Diversity of Cryphonectria parasitica populations from the Carpathian Basin [PDF]

Acta Microbiologica et Immunologica Hungarica, 2015
The ascomycetous fungus Cryphonectria parasitica (Murr.) is one of the most important fungal pathogens of chestnut (Castanea sativa Mill.), causing chestnut blight. It is originated from Eastern Asia and was introduced into North America, and later into Europe. Almost 100 C.

The Morphology and the Biological Control of Cryphonectria parasitica

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Agriculture, 2012
Cryphonectria parasitica  (Murr.) Bar [syn. Endothia parasitica (Murr. And.] (anamorf: Endothiella sp .) is the causal agent of chestnut bark disease or chestnut blight, disease which produced great damages throughout the world, for example, in Europe, the European chestnut tree ( Castanea sativa (P.) Mill) was heavily affected.

Cpkk1, MAPKK of Cryphonectria parasitica, Is Necessary for Virulence on Chestnut [PDF]

Phytopathology®, 2010
The role of Cpkk1, a mitogen-activated protein kinase from Cryphonectria parasitica, was investigated by generating a number of mutant strains that overexpress, under the control of the cryparin promoter, both the wild-type protein and its allele with an extensive deletion in the catalytic domain.

G Protein α Subunit Genes Control Growth, Development, and Pathogenicity of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
Three G protein α subunit genes have been cloned and characterized from Magnaporthe grisea: magA is very similar to CPG-2 of Cryphonectria parasitica; magB is virtually identical to CPG-1 of Cryphonectria parasitica, to gna1 of Neurospora crassa, and to ...
