| Abstract:
Parsley cell cultures are known to respond to fungal elicitor with an accumulation of furanocoumarin phytoalexins, whereas UV-irradiation induces the synthesis of flavonoid glycosides. In this report we summarize the influence of ozone on the two stress pathways in parsley plants at the levels of secondary metabolism, enzyme activities as well as transcript amounts. Ozone treatment resulted in the simultaneous induction of both pathways of phenylpropanoid metabolism ("cross induction"). | |
