Fifty-three polymorphic microsatellite loci in the chestnut blight fungus, Cryphonectria parasitica
نویسندگان
چکیده
We report on 53 microsatellite loci for use in population genetic or linkage mapping studies in Cryphonectria parasitica . In 40 isolates collected from throughout the Northern Hemisphere, the number of alleles per locus ranged from two to 14 (mean 5.17) with gene diversity values ranging from 0.049 to 0.859 (mean 0.437). Samples from Asia were more diverse than those from Europe and North America. Most of the markers (48 of 53) were developed from an expressed sequence tag library, and hence, offer the opportunity to examine population structure or provide genome location information for specific expressed genes vs. anonymous genomic regions.

Molecular Characterization of Vegetative Incompatibility Genes That Restrict Hypovirus Transmission in the Chestnut Blight Fungus Cryphonectria parasitica
Genetic nonself recognition systems such as vegetative incompatibility operate in many filamentous fungi to regulate hyphal fusion between genetically dissimilar individuals and to restrict the spread of virulence-attenuating mycoviruses that have potential for biological control of pathogenic fungi. We report here the use of a comparative genomics approach to identify seven candidate polymorph...
متن کاملInvasion history and demographic pattern of Cryphonectria hypovirus 1 across European populations of the chestnut blight fungus
We reconstructed the invasion history of the fungal virus Cryphonectria hypovirus 1 (CHV-1) in Europe, which infects the chestnut blight fungus Cryphonectria parasitica. The pattern of virus evolution was inferred based on nucleotide sequence variation from isolates sampled across a wide area in Europe at different points in time. Phylogeny and time estimates suggested that CHV-1 was introduced...
متن کاملVegetative incompatibility loci with dedicated roles in allorecognition restrict mycovirus transmission in chestnut blight fungus.
Vegetative incompatibility (vic), a form of nonself allorecognition, operates widely in filamentous fungi and restricts transmission of virulence-attenuating hypoviruses in the chestnut blight fungus Cryphonectria parasitica. We report here the use of a polymorphism-based comparative genomics approach to complete the molecular identification of the genetically defined C. parasitica vic loci wit...
متن کاملA Hydrophobin of the chestnut blight fungus, Cryphonectria parasitica, is required for stromal pustule eruption.
Hydrophobins are abundant small hydrophobic proteins that are present on the surfaces of many filamentous fungi. The chestnut blight pathogen Cryphonectria parasitica was shown to produce a class II hydrophobin, cryparin. Cryparin is the most abundant protein produced by this fungus when grown in liquid culture. When the fungus is growing on chestnut trees, cryparin is found only in the fungal ...
متن کاملAphelenchoides hylurgi as a carrier of white, hypovirulent Cryphonectria parasitica and its possible role in Hypovirulence spread on blight-controlled american chestnut trees.
Individual nematodes were isolated from American chestnut blight-controlled cankers to determine if they were carriers of biocontrol (hypovirulent) isolates of the chestnut blight fungus, Cryphonectria parasitica. These hypovirulent isolates have a white fungal colony phenotype due to infection by the virus CHV1. Of 1,620 individual Aphelenchoides hylurgi isolated, 29.4% carried propagules of t...
