Outline of Final Research Achievements |
Eucalyptus camaldulensis exhibits high resistance to aluminum toxicity which is a major factor limiting plant growth on acid soils, and its root contains a novel type of aluminum detoxifying ligand, oenothein B. (1) Oenothein B concentration in roots was correlated with Al resistance of five tree species. (2) Oenothein B could bind and detoxify aluminum. (3) Oenothein B binds to aluminum in competition with organic acids, and binds predominantly to aluminum. Taken together, detoxification of aluminum by oenothein B in root of E. camaldulensis contributes to its high aluminum resistance.
