Interactions between Ca, Na, and K inSalicornia virginicaand barley roots under saline conditions: multi- compartment transport box experiment

Effects of metabolic inhibitors on Na+stimulated K+uptake in salicornia virginica roots: Possibility of metabolic coupling of the transport

“…It had been previously reported (Kawasaki and Moritsugu 1987;Sopandie et al 1990) that the distribution pattern of ions in an excised plant root can be classified qualitatively as indicated in Fig. 1.…”

“…Control treatments for this study consisted of a similar addition of 95% ethanol. The present investigation was carried out according to the procedure described previously (Kawasaki and Moritsugu 1987;Sopandie et al 1990). …”

“…In the present study, multi-compartment transport boxes were used to determine the mobility of the ion in the roots (Kawasaki et al 1983;Kawasaki and Moritsugu 1987;Sopandie et al 1990). …”

“…Salicornia roots were prepared from plant cuttings grown in solution culture with the addition of 50 mM NaCI prior to the excision of roots, as described previously (Sopandie et al 1990). In the present study, multi-compartment transport boxes were used to determine the mobility of the ion in the roots (Kawasaki et al 1983;Kawasaki and Moritsugu 1987;Sopandie et al 1990).…”

“…Regarding the ionic interactions in the roots of the halophyte Salicornia virginica, it has been previously reported that high concentrations of NaC1 stimulated the uptake of K + in the presence of Ca 2+, though the mechanism underlying this stimulating effect of Na + remains largely unknown (Sopandie et al 1990). The results obtained led us to examine the possibility of a metabolic linkage to this movement of K + into the roots of Salicornia under saline conditions.…”
