Biotransformation of the potato stress metabolite, solavetivone, by cell suspension cultures of two solanaceous and three non-solanaceous species.

Cell suspension cultures of several plant species which were exogenously supplied solavetivone accumulated four hydroxylated derivatives. Only solanaceous cell cultures converted exogenously supplied solavetivone to sesquiterpenoid compounds identified with the plant response to biotic stress. Failure of potato cell cultures to make these compounds under biotic stress may be linked to their inability to produce adequate levels of solavetivone.
