AAC1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0457850 (HvAAC1) on barley chromosome 5H encodes a protein containing actin and ATPase domains and is annotated with structural constituent of the cytoskeleton, actin binding, protein kinase activator activity, and protein phosphatase activity. The gene is associated with actin filament-based processes, cytoskeleton organization, and regulation of triglyceride catabolism. It has been linked to numerous agronomically important traits including seed morphology, grain filling period, seed yield, starch grain synthesis, seedling vigor, vegetative vigor, leaf area, root system morphology, water stress response, nitrogen sensitivity, cadmium and iron concentration, and wheat powdery mildew disease response. Associations also include reproductive development, pollen tube growth, drought resistance, osmotic stress tolerance, and aphid resistance. Studies of related genes in other species link the family to ovule development, cell division, root hair development, and abiotic stress response.
