Potato tuber cell expansion-inducing activity of stereochemically restricted JA analogs

Biosci Biotechnol Biochem. 2009 Aug;73(8):1872-6. doi: 10.1271/bbb.90148. Epub 2009 Aug 7.


Stereochemically restricted analogues of C-7 substituted 7-epi-jasmonate, together with 12-hydroxy jasmonic acid, 12-hydroxy jasmonic acid glucoside, and jasmonic acid conjugated with L-isoleucine (JA-Ile), were synthesized and then tested for potato tuber cell expansion-inducing activity. JA-Ile showed almost the same activity as JA, while the C-7 substituted 7-epi-jasmonates exhibited weaker activity than JA and showed an antagonist effect against JA.
