From Endophyte Community Analysis to Field Application: Control of Apple Canker (Neonectria ditissima) with Epicoccum nigrum B14-1

Agriculture, 2023
Apple canker, caused by Neonectria ditissima (Tul. and C. Tul.) Samuels and Rossman, is a major disease of apples (Malus domestica) worldwide. N. ditissima infects through natural and artificial wounds.

Detecting the asymptomatic colonization of apple branches by Neonectria ditissima, causing European canker of apple [PDF]

European Journal of Plant Pathology, 2023
Abstract European canker is one of the most devastating fungal diseases of apple in most temperate regions. The causal agent, Neonectria ditissima, infects trees through wounds in the bark forming cankers that girdle the stem and eventually cause tree death.

Assessment of diversity and genetic relationships of Neonectria ditissima: the causal agent of fruit tree canker [PDF]

Hereditas, 2016
Neonectria ditissima is one of the most important fungal pathogens of apple trees, where it causes fruit tree canker. Information about the amount and partitioning of genetic variation of this fungus could be helpful for improving orchard management strategies and for breeding apple cultivars with high levels of genetically determined resistance.

Methods for the Quantification of Resistance of Apple Genotypes to European Fruit Tree Canker Caused by Neonectria ditissima [PDF]

Plant Disease, 2017
European fruit tree canker, caused by Neonectria ditissima, is an important disease of pome fruit worldwide. Apple cultivars differ in their levels of susceptibility to N. ditissima. In order to design an effective plant resistance test, we examined the effectiveness of two resistance parameters: infection frequency and lesion growth.

Reference genes for gene expression analysis in the fungal pathogen Neonectria ditissima and their use demonstrating expression up-regulation of candidate virulence genes.

PLoS ONE, 2020
European canker, caused by the necrotrophic fungal phytopathogen Neonectria ditissima, is one of the most damaging apple diseases worldwide. An understanding of the molecular basis of N. ditissima virulence is currently lacking.

The interplay between scion genotype, root microbiome, and Neonectria ditissima apple canker [PDF]

FEMS Microbiology Ecology
Abstract Severity of European apple canker caused by Neonectria ditissima can vary between locations and apple genotypes. We investigated how location, cold storage/planting season, and apple scion genotype affect root-associated microbial communities.

Fungicide Sensitivity in the European Canker Fungus, Neonectria ditissima

Erwerbs-Obstbau, 2023
AbstractNeonectria ditissima is one of the most serious pathogens of apple trees in temperate climatic zones, causing bark canker as well as pre- and post-harvest fruit rots. Control of fruit rots in particular is hampered by uncertainty about the sensitivity to, and efficacy of, available fungicides. Using 43 N.

Pathogen and Endophyte Assemblages Co-vary With Beech Bark Disease Progression, Tree Decline, and Regional Climate

Frontiers in Forests and Global Change, 2021
Plant–pathogen interactions are often considered in a pairwise manner with minimal consideration of the impacts of the broader endophytic community on disease progression and/or outcomes for disease agents and hosts.

Quantitative trait loci associated with apple endophytes during pathogen infection

Frontiers in Plant Science, 2023
The plant phyllosphere is colonized by microbial communities that can influence the fitness and growth of their host, including the host’s resilience to plant pathogens.There are multiple factors involved in shaping the assemblages of bacterial and ...

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

Plants, 2022
European canker, caused by Neonectria ditissima 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.
