Specific inhibitors of the MVA pathway (pravastatin) and the MEP pathway (fosmidomycin) were used to interfere with the biosynthetic flux which leads to the production of aphidicolin-like diterpene in leaf organ cultures of Scoparia dulcis. Treatment of leaf organs with fosmidomycin resulted in dose dependent inhibition of chlorophylls, carotenoids, scopadulcic acid B (SDB) and phytol production, and no effect on sterol production was observed. In response to the pravastatin treatment, a significant decrease in sterol and pertubation of SDB production was observed.
