Alkaloids in plants and root cultures of Atropa belladonna overexpressing putrescine N-methyltransferase.
Putrescine N-methyltransferase (PMT) is the first alkaloid-specific enzyme for nicotine and tropane alkaloid formation. The pmt gene from Nicotiana tabacum was fused to the CaMV 35S promoter and integrated into the Atropa belladonna genome. Transgenic plants and derived root cultures were analysed for gene expression and for levels of alkaloids and their precursors. Scopolamine, hyoscyamine, tr...
متن کاملAtropa Belladonna intoxication: a case report
Atropa belladonna is a poisonous plant also called deadly nightshade. Its roots, leaves and fruits contain alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion with other berries. Atropa belladonna acute intoxication is a severe condition, it's should be considered in the presence of anti-cholinergic toxidrome, the differe...
متن کاملOverexpression of tropinone reductases alters alkaloid composition in Atropa belladonna root cultures.
The medicinally applied tropane alkaloids hyoscyamine and scopolamine are produced in Atropa belladonna L. and in a small number of other Solanaceae. Calystegines are nortropane alkaloids that derive from a branching point in the tropane alkaloid biosynthetic pathway. In A. belladonna root cultures, calystegine molar concentration is 2-fold higher than that of hyoscyamine and scopolamine. In th...

The Solanaceae plants produce a variety of interesting biologically active products including the steroid alkaloids solanidine, nicotine and tropane alkaloids. Putrescine N-methyltransferase (PMT) is an enzyme that catalyses s-adenosylmethionine-dependent methylation of putrescine in one of the primary steps of nicotine and tropane alkaloids biosynthesis pathway. Two tobacco members of the AP2/...
