The Top 10 fungal pathogens in molecular plant pathology.
A short resumé of each fungus in the Top 10 list and its importance is presented, with the intent of initiating discussion and debate amongst the plant mycology community, as well as laying down a bench-mark. Expand
Genome Expansion and Gene Loss in Powdery Mildew Fungi Reveal Tradeoffs in Extreme Parasitism
A group of papers analyzes pathogen genomes to find the roots of virulence, opportunism, and life-style determinants in plant pathogens, suggesting that most effectors represent species-specific adaptations. Expand
The wheat powdery mildew genome shows the unique evolution of an obligate biotroph
It is suggested that mildew genomes are mosaics of ancient haplogroups that existed before wheat domestication and there was no pronounced loss of genetic diversity upon formation of the new host bread wheat 10,000 years ago. Expand
Structure and evolution of barley powdery mildew effector candidates
It is hypothesized that the associated genes originated from an ancestral gene, encoding a secreted ribonuclease, duplicated successively by repetitive DNA-driven processes and diversified during the evolution of the grass and cereal powdery mildew lineage. Expand

It is argued here that the release of constraints on transposon activity is driven by the advantages conferred by the genetic variability that results from transposition, in particular by the creation and diversification of broad palettes of effector genes. Expand
Host-induced gene silencing in barley powdery mildew reveals a class of ribonuclease-like effectors.
Complementation analysis using silencing-insensitive synthetic cDNAs demonstrated that the ribonuclease-like BEC 1011 and 1054 are bona fide effectors that function within the plant cell, part of a gene superfamily unique to the powdery mildew fungi. Expand
Identification and structure of the mating-type locus and development of PCR-based markers for mating type in powdery mildew fungi.
The objectives of this study were to identify and sequence genes at the MAT1 locus in the grape powdery mildew fungus, Erysiphe necator, to develop a PCR-based marker for determining mating type, and to develop degenerate primers for amplification by PCR of conserved regions of mating-type idiomorphs in other powdery Mildew fungi.

Gene Expression Profiles of Blumeria graminis Indicate Dynamic Changes to Primary Metabolism during Development of an Obligate Biotrophic Pathogenw⃞
cDNA microarrays of Blumeria graminis f sp hordei transcript profiles during the asexual development cycle reveal the dynamics of global gene expression as the fungus germinates, penetrates, feeds onExpand
Hydrophobins and the interactions between fungi and plants.
Summary Hydrophobins are small proteins thought to be ubiquitous in filamentous fungi. They are usually secreted and are found on the outer surfaces of cell walls of hyphae and conidia where theyExpand
The hydrophobin HCf-1 of Cladosporium fulvum is required for efficient water-mediated dispersal of conidia.
Analysis of the mutant strains shows that HCf-1 confers hydrophilic character to the conidia and this facilitates the dissemination of conidia on the surface of water droplets. Expand
