Selectivity of Alkali Cation Influx Across the Plasma Membrane of Oat Roots: Cation Specificity of the Plasma Membrane ATPase 1
AUTOR(ES)
Sze, Heven
RESUMO
Influx of alkali cations (Li+, Na+, K+, Rb+, Cs+) across plasma membranes of cells of excised roots of Avena sativa cv. Goodfield was selective, but different, in the absence and in the presence of 1 mm CaSO4. Ca2+ reduced the influx rates of all of the alkali cations—especially Na+ and Li+. Transport selectivity changed as the external concentrations of the alkali cations increased.
