Identification of novel genetic regions associated with resistance to European canker in apple.

Background: European canker, caused by the fungal pathogen Neonectria ditissima, is an economically damaging disease in apple producing regions of the world - especially in areas with moderate temperatures and high rainfall. The pathogen has a wide host range of hardwood perennial species, causing trunk cankers, dieback and branch lesions in its hosts. Although apple scion germplasm carrying partial resistance to the disease has been described, little is still known of the genetic basis for this quantitative resistance.

Susceptibility of Cider Apple Accessions to European Canker-Comparison between Evaluations in Field Planted Trees and Rapid Screening Tests.

European canker, caused by Bres., is an economically damaging fungal disease of apple. Breeding new cultivars with a high level of resistance to European canker is the main aim of apple breeding programs.

Variation in Host and Pathogen in the Interaction; toward an Understanding of the Genetic Basis of Resistance to European Canker.

Apple canker caused by the phytopathogenic fungus is an economically important disease, which has spread in recent years to almost all pome-producing regions of the world. is able to cross-infect a wide range of apple varieties and causes branch and trunk lesions, known as cankers. Most modern apple varieties are susceptible and in extreme cases suffer from high mortality (up to 50%) in the early phase of orchard establishment.

Draft Genome Sequence of a European Isolate of the Apple Canker Pathogen Neonectria ditissima.

The Sordariomycetes fungus Neonectria ditissima is a major pathogen of apples, causing canker on trees and fruit spoilage. We report here the draft genome sequence of a European strain isolated from cankerous tissue.
