The effect of fusicoccin on the plasmalemma H+-ATPase has been investigated in a membrane fraction from 24 h old radish seedlings, in which Mg:ATP-dependent H+-transport is mediated only by the plasmalemma H+-ATPase. Fusicoccin stimulated the plasmalemma H+-ATPase - i.e. Mg:ATP-dependent intravesicular acidification, hyperpolaryzation of delta psi and ATPase activity -, when these activities were measured at the physiologically relevant pHs of 7.3 to 7.6. No effect of FC on the plasmalemma H+-ATPase was evident at pH 6.6.
