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 کاملAcquisition of Resistance to Sterol Demethylation Inhibitors by Populations of Venturia inaequalis.
ABSTRACT Acquisition of resistance to sterol demethylation inhibitors (DMIs) by populations of Venturia inaequalis was investigated using a microscopical method developed by C. Siebels and K. Mendgen. Microscopical analysis of conidiophore formation enabled the earlier detection of resistance and a clearer distinction between DMI-resistant and DMI-sensitive populations than other in vivo method...
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 کاملResistance to Myclobutanil in Populations of Venturia inaequalis in Winchester, Virginia
Sterol-inhibiting (SI) fungicides are widely used to manage apple scab, caused by Venturia inaequalis. However, recent observations indicate that populations of V. inaequalis in orchards in Virginia have developed resistance to myclobutanil and other SI fungicides. Little is known about the frequency and distribution of fungicide resistance in apple scab populations in Virginia. Isolates of V. ...
متن کاملPurification and partial characterization of an extracellular melanoprotein from the fungus Venturia inaequalis.
The fungus Venturia inaequalis clone No. 36 isolated from Malus domestica cv. Gloster excretes a melanoprotein of 36 kDa in relatively high amounts during growth in liquid culture. The protein was isolated from the culture medium and purified to homogeneity. It was shown to contain melanin. After raising an antiserum against the isolated protein, the protein could be shown to be located in the ...
