AAC1 — Brachypodium distachyon

Summary

BRADI_1G10630V3 (BdAAC1) on chromosome 1 of Brachypodium distachyon encodes an actin-family protein with an ATPase nucleotide-binding domain. The product exhibits actin binding, structural constituent of cytoskeleton, profilin binding, phospholipid binding, protein kinase activator activity, and protein phosphatase activity. It is associated with actin filament-based processes including nucleation, depolymerization, stabilization, and capping, as well as cytoskeleton organization, endomembrane organization, and Golgi-to-plasma membrane transport. BdAAC1 has been linked to numerous agronomic traits including seed morphology, endosperm morphology, seed yield, seed longevity, grain filling, vegetative and seedling vigor, leaf area, root system morphology, shoot growth angle, branching, water stress response, osmotic sensitivity, nitrogen and potassium sensitivity, cadmium and iron concentration, and responses to powdery mildew and aphids. Related genes in other species are linked to root hair elongation, germination, salt stress adaptation, and nuclear organization.
