Draft genome sequences for and canker pathogens of and in West Virginia.

The fungal genus contains many phytopathogenic species currently impacting forests and fruit trees worldwide. Despite their importance, a majority of spp. lack sufficient genomic resources to resolve suspected cryptic species.

Characterization of mating type genes in heterothallic species, with emphasis on , and .

and are canker pathogens involved in an insect-fungus disease complex of American beech () in North America commonly known as beech bark disease (BBD). In Europe, both and are involved in BBD on European beech (). Field observations across the range of BBD indicate ascospores to be the dominant spore type in the environment.

Morphological and Phylogenetic Resolution of and , Emerging Canker Pathogens of Oak ( spp.), in the United States.

In Mediterranean Europe and the United States, oak species ( spp.) have been in various states of decline for the past several decades. Several insect pests and pathogens contribute to this decline to varying degrees, including , spp.

Diversity and function of fungi associated with the fungivorous millipede, .

Fungivorous millipedes (subterclass Colobognatha) likely represent some of the earliest known mycophagous terrestrial arthropods, yet their fungal partners remain elusive. Here we describe relationships between fungi and the fungivorous millipede, . Their fungal community is surprisingly diverse, including 176 genera, 39 orders, four phyla, and several undescribed species.

Psychoactive plant- and mushroom-associated alkaloids from two behavior modifying cicada pathogens.

Entomopathogenic fungi routinely kill their hosts before releasing infectious spores, but a few species keep insects alive while sporulating, which enhances dispersal. Transcriptomics- and metabolomics-based studies of entomopathogens with post-mortem dissemination from their parasitized hosts have unraveled infection processes and host responses. However, the mechanisms underlying active spore transmission by Entomophthoralean fungi in living insects remain elusive.

Enhanced hypovirus transmission by engineered super donor strains of the chestnut blight fungus, Cryphonectria parasitica, into a natural population of strains exhibiting diverse vegetative compatibility genotypes.

Horizontal transmission of virulence attenuating hypoviruses of Cryphonectria parasitica is restricted by an allorecognition system termed vegetative incompatibility (vic). A super donor formulation of two engineered C. parasitica strains (SD328/SD82) with gene disruptions at four of six vic loci transmitted hypovirus to strains in the laboratory independent of vic genotype.

Multilocus PCR Assays Elucidate Vegetative Incompatibility Gene Profiles of Cryphonectria parasitica in the United States.

Chestnut blight is a devastating disease of Castanea spp. Mycoviruses that reduce virulence (hypovirulence) of the causative agent, Cryphonectria parasitica, can be used to manage chestnut blight. However, vegetative incompatibility (vic) barriers that restrict anastomosis-mediated virus transmission hamper hypovirulence efficacy.
