Variability of the Pathogenicity of Venturia inaequalis in Europe
In the frame of the DARE (Durable Apple Resistance in Europe) project, a collection of strains of Venturia inaequalis was established. It comprises 319 strains from 8 European countries, isolated from 48 different Malus species and M. x domestica cultivars. The pathogenicity of 39 strains from this collection was tested on a set of 8 differential hosts, under controlled conditions (in a growth-...
متن کاملMonitoring of Venturia inaequalis harbouring the QoI resistance G143A mutation in French orchards as revealed by PCR assays.
BACKGROUND Genetic resistance to QoI fungicides may account for recent failures to control Venturia inaequalis (Cooke) Winter in French orchards. Two PCR-based assays were developed to detect the G143A point mutation in the fungal mitochondrial cytochrome b gene. The mutation is known to confer a high level of resistance to QoI fungicides. Occurrence of the G143A mutation in French field isolat...
متن کاملA Large Family of AvrLm6-like Genes in the Apple and Pear Scab Pathogens, Venturia inaequalis and Venturia pirina
Venturia inaequalis and V. pirina are Dothideomycete fungi that cause apple scab and pear scab disease, respectively. Whole genome sequencing of V. inaequalis and V. pirina isolates has revealed predicted proteins with sequence similarity to AvrLm6, a Leptosphaeria maculans effector that triggers a resistance response in Brassica napus and B. juncea carrying the resistance gene, Rlm6. AvrLm6-li...
متن کاملDetection of Biotic Stress (venturia Inaequalis) in Apple Trees Using Hyperspectral Analysis
The potential yield of (capital)-intensive multi-annual crops (e.g., fruit) is seldom harvested in reality. A targeted monitoring and modelling of the growth processes in such agricultural production systems could enable an early detection and treatment of production limiting factors, thereby optimising yield. In Belgium, as in all temperate regions, scab stress caused by the ascomycete Venturi...
