Detection of Molecular Markers Linked To Bread Wheat Take-All Disease (Gaeumannomyces Graminis Var. Tritici) T-41 Isolation
Take-all is one of the most important diseases of wheat in wet areas, causing significant damage in these areas, and there has not introduced any resistant varieties against this disease until now. Therefore, efforts to identify the resistance genes to this disease and developing resistant varieties or cultivars with lower susceptible in bread wheat have a great importance.In this research...
متن کاملCloning, characterization, and transcription of three laccase genes from Gaeumannomyces graminis var. tritici, the take-all fungus.
Gaeumannomyces graminis var. tritici, a filamentous ascomycete, is an important root pathogen of cereals that causes take-all disease and results in severe crop losses worldwide. Previously we identified a polyphenol oxidase (laccase) secreted by the fungus when induced with copper. Here we report cloning and partial characterization of three laccase genes (LAC1, LAC2, and LAC3) from G. gramini...
متن کاملThe biocontrol bacterium Pseudomonas fluorescens Pf29Arp strain affects the pathogenesis-related gene expression of the take-all fungus Gaeumannomyces graminis var. tritici on wheat roots
The main effects of antagonistic rhizobacteria on plant pathogenic fungi are antibiosis, fungistasis or an indirect constraint through the induction of a plant defence response. To explore different biocontrol mechanisms, an in vitro confrontation assay was conducted with the rhizobacterium Pseudomonas fluorescens Pf29Arp as a biocontrol agent of the fungus Gaeumannomyces graminis var. tritici ...
متن کاملDetoxification of Benzoxazolinone Allelochemicals from Wheat by Gaeumannomyces graminis var. tritici, G. graminis var. graminis, G. graminis var. avenae, and Fusarium culmorum.
The ability of phytopathogenic fungi to overcome the chemical defense barriers of their host plants is of great importance for fungal pathogenicity. We studied the role of cyclic hydroxamic acids and their related benzoxazolinones in plant interactions with pathogenic fungi. We identified species-dependent differences in the abilities of Gaeumannomyces graminis var. tritici, Gaeumannomyces gram...
متن کاملColonization of barley roots by endophytic fungi and their reduction of take-all caused by Gaeumannomyces graminis var. tritici.
Fungal root endophytes obtained from natural vegetation were tested for antifungal activity in dual culture tests against the root pathogen Gaeumannomyces graminis var. tritici. Fifteen isolates, including Acremonium blochii, Acremonium furcatum, Aspergillus fumigatus, Cylindrocarpon sp., Cylindrocarpon destructans, Dactylaria sp., Fusarium equiseti, Phoma herbarum, Phoma leveillei, and a steri...
