Enhancement of taxane production in cell suspension culture of Corylus avellana L. Kalınkara by elicitation and precursor feeding

Doğan, Ahmet

Paclitaxel (trademark Taxol®) is the most effective chemotherapeutic agent against a wide range of cancers. Hazelnut (Corylus avellana L.) cell culture is a promising and inexpensive strategy for producing paclitaxel and related taxanes. This study evaluated the effect of elicitation and taxane precursor feeding for the enhancement of taxanes in a Turkish hazelnut (C. avellana cv. ‘Kalınkara’) cell suspension culture. Elicitor methyl jasmonate (100, 200 and 300 µmol L−1) and precursor phenylalanine (3μmol, 3 and 6 mmol L−1) were tested in cell suspension cultures. While methyl jasmonate increased the accumulation of taxanes, especially cephalomannine, via induction of the paclitaxel biosynthetic pathway, phenylalanine slightly induced the conversion of 10-deacetylbaccatin III and baccatin ...
