TL;DR: The genome sequence of the oomycete Hyaloperonospora arabidopsidis is reported, an obligate biotroph and natural pathogen of Arabidopsis thaliana, which exhibits dramatic reductions in genes encoding RXLR effectors, proteins associated with zoospore formation and motility, and enzymes for assimilation of inorganic nitrogen and sulfur.

TL;DR: Access to the P. ultimum genome has revealed not only core pathogenic mechanisms within the oomycetes but also lineage-specific genes associated with the alternative virulence and lifestyles found within the pythiaceous lineages compared to the Peronosporaceae.
Journal ArticleDOI
A novel Arabidopsis-Colletotrichum pathosystem for the molecular dissection of plant-fungal interactions.
Richard J. O'Connell,Corentin Herbert,Surapareddy Sreenivasaprasad,Moustafa Khatib,Marie-Thérèse Esquerré-Tugayé,Bernard Dumas +5 more
TL;DR: The ability to genetically manipulate both partners in the interaction is an important advantage, and the Arabidopsis-Colletotrichum pathosystem should provide a valuable new model for dissecting plant-fungal interactions.
Journal ArticleDOI
Tissue-Specific Expression of Germin-Like Oxalate Oxidase during Development and Fungal Infection of Barley Seedlings
TL;DR: It is proposed that oxalate oxidase could have a role in plant defense through the production of H2O2 and is induced in barley leaves during infection by the fungus Erysiphe graminis f.
Journal ArticleDOI

TL;DR: Comparison of S. parasitica with plant pathogenic oomycetes suggests that during evolution the host cellular environment has driven distinct patterns of gene expansion and loss in the genomes of plant and animal pathogens.
