title: [Effect of salicylic acid on the proton translocation activity of plasmalemma of potato tuber cells].
abstract: Action of salicylic acid (SA) on the activity of membrane bound H(+)-ATPase and passive proton permeability of plasmalemma membrane vesicles (PMV) from parenchyma cells of potato tubers was detected. A correlation between SA action and germination of tubers and activity of plasmalemma H(+)-ATPase was revealed: the application of growth-stimulating concentrations of SA (10(-10)-10(-8) M) in the system in vitro resulted in activation of plasmalemma H(+)-ATPase, while the utilization of growth-inhibiting concentrations (10(-4), 10(-5) M) provoked inhibition of the enzyme activity. Addition of jasmonic acid (JA) to the incubation mix resulted in increase of SA effect on the accumulation of H+ in PMV.
