Powdery mildew susceptibility and biotrophic infection strategies

LIFEGUARD proteins support plant colonization by biotrophic powdery mildew fungi

Pathogenic microbes manipulate eukaryotic cells during invasion and target plant proteins to achieve host susceptibility. BAX INHIBITOR-1 (BI-1) is an endoplasmic reticulum-resident cell death suppressor in plants and animals and is required for full susceptibility of barley to the barley powdery mildew fungus Blumeria graminis f.sp. hordei. LIFEGUARD (LFG) proteins resemble BI-1 proteins in te...

The Powdery Mildew Disease of Arabidopsis: A Paradigm for the Interaction between Plants and Biotrophic Fungi.

The powdery mildew diseases, caused by fungal species of the Erysiphales, have an important economic impact on a variety of plant species and have driven basic and applied research efforts in the field of phytopathology for many years. Although the first taxonomic reports on the Erysiphales date back to the 1850's, advances into the molecular biology of these fungal species have been hampered b...

The Arabidopsis RPW8 resistance protein is recruited to the extrahaustorial membrane of biotrophic powdery mildew fungi.

Correlation of defense gene induction defects with powdery mildew susceptibility in Arabidopsis enhanced disease susceptibility mutants.

We investigated the relative importance of specific Arabidopsis thaliana genes in conferring resistance to bacterial versus fungal pathogens. We first developed a pathosystem involving the infection of Arabidopsis accession Columbia with a virulent isolate of the obligate biotrophic fungal pathogen Erysiphe orontii. E. orontii elicited the accumulation of mRNAs corresponding to the defense-rela...
