ACT4 — Glycine max

Summary

GmACT4 (GLYMA_12G063400V4) on soybean chromosome 12 encodes an actin protein with ATP binding, hydrolase, and transglycosidase activities, and it is a structural constituent of the cytoskeleton. It binds profilin, F-actin, and actin, and localizes to the actin cytoskeleton, Golgi membrane, chloroplast envelope, and plasmodesmata. The gene is associated with seed morphology, seed coat color, endosperm morphology, germination rate, root hair length and thickness, hypocotyl morphology, cell elongation, photosynthetic rate, osmotic response sensitivity, drought tolerance, and disease tolerance. It is also linked to actin filament bundle formation, stability, and polymerization, pollen tube elongation and growth, root development, cytokinesis, vesicle trafficking, and immune response. Related genes in other species are linked to pollen development, root hair development, cell division, and pavement cell morphogenesis.
