Field properties and ion uptake of wheat and oat: are they expressed in the modulatory influences of ions on membrane ATPases? [transport, anion, cation, carrier, chloride, hydrogen carbonate, potassium, calcium, magnesium, manganese]

The CaATPase activities of microsomal fractions (10,000 g × 15 min - 30,000 g × 60 min) of roots from wheat (Triticum aestivum L. cv. Svenno) and oat (Avena sativa L. cv. Brighton) are inhibited by HCO₃⁻ and a Cl⁻; and there is no effect by K⁺ on the CaATPase. If the ATPase is activated by Mg²⁺ or b...
