ACT — Solanum tuberosum

Summary

PGSC0003DMG400008912 (ACT/AC71) on potato chromosome 9 encodes Actin-71, a structural constituent of the cytoskeleton with actin, profilin, phospholipid, F-actin and protein kinase binding activities, as well as protein phosphatase and hydrolase activities. It is associated with actin filament organization, stabilization, nucleation and depolymerization, cytoskeleton organization, cell tip growth, morphogenesis, hormone transport, and responses to nutrients and potassium. The gene is linked to numerous agronomic traits including seed morphology and yield, vegetative vigor, leaf area, shoot growth angle, root hair length, root mass density, water stress response, nitrogen and potassium sensitivity, brassinosteroid and ethylene sensitivity, cell cycle and elongation traits, and wheat powdery mildew disease response. Localization evidence connects it to the actin cytoskeleton, Golgi, endosomes, chloroplast envelope, and the Arp2/3 protein complex.
