Comparative genomics reveals mobile pathogenicity chromosomes in Fusarium
Comparison of genomes of three phenotypically diverse Fusarium species revealed lineage-specific genomic regions in F. oxysporum that include four entire chromosomes and account for more than one-quarter of the genome, putting the evolution of fungal pathogenicity into a new perspective.

Translocation of Magnaporthe oryzae Effectors into Rice Cells and Their Subsequent Cell-to-Cell Movement[W][OA]
The authors imaged fungal transformants secreting fluorescent effector fusion proteins in first-invaded rice cells. Two effectors that accumulated in biotrophic interfacial complexes were…
A Novel Pathogenicity Gene Is Required in the Rice Blast Fungus to Suppress the Basal Defenses of the Host
It is demonstrated that a novel pathogenicity gene, DES1, in Magnaporthe oryzae regulates counter-defenses against host basal resistance, and it is suggested that DES1 functions as a novel routeogenic gene that regulates the activity of fungal proteins, compromising ROS-mediated plant defense.

The avirulence (AVR) gene AVR-Pita in Magnaporthe oryzae prevents the fungus from infecting rice cultivars containing the resistance gene Pi-ta, which is a member of a gene family that may be unique to the M. grisea species complex.
Homeobox Transcription Factors Are Required for Conidiation and Appressorium Development in the Rice Blast Fungus Magnaporthe oryzae
Transcriptional analyses suggest that the functioning of M. oryzae homeobox TFs is mediated through the regulation of gene expression and is affected by cAMP and Ca2+ signaling and/or MAPK pathways.
A putative MAP kinase kinase kinase, MCK1, is required for cell wall integrity and pathogenicity of the rice blast fungus, Magnaporthe oryzae.
The results suggest that MCK1 is an MAPKKK involved in maintaining cell wall integrity of M. oryzae, and that remodeling of the cell wall in response to host environments is essential for fungal pathogenesis.
Genome-wide profiling of DNA methylation provides insights into epigenetic regulation of fungal development in a plant pathogenic fungus, Magnaporthe oryzae
It is found that DNA methylation occurs in and around genes as well as transposable elements and undergoes global reprogramming during fungal development, suggesting that it may have acquired new roles other than controlling the proliferation of TEs.
