AC97 — Medicago truncatula

Summary

MTR_7G093260 (symbol AC97, also known as MtACT4) encodes an actin family protein with ATPase activity, actin and profilin binding, and a structural constituent of the cytoskeleton. In barrel medic, this gene is associated with actin cytoskeleton organization, including actin nucleation, polymerization, depolymerization, filament stabilization and capping, as well as cell tip growth, exocytosis, and membrane and cytoplasm organization. It is linked to appressorium formation, fucose and xyloglucan anabolism, and methionine metabolism. Localization evidence connects the product to the actin cytoskeleton, Golgi, endosome, chloroplast envelope, plant-type cell wall, and plasmodesmata. The gene has been associated with seed and endosperm morphology, root hair length and thickness, photosynthetic rate, osmotic response sensitivity, disease tolerance, and cell cycle and elongation traits. Related genes in other species link the family to pollen and root hair development, cell division, pavement cell morphogenesis, and xyloglucan biosynthesis.
