A cell suspension culture of
Tabernaemontana divaricata, that had lost alkaloid production, was still capable of producing a similar pattern of alkaloids as directly after its initiation. When fed with early precursors, such as tryptamine and loganin, 57% of the precursors was converted into indole alkaloids such as strictosidine, vallesamine,
O-acetylvallesamine and voaphylline. Apparently most of the cell factory has remained stable during the many years of subculturing. Only an early step of the biosynthesis the flux seems to be diverted to other pathways.
