ACT4 — Glycine max

Summary

GmACT4 (GLYMA_11G139800V4) 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 localises to the actin cytoskeleton, Golgi membrane, endosome, chloroplast envelope, plant-type cell wall and plasmodesmata. GmACT4 is associated with numerous agronomic traits including grain yield, seed morphology and protein content, biomass yield, photosynthetic rate, root nodule number, root volume and weight, phosphorus and nitrate uptake, leaf water content and chlorosis, abscisic acid and proline content, and osmotic response sensitivity. It is also linked to actin filament dynamics, root hair growth, pollen tube elongation, cytokinesis, vesicle trafficking, seed and endosperm morphogenesis, disease resistance, and immune responses. Studies of related genes in other species connect the actin family to pollen and root hair development, cell division, pavement cell morphogenesis, plant height, and cold tolerance.
