Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

Comparing methods to determine European canker resistance in apple tree accessions
Pruning cuts made in summer and pruning cuts leaf scars and score wounds made in autumn were inoculated to compare their suitability to discriminate for European canker resistance among apple accessions When pruning cuts were inoculated in summer the mean lesion size varied between accessions with Royal Gala displaying significantly larger lesions than

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

An endopolygalacturonase gene of Diaporthe helianthi
In an attempt to define virulence determinants of Diaporthe helianthi, the causative agent of sunflower stem canker, the gene named Dhpg, coding for an endopolygalacturonase, was investigated in the highly virulent strain 8/96 isolated from a diseased ...

This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor

The effect of nitrogen source on in vitro growth of Neonectria ditissima (European canker)
Nitrogen fertilisers are widely used in apple orchards. However, the effects of various nitrogen sources on growth and sporulation of the fungus Neonectria ditissima, which causes European canker, are not fully understood. The effects of various nitrogen sources commonly used in apple orchards (potassium nitrate, ammonium chloride, ammonium nitrate ...

The Rise of Stemphylium vesicarium: A Growing Threat to Pear Production in Europe
Brown spot of pear, caused by the fungus Stemphylium vesicarium, was reported in Italy in 1975 and only recently, due to climate change and pesticide restrictions, it became a major threat for European pear production. New knowledge on this pathogen can allow the advent of new and effective control strategies.

Protection of budding wounds in apple nursery trees from European canker
The fungus Neonectria ditissima can cause European canker in apple nursery trees In this study ten treatments of EMLA 9 rootstocks budded with Royal Gala were examined 5 Treatments included combinations of five budding tapes two budding methods and three fungicidal treatments Fifteen months after inoculation all Tbudded trees had died Chipbudded trees ...
