✦ Synopsis
Transgenic hairy roots and shooty teratomas of Atropa belladonna L., Nicotiana tabacum L. and Solanum tuberosum L. were obtained with Agrobactetium Ti and Ri plasmids. The hairy roots of A. belIadonna, N. tabacum and S. tuberosum accumulated tropane alkaloids, nicotine alkaloids and steroidal alkaloids, respectively.
The shooty teratomas of these plant species failed to produce these alkaloids.
However, the shooty teratomas had the abilities to store and metabolize the alkaloids.
These results indicate that the biosynthesis and metabolism of these solanaceous alkaloids are regulated in correlation to tissue differentiation of the plants.
