ATPD — Pisum sativum

Summary

PsATPD (PSAT6G185760) in garden pea (Pisum sativum, chromosome 6LG2) encodes a protein with ATP_synth_F0_dsu_mt and ATP_synth_F0_dsu_sf_mt domains, and is annotated with proton-transporting ATP synthase activity, rotational mechanism, and copper, zinc, and protein binding. The gene is associated with proton motive force-driven ATP synthesis, nitrogen fixation, nodulation, leaf vascular tissue pattern formation, auxin and brassinosteroid signaling, and osmotic response. It is linked to osmotic stress tolerance, lateral root development, brassinosteroid sensitivity, abnormal leaf venation with reduced vein number, and reduced root length. The product localizes to the F1-F0 complex, thylakoid, chloroplast thylakoid membrane, mitochondria, cytosol, plasmalemma, nucleolus, and plant-type vacuole. Studies of related genes in other species connect the family to potassium content, cytoplasmic male sterility, high temperature stress response, photochemical quenching, and plant growth.
