Deletion of the cpku80 gene in the chestnut blight fungus, Cryphonectria parasitica, enhances gene disruption efficiency
The cloning of the C. parasitica gene cpku80 that encodes a key component of the nonhomologous end joining DNA repair pathway and the construction of a corresponding deletion mutant strain is reported, which was indistinguishable from the parental wild-type strain EP155.

Cloned cyp1, a cyclophilin A-encoding gene in the phytopathogenic fungus Cryphonectria parasitica, showed that this gene was downregulated following infection by a virulence-attenuating hypovirus, and deletion resulted in reduced virulence when inoculated to chestnut stems.
Comparative vesicle proteomics reveals selective regulation of protein expression in chestnut blight fungus by a hypovirus.
While a few of the randomly selected differentially expressed proteins were in accordance with their transcription profiles, majority were not in agreement with their mRNA accumulation patterns, suggesting that an extensive post-transcriptional regulation may have occurred in the host fungus upon a hypovirus infection.

Functional annotation of unisequences revealed different gene expression patterns for wild-type and hypovirus-infected cultures at the sporulation stage and allowed the reconstruction of key C. parasitica signal transduction pathways conserved in the Sorbidaryomycetes.
Complexity of roles and regulation of the PMK1-MAPK pathway in mycelium development, conidiation and appressorium formation in Magnaporthe oryzae.
Functional groups and expression patterns of the regulated genes showed that gene members in the PMK1-MAPK pathway are associated with multiple signaling pathways and likely shares the mechanisms responsible for sexual conjugation and meiosis, which is affected by carbohydrate metabolism.

It is demonstrated that SAHH is required for virulence and multiple traits of phenotype in C. parasitica, by regulation of the expression of genes involved in key process of the cell.
The S. pombe mitochondrial transcriptome.
This work uncovers the complexity of a fungal mitochondrial transcriptome and provides a framework for future studies of mitochondrial gene expression using S. pombe as a model system.
dnm1 deletion blocks mitochondrial fragmentation in Δfzo1 cells
This study represents the first report of Fzo1 mediator of mitochondrial fusion in S. pombe, and finds that dnm1 mutations could both block mitochondrial fragmentation and rescue respiration growth defect in Δfzo1 single mutant cells.
Overexpression of Schizosaccharomyces pombe tRNA 3'-end processing enzyme Trz2 leads to an increased cellular iron level and apoptotic cell death.

The results suggest that trz2 overexpression may cause mitochondrial dysfunction, which is likely to lead to perturbation of iron homeostasis, ROS accumulation and induction of apoptotic cell death in S. pombe.
