| Research Abstract |
To elucidate the mechanism of the high aluminum(Al) resistance of a Myrtaceae tree, Eucalyptus camaldulensis, we investigated the structure and characteristics of a novel Al-binding compound in this species. The structure of the Al-binding compound isolated from E. camaldulensis was identified as a hydrolyzable tannin, oenothein B. This compound(1) had a high Al-binding ability,(2) was not detected in Al-sensitive tree species, and(3) was increased in its content in root of E. camaldulensis by Al treatment. These results suggest that complex formation between oenothein B and Al detoxifies Al in root of E. camaldulensis, which contributes to its high Al resistance.
