title: Methyl Jasmonate Induces Enhanced Podophyllotoxin Production in Cell Cultures of Thracian Flax (Linum thracicum ssp. thracicum).
abstract: The Linum thracicum ssp. thracicum cell lines developed in this study are a feasible source for the sustainable production of podophyllotoxin, a lignan with an aryltetralin skeleton that is used for the manufacture of the chemotherapeutic drugs etopophos and teniposide. We used mass spectrometry to confirm the presence of the aryltetralin lignan in the thracian flax cell cultures. Next, we explored how changes in the culture medium influenced the podophyllotoxin content. Out of six developed cell lines, four were selected for further experiments and challenged with elicitors. The selected cell lines clustered into two groups: developed in full strength medium (Li) vs developed in half strength medium (HS). While podophyllotoxin production in the Li cell lines was boosted by 80% upon administration of the elicitor methyl jasmonate, the HS lines produced high amounts of the target metabolite triggered by reduced concentration of nutrients and were only slightly influenced by the elicitor.
