AC101 — Lactuca sativa

Summary

AC101 (LSAT_V11C800436410) on lettuce chromosome 8 encodes a protein with actin-binding, profilin-binding, phospholipid-binding, and protein serine/threonine phosphatase activity, and it is a structural constituent of the cytoskeleton. The gene is associated with actin filament organization, stabilization, and depolymerization, as well as cell tip growth, cell morphogenesis, developmental growth, and potassium ion import. It is linked to numerous traits including seed yield, leaf area, vegetative vigor, root hair length, shoot branching, carotenoid content, nitrogen and potassium sensitivity, water stress response, and powdery mildew and aphid response. The encoded protein localizes to the actin cytoskeleton, Arp2/3 complex, Golgi membrane, and endosome. Studies of related genes in other species link the family to root hair development, cell expansion, and stress responses.
