ATPB — Beta vulgaris subsp. vulgaris

Summary

BvATPB (ATPB) on sugar beet chromosome Bvchr7_un.sca014 encodes a protein with ATPase alpha/beta chains and P-loop NTPase domains, and is annotated with proton-transporting ATP synthase activity, protein serine/threonine kinase activity, histone acetyltransferase activity, and several other molecular functions. The gene is associated with proton motive force-driven mitochondrial ATP synthesis, phosphoglyceride and inositol phosphate metabolism, brassinosteroid-mediated signalling, and upregulation of long-day photoperiodism and flowering. It is linked to flowering time, plant growth and development, root morphology, stress response, DNA methylation and demethylation, gene silencing, cell proliferation, and hydraulic conductivity. Localisation evidence connects the product to the chloroplast thylakoid membrane, F1-F0 complex, respiratory chain complex I, chloroplast envelope, stroma, nucleolus, apoplast, plasmodesma, Golgi, and plant-type vacuole. Studies of related genes in other species link the family to cytoplasmic male sterility, protein content, and cold and oxidative stress tolerance.
