Switching on Production of Thiarubrines and Other Polyines by Transformation of Plant Tissue Cultures
About 6 years ago we planned to extend our research on the photobiology and the photobiochemistry of the characteristic polyines and related sulphur derivatives of the Asteraceae to studies on the biogenesis of these compounds and, in particular, the enzymes involved in these processes; no enzymes are known for thiophene, thiarubrine or polyine biosynthesis. For this purpose we decided to use cell and callus cultures of selected plant species. Unfortunately, we were not well prepared for the now well-known phenomenon of the switching off of secondary metabolism in such systems.
