Abstract: | Leaves of the wilty pepper mutant, scabrous diminutive, accumulatemore Na+ than those of the normal genotype, when both grow inmedium containing N+. It seems that the regulation of Na+ fluxin the mutant root was modified. Net uptake of Na+ was muchhigher and efflux of 22Na+ was lower in the mutant roots thanin the normal ones. Two possible explanations for these differencesbetween mutant and normal plants are discussed, namely (a) achange in membrane permeability and (b) a change in the mechanismof Na+ extrusion. |
