ATPB — Beta vulgaris subsp. vulgaris

Summary

BvATPB (ATPB) on sugar beet chromosome 140133 encodes a protein with ATPase alpha/beta chains and P-loop_NTPase domains, and is associated with EC 7.1.2.2 and proton-transporting ATP synthase activity, rotational mechanism. The gene is associated with proton-motive-force-driven mitochondrial ATP synthesis, chloroplast thylakoid membrane and envelope localisation, and the F1-F0 complex. It has been linked to phosphoglyceride, inositol phosphate, glutathione and phosphate metabolism, tRNA charging, brassinosteroid-mediated signalling, and upregulation of long-day photoperiodism and flowering. Associations include plant stress response, flowering time, root morphology, and growth and development traits, as well as phenotypes for flowering time, meiosis, DNA methylation and demethylation, gene silencing, cell proliferation, syncytium size, hydraulic conductivity and stress tolerance. Studies of related genes in other species link the family to cytoplasmic male sterility, protein content, and cold and oxidative stress responses.
