ATPB — Beta vulgaris subsp. vulgaris

Summary

BvATPB (ATPB) on sugar beet chromosome 92065 encodes a protein with ATP_synth_F1_bsu, ATPase_F1/V1_b/a_C, ATPase alpha/beta chains, ATP-synt_VA_C, ATPase_F1/V1/A1_a/bsu_nucl-bd, and P-loop_NTPase domains. The gene is associated with proton motive force-driven mitochondrial ATP synthesis, phosphoglyceride and inositol phosphate metabolism, tRNA charging, and glutathione metabolism. It is linked to upregulation of long-day photoperiodism and flowering, brassinosteroid-mediated signalling, and RNA-directed DNA methylation. The product localises to the chloroplast thylakoid membrane, envelope and stroma, as well as the F1-F0 complex, respiratory chain complex I, apoplast, nucleolus, plant-type vacuole, Golgi complex and plasmodesmata. Associations with plant stress response, flowering time, root morphology, and growth and development traits have been reported. Related genes in other species are linked to cytoplasmic male sterility, protein content, and cold and oxidative stress responses.
