Abstract

Leaves of the wilty pepper mutant, scabrous diminutive, accumulate more Na+ than those of the normal genotype, when both grow in medium containing N+. It seems that the regulation of Na+ flux in the mutant root was modified. Net uptake of Na+ was much higher and efflux of 22Na+ was lower in the mutant roots than in the normal ones. Two possible explanations for these differences between mutant and normal plants are discussed, namely (a) a change in membrane permeability and (b) a change in the mechanism of Na+ extrusion.
