ATPB — Beta vulgaris subsp. vulgaris

Summary

BvATPB (ATPB) on sugar beet chromosome Bvchr3_un.sca009 encodes a protein belonging to the ATPase alpha/beta chains family, with proton-transporting ATP synthase activity, rotational mechanism, and additional annotated functions including protein serine/threonine kinase activator activity, histone acetyltransferase activity, and various ion-binding capacities. The gene is associated with chloroplast thylakoid membrane, F1-F0 complex, and other cellular locations. It is associated with biological processes including proton motive force-driven mitochondrial ATP synthesis, brassinosteroid-mediated signalling, upregulation of long-day photoperiodism and flowering, and phosphoglyceride metabolism. Associations with plant stress response, flowering time, root morphology, and plant growth and development traits have been noted. Studies of related genes in other species connect the family to cold tolerance, cytoplasmic male sterility, and responses to low temperature and oxidative stress.
