Abstract
Abstract The absorption of 99‐Mo by excised tobacco, Nicotiana tabacum L. c.v. KY‐14, roots was examined. Lowered temperature, anaerobic conditions and various inhibitors of oxidative phosphorylation decreased the absorption of Mo, suggesting that the absorption of Mo was metabolism‐dependent. Similar results were obtained with the absorption of 86‐Rb. The absorption of 99‐Mo decreased exponentially with an increase in pH. The apparent Km for the absorption of Mo was 15 μM, although at high concentrations of Mo, the absorption of Mo occurs primarily by passive processes.
