AAC1 (TRAESCS1B02G283900) — triticum aestivum

Summary

TRAESCS1B02G283900 (TaAAC1) on bread wheat chromosome 1B encodes a protein with an actin/actin-like conserved domain and ATPase nucleotide-binding domain. The product exhibits structural constituent of cytoskeleton, actin binding, F-actin binding, profilin binding, phospholipid binding, protein kinase activator activity, protein serine/threonine phosphatase activity, and copper binding molecular functions. It is associated with actin cortical patch organization, barbed-end actin filament capping, wound healing, cell migration, tissue remodeling, telophase, meiosis I, response to K+ ion, regulation of triglyceride catabolic process, and nutrient storage. The protein localizes to the actin cytoskeleton, SCAR complex, Golgi membrane, and Cul4-RING E3 ubiquitin ligase complex. TaAAC1 is linked to numerous agronomic traits including grain volume, grain shape, flour color, seedling vigor, frost damage, canopy temperature, leaf area, spikelet density, root system morphology, adventitious root number, root branching, water stress response, nitrogen sensitivity, and hybrid incompatibility. Studies of related genes in other species connect the family to root hair elongation, salt stress adaptation, germination, and nuclear organization.
