Venturia asperata (Ascomycetes) was first described in 1975, as a saprotroph on overwintered apple leaf litter, and then, in 2007, as the cause of atypical apple scab symptoms on scab-resistant apple cultivars in southern France, and later in northern ...

The Vf locus, originating from the crabapple species Malus floribunda 821, confers resistance to five races of the fungal pathogen Venturia inaequalis, the causal agent of apple scab disease. Previously, a cluster of four receptor-like genes, Vfa1, Vfa2,

Use of genetic resources and partial resistances for apple breeding [PDF]
Modern apple breeding strategies are mainly considering the most advanced selections and culti-vars as parents. This tends to lead to a narrowed genetic basis.

ABSTRACT Downy mildew (Plasmopara), apple scab (Venturia inaequalis), and Alternaria leaf blight are endemic diseases that affect crops worldwide. The diseases can cause severe losses in grapes, apples and carrots when not detected and treated in an early stage.

The fungal effectors Zt‐KP4‐1 and Zt‐KP6‐1 of Zymoseptoria tritici are structural homologues of killer toxins KP4 and KP6α of Ustilago maydis, are antifungal, and their structural homologues are widespread in fungi. ABSTRACT Fungal effectors play crucial roles in plant infection. Despite low sequence identity, they were recently discovered to belong to

Micro area based spatial distribution of apple scab in an organic apple orchard
In this study, the objective was to report a two-year investigation on micro area based spatial distribution of apple scab in an organic apple orchard. Results showed that number of symptomatic plant part ranged between 587 and 623 on leaf and between 46

Field efficacy of new compounds to replace copper for scab control in organic apple production [PDF]
Efficacy of compounds was investigated in field experiments in Denmark and the Netherlands according to EPPO guidelines. Some Yucca extracts and potassium bicarbonate had an efficacy similar to sulphur on leaves.

ABSTRACT Background Until 2020, azole resistance in Aspergillus fumigatus complex isolates in New Zealand was due to cyp51A hot spot mutations. This report details the appearance of environment‐linked tandem repeat (TR)‐related azole resistance genotypes since 2021. Methods Isolates were tested by broth micro‐dilution.

Prospecting for organic fungicides and resistance inducers to control scab (Venturia inaequalis) in organic apple production [PDF]
As a part of the REPCO project we are prospecting for plant extracts and other materials to control apple scab in order to find substitutes for copper fungicides in organic apple production.

Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase
The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...
