    Alkaloid biosynthesis in Nicotiana spp. with different alkaloid composition

    BUSH L.P.; FANNIN F.F.; HANRAHAN M.S.; NICHOLAS K.N.
    University of Kentucky, Dept. of Agronomy, Lexington, KY, USA
    Biosynthetic schemes have been proposed for tobacco alkaloids based upon incorportation of suspected precursors, but the addition of these precursors has not resulted in increased alkaloid accumulation in plants. Putrescine, cadaverine and nicotinic acid ...
