ACT4 — Glycine max

Summary

GmACT4 (GLYMA_13G335600V4) encodes an actin family protein with ATP binding, hydrolase activity, transglycosidase activity, actin and profilin binding, and functions as a structural constituent of the cytoskeleton. In soybean, this gene is associated with seed morphology, seed coat color, germination rate, root hair length, root thickness, and cell elongation. It has been linked to drought tolerance, osmotic response sensitivity, photosynthetic rate, and disease tolerance. The encoded protein localizes to the actin cytoskeleton, plasmodesmata, chloroplast envelope, and plant-type cell wall. GmACT4 is associated with actin filament stabilization, barbed-end actin filament capping, actin depolymerization, root hair growth, pollen tube elongation, cytokinesis, and vesicle trafficking. Studies of related genes in other species link the family to root hair development, cell division, pavement cell morphogenesis, and plant height.
