Comparative toxicity of Al3+, Yb3+, and La3+to root-tip cells differing in tolerance to high Al3+in terms of ionic potentials of dehydrated trivalent cations

Abstract
In order to analyze the binding pattern of Al3+ to and the mechanism(s) of Al3+ toxicity in root-tips, we compared the responses to trivalent metal ions (Al3+, Yb3+, and La3+) of root-tip cells differing in Al tolerance. Results were as follows: The conclusions were as follows:
