; Grape downy mildew is caused by Plasmopara viti-cola, an obligate biotrophic oomycete and a major path-ogen of grapevine. Studying obligate biotrophic patho-gens is difficult as they cannot grow without their host. We therefore attempted to develop a method where the pathogen could be visualized and quantified in planta without killing the host plant. To this end P. viticola was transformed with the marker gene gfp coding for the green fluorescent protein. Various transformation methods, namely electroporation, particle bombard-ment and transformation with Agrobacterium tume-faciens were applied. Although some methods yielded positive transformation events, no stable strain of P. viticola expressing gfp could be generated. Using the electroporation method, we obtained transient P. viti-cola transformants expressing gfp over 4 generations. In contrast, particle bombardment failed in transform-ing P. viticola. Transformation with A. tumefaciens had a low efficiency, only some structures were fluorescent and fluorescence was never observed in the subsequent generations. - PublicationMétadonnées seulementReverse genetic methods in research on induced resistance of grapevine: development of a vector for shRNA production to induce gene silencing(2006)
