ATPB — Asparagus officinalis
Summary
AoATPB (ATPB, ATPE) on asparagus chromosome 6 encodes the beta subunit of the F1 ATP synthase complex (EC 7.1.2.2), a core component of the proton-transporting ATP synthase. The gene is associated with proton motive force-driven ATP synthesis, brassinosteroid-mediated signalling, and regulation of metabolism. It has been linked to flowering time, plant growth and development, root morphology, and stress response traits. Localisation evidence places the product in the mitochondrial inner membrane, chloroplast thylakoid membrane, and other compartments including the apoplast, nucleolus, and Golgi. Studies of related genes in other species connect the ATPB family to cytoplasmic male sterility, protein content, and cold tolerance.
