| Abstract: | Cadaverine (1–10 mM) stimulated the production of anabasine by hairy root cultures of Nicotiana rustica transformed with Agrobacterium rhizogenes. In control cultures, nicotine accounted for at least 70–80% of the total alkaloid produced, whereas in cultures supplemented with 5 mM cadaverine about two-thirds of the alkaloid was anabasine and nicotine production was markedly diminished. Putrescine and agmatine caused some stimulation of alkaloid production, but the ratio of nicotine to anabasine was essentially unaffected. Lysine caused no substantial increase in anabasine formation. |
