Loss-of-function mutations in chitin responsive genes show increased susceptibility to the powdery mildew pathogen Erysiphe cichoracearum.

Chitin is a major component of fungal walls and insect exoskeletons. Plants produce chitinases upon pathogen attack and chito-oligomers induce defense responses in plants, though the exact mechanism behind this response is unknown. Using the ATH1 Affymetrix microarrays consisting of about 23,000 genes, we examined the response of Arabidopsis (Arabidopsis thaliana) seedlings to chito-octamers an...

Aggressiveness Variation in Czech Isolates of Erysiphe cichoracearum Pathotype AB1B2CCm

Introduction. Erysiphe cichoracearum /Ec/ is the predominating powdery mildew species on cucurbits in the Czech Republic (5). Its occurrence and spreading on cucurbits can be influenced not only by virulence, but also by aggressiveness of isolates within natural pathogen populations. Both forms of pathogenicity have an impact on plant cultivation and protection and should be considered in resis...

a contribution to the study of erysiphaceae (ascomycota: erysiphales) in iran

in the framework of a study on the powdery mildew fungi in iran, several infected plant specimens were collected from around the country during 2001-2009. based on the results of the study erysiphe quercicola on quercus sp. and e. malvae on malva sp., golovinomyces ambrosiae on helianthus spp., golovinomyces fischeri on senecio glaucus, are the newly reported for iranian mycobiota. in addition,...

Genome-wide expression profiling Arabidopsis at the stage of Golovinomyces cichoracearum haustorium formation.

Compatibility between plants and obligate biotrophic fungi requires fungal mechanisms for efficiently obtaining nutrients and counteracting plant defenses under conditions that are expected to induce changes in the host transcriptome. A key step in the proliferation of biotrophic fungi is haustorium differentiation. Here we analyzed global gene expression patterns in Arabidopsis thaliana leaves...
