ATPB — Beta vulgaris subsp. vulgaris

Summary

BvATPB (ATPB) on sugar beet chromosome 6 encodes a protein with ATP synthase F1 beta subunit and related domains, and is annotated with proton-transporting ATP synthase activity, rotational mechanism, as well as numerous other molecular functions including protein ser/thr kinase activator activity, histone acetyltransferase activity, and ATP hydrolase activity. The gene is associated with proton motive force-driven ATP synthesis, phosphoglyceride metabolism, inositol phosphate metabolism, tRNA charging, glutathione metabolism, brassinosteroid-mediated signalling, and upregulation of long-day photoperiodism and flowering. It has been linked to traits such as plant stress response, flowering time, plant growth and development, and root morphology. The encoded protein localises to the F1-F0 complex, mitochondrial inner membrane, chloroplast thylakoid membrane, chloroplast envelope, apoplast, nucleolus, and other compartments. Studies of related genes in other species connect the family to cytoplasmic male sterility, protein content, and cold tolerance.
