associated with actin polymerization and depolymerization, actin filament stabilization and capping, cytoskeleton organization, cell tip growth, nuclear movement, and microtubule assembly. It is linked to seed and endosperm morphology traits, root hair length and thickness, photosynthetic rate, osmotic response sensitivity, cell cycle and elongation traits, 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. Studies of related genes in other species associate the family with pollen development, root hair development, cell division, pavement cell morphogenesis, and xyloglucan biosynthesis.
