Rubidium Transport in Membrane Vesicles from the Halophyte Suaeda maritima

By C D Field, T J Flowers and J L Hall

Abstract

The uptake and efflux of Rb+ by membrane vesicles isolated from shoots of the halophyte Suaeda maritima have been investigated. Uptake came to an apparent equilibrium after 1 h and the initial rate of uptake was considerably slower than that reported for bacterial membrane vesicles Additions of ATP reduced both Rb+ uptake and the half-time for loss in efflux experiments, although this effect was not specific for ATP and probably was not associated with energy transfer The permeability coefficient for Rb+ was calculated to be between 0 1 and 0 3 × 10−2 cm s−1. The value of membrane vesicles in ion transport studies in plants is discussed
