Phylogenetic Analysis of Verticillium dahliae Vegetative Compatibility Groups

Vegetative compatibility groups partition variation in the virulence of Verticillium dahliae on strawberry

Verticillium dahliae infection of strawberry (Fragaria x ananassa) is a major cause of disease-induced wilting in soil-grown strawberries across the world. To understand what components of the pathogen are affecting disease expression, the presence of the known effector VdAve1 was screened in a sample of Verticillium dahliae isolates. Isolates from strawberry were found to contain VdAve1 and we...

An efficient method for selecting stable tester strains of vegetative compatibility groups in Verticillium dahliae

The way compatible pairs of nitrate non-utilizing mutants (nit) are selected is usually not explained and remains unclear whether these pairs are representative for an isolate or strain. In addition, tester strains of Verticillium dahliae vegetative compatibility groups (VCGs) cross-react with at least one pair of tester strains of another VCG, and although it is a common knowledge of scientist...

Vegetative compatibility, host range and pathogenicity of Verticillium dahliae isolates in Iran

Verticillium wilt is an economically important disease which inflicts serious losses in potato, cotton, alfalfa, some vegetable crops and fruit trees and occasionally ornamentals. Verticillium dahliae, infected cultivated species and weeds were collected from several areas in Iran during tewelve years from 1993-2005 and studied for their vegetative compatibility, host range and pathogenecity. T...

Resistance and vegetative growth analysis of some olive cultivars in response to a defoliating pathotype of Verticillium dahliae Kleb

Verticillium dahliae Kleb. the causal agent of vascular wilt is an important pathogen of olive trees in growing areas of the world. Nine-month-old nursery olives including ‘Bladi’, ‘Conservalia’, ‘Kalamon’, ‘Koroneiki’, ‘Manzanilla’, ‘Mission’, ‘Marry’, ‘Picual’, ‘Rowghani’, ‘Sevillana’ and ‘Zard’ cultivars were root-dip inoculated with a defoliating (VCG1) isolate of V. dahliae obtained from d...
