[Role of elements and physiologically active compounds in the regulation of synthesis and accumulation of indole alkaloids in Catharanthus roseus L].
Effects of various elements (Co, Ni, Zn, W, Mn, Cr, B, Mo, Fe, and V), natural and synthetic auxins, cytokinins, and gibberellin on biosynthesis and accumulation of indole alkaloids was studied at increasing concentrations in the model system of Madagascar periwinkle seedlings (Catharanthus roseus L.). The main types of concentration dependences for the effect of physiologically active compounds under study were evaluated. A possible mechanism of the influence of Zn and auxin on this process was partly clarified. The compounds were shown to modulate various stages in the biosynthesis of monomeric indole alkaloids (catharanthine and vindoline).
