It has been reported that rol plant oncogenes located in Ri-plasmids of Agrobacterium rhizogenes activated synthesis of secondary metabolites in the transformed plant cells. The activator mechanism is still unknown. In this work, we studied whether the NADPH oxidase-signaling pathway, which
The transformation of Rubia cordifolia L. cells by the 35S- rolB and 35S- rolC genes of Agrobacterium rhizogenes caused a growth inhibition of the resulting cultures and an induction of the biosynthesis of anthraquinone-type phytoalexins. Inhibitor studies revealed a striking difference between the
