AAC1 — Brassica oleracea var. botrytis

Summary

BoAAC1 (AAC1, ACT1, BoACT3) on cauliflower chromosome 6 encodes an actin family protein with an actin/actin-like conserved site and ATPase nucleotide-binding domain, annotated with structural constituent of cytoskeleton, F-actin binding, phospholipid binding, hydrolase, calcium ion binding, protein serine/threonine kinase activity, ATP binding, and protein binding functions. The gene is associated with actin depolymerization, cytoskeleton organization, potassium ion import, response to nutrient, developmental growth, regeneration, red/far-red light response, translation initiation, pollen germination and development, stomatal movement, innate immune response-activating signaling pathway, defence response to bacteria, and responses to heat, cold, salinity, and thirst. It localizes to the actin cytoskeleton, plasma membrane, cytosol, ER, mitochondria, plastid, plasmodesma, plant-type cell wall, and Cul4-RING E3 ubiquitin ligase complex. Associations include leaf area, flowering time, root mass density, seedling hypocotyl length, cell elongation, stomatal complex closure time, water stress, nitrogen/potassium/magnesium sensitivity, iron concentration, aphid and powdery mildew response, disease tolerance, and vegetative-to-reproductive phase transition. Related genes in other species are linked to disease resistance, hypocotyl morphology, root hair development, abiotic stress, and ion transport.
