ACTIN — Cicer arietinum

Summary

ACT4, also known as ACTIN, on chickpea chromosome 3, encodes a structural constituent of the cytoskeleton, an actin-binding protein with profilin-binding, ATP-binding, and hydrolase activities. It is associated with cytoskeleton organization, actin nucleation, depolymerization, and filament stabilization, as well as cell tip growth, cell cycle, cell death, endosperm development, and seed morphogenesis. The gene is linked to numerous traits including seed morphology, germination rate, root development, cell elongation, biomass yield, photosynthetic rate, osmotic response sensitivity, stomatal closure, flowering time, and aphid response. It localizes to the actin cytoskeleton, plant-type cell wall, chloroplast envelope, plasmodesma, and Golgi. Related genes in other species are linked to root hair growth, osmotic stress response, and actin filament dynamics.
