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...
متن کاملVegetative 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...
متن کاملVerticillium dahliae toxins-induced nitric oxide production in Arabidopsis is major dependent on nitrate reductase.
The source of nitric oxide (NO) in plants is unclear and it has been reported NO can be produced by nitric oxide synthase (NOS) like enzymes and by nitrate reductase (NR). Here we used wild-type, Atnos1 mutant and nia1, nia2 NR-deficient mutant plants of Arabidopsis thaliana to investigate the potential source of NO production in response to Verticillium dahliae toxins (VD-toxins). The results ...
متن کاملEvaluation of strawberry cultivars for resistance to Verticillium dahliae Kleb
Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...
