ACT — Nicotiana attenuata

Summary

A4A49_14085 (ACT7) on coyote tobacco chromosome 5 encodes an actin family protein with profilin, phospholipid, actin, F-actin, protein kinase, and copper binding activities, as well as phosphatase and hydrolase activities, and acts as a structural constituent of the cytoskeleton. It is associated with actin filament-based processes including nucleation, stabilization, depolymerization, and capping, as well as pronuclear migration, karyogamy, cell tip growth, cytoskeleton organization, Golgi-to-plasma membrane transport, and response to nutrient. The gene is linked to numerous traits including seed morphology, vegetative vigor, leaf area, water stress response, nitrogen and potassium sensitivity, shoot growth angle, seed yield, root hair length, nitrate uptake, trichome morphology, brassinosteroid sensitivity, ethylene sensitivity, cell elongation, and wheat powdery mildew disease response. Related genes in other species are linked to leaf senescence, drought resistance, aphid resistance, and hypersensitive response.
