Tonoplast: The Controlling Site for the in Vitro Solute Transport in Developing Soybean Cotyledons
In vitro accumulation into developing soybean cotyledons have been shown to be energy dependent, and is an active uptake process (Lichtner and Spanswick, a and b; Thorne, 1982; Lin et al., 1984; Schmitt et al., 1984; Lin, 1985 b). Studies on the concentration dependency, interference of external pH, and effect of several metabolic inhibitors on both sugar and amino-acid uptake into excised intact cotyledons and isolated protoplasts have provided circumstantial evidences for the involvement of a proton cotransport mechanism (Lichtner and Spanswick, 1981 a and b; Thorne, 1982, Lin et al., 1984; Schmitt et al., 1984; Lin, 1985 b).
