The effects of anions on inorganicpyrophosphate-dependent H+-transport in isolated tonoplast vesicles from oat (Avena sativa L.) roots were determined. Both fluorescent and radioactive probes were used to measure formation of pH gradients and membrane potential in the vesicles. Pyrophosphate hydrolysis by the H+-translocating pyrophosphatase was unaffected by anions. Nonetheless, some anions (Cl-, Br- and NO3-) stimulated H+-transport while others (malate, $$SO_4 ^{2 - }$$ and iminodiacetate… CONTINUE READING
