By the compartmental analysis method of MacRobbie and Dainty, and Pitman, estimates of K(+), Na(+), and Cl(-) concentrations and fluxes were obtained for the cytoplasm and vacuole of coleoptile cells of oat, Avena sativa L. cv. Victory. Double labeling was used in experiments with (42)K plus (22)Na and with (42)K plus (36)Cl in a complete nutrient solution. At the plasmalemma, according to the Ussing-Teorell flux ratio equation, Na(+) is pumped out and Cl(-) is actively transported inward. The… CONTINUE READING
