Epidemiological Role of Strains of Cryphonectria Parasitica Isolated from Hosts Other than Chestnut [link]Paper  doi  abstract   bibtex   
Cryphonectria parasitica is not common in the forests of the Emilia Romagna region of Italy on hosts other than chestnut. Three isolates with morphological cultural characteristics of C. parasitica were collected: two from infected bark of Quercits pubescens (EQ1 and EQ2) and one from Carpinus betulus (EC1). Pathogenicity tests on chestnut and crosses in vitro with strains of C. parasitica of different mating types confirmed that EQ1 and EQ2 are C. parasitica isolates, whereas EC1 seems to belong to a different species. Progeny analysis of crosses with the isolate EQ1 and a strain from chestnut showed the formation of new vegetative compatibility groups. Therefore hosts other than chestnut can contribute to increasing pathogen variability through recombination of the v-c genes.
