Abstract |
Virulence (vir) gene expression of Agrobacterium tumefaciens is activated by plant phenolic compounds such as alpha-hydroxyacetosyringone (HOAS), acetosyringone (AS), methyl syringate, coniferyl alcohol and sinapyl alcohol. Inositol was found to be a potentiating factor of vir-inducing activity, which enhanced the vir-inducing activity of AS and HOAS in a synergistic manner, in particular at a low concentrations of AS and HOAS. Of the other sugars tested D-glucose, L- rhamnose, D-xylose and D-galacturonic acid, the main components of plant cell wall polysaccharides, remarkedly potentiated the vir-inducing activity of AS, indicating the cooperative action of the signal compounds and sugars in Agrobacterium infection to plants.
