Abstract
In response to infection, Malinae produce biphenyls and dibenzofurans as phytoalexins.
In spite of the economic importance of the Malinae biosynthesis of their phytoalexins is poorly understood.
The key enzyme which forms the carbon skeleton is biphenyl synthase (BIS). This protein was immunochemically detected in Sorbus aucuparia cell cultures treated with an autoclaved suspension of Erwinia amylovora. Immunofluorescence appeared as discrete globules and localized at the surface of the cells, suggesting association of BIS with plasmodesmata.
