Effect of methyl Jasmonate on the Production of sesquiterpene lactones in the hairy root culture of lactuca virosa L.

摘要

Hairy roots of Lactuca virosa L. transformed with Agrobacterium rhizogenes and treated with methyl jasmonate, are ca- pable of producing sesquiterpene lactones-crepidiaside B and lactuside A in amounts higher than in untreated roots. An HPLC analysis showed the highest content of crepidiaside B after 24 hours of methyl jasmonate treatment (60/100 above the Control). The increase in the content of lactuside A was relatively small and reached 27/100 after 48 hours of the treatment, in Comparison with the control.
