Genetic Transformation of the Biocontrol Fungus Gliocladium virens to Benomyl Resistance.
Methodology was developed to isolate and regenerate protoplasts from the biocontrol fungus Gliocladium virens and to transform them to benomyl resistance with a Neurospora crassa beta-tubulin gene. Southern blots demonstrated that multiple copies of the vector integrated into the chromosomal DNA of stable biotypes but not of abortive transformants. Analysis of nuclear condition in vegetative an...
متن کاملProduction of Extracellular Proteins by the Biocontrol Fungus Gliocladium virens.
Gliocladium virens is a common saprophytic fungus that is mycoparasitic on a large number of fungi. Responses of G. virens toward its environment were examined by monitoring the presence of extracellular proteins in culture fluid during time course experiments. Culture fluid of G. virens grown on glucose, washed cell walls of Rhizoctonia solani (one of its hosts), olive oil, or chitin contained...
متن کاملThe structure of gliovirin, a new antibiotic from Gliocladium virens.
In an earlier study, we reported the presence of the antibiotic, heptelidic acid, in the fungus, Gliocladium virens1). From this same organism we have isolated two additional compounds, one of which is selectively active against members of the Oomycetes2). We call this compound gliovirin (1). The second compound, L,L-phenylalanine anhydride (9), may be the biosynthetic precursor to gliovirin. G...
متن کاملAntitubercular activity of the fungus Gliocladium sp. MR41 strain
Tuberculosis (TB) is leading cause of death worldwide from infectious diseases and its inadequate treatment has led to emergence of resistant strains. The emergence of these strains renders the search for new drugs for the treatment of TB. The aim of this study was the evaluation of the anti-TB activity of the extract from fungus Gliocladium sp. MR41, and bioassay-guided fractionation and ident...
متن کاملSm1, a proteinaceous elicitor secreted by the biocontrol fungus Trichoderma virens induces plant defense responses and systemic resistance.
The soilborne filamentous fungus Trichoderma virens is a biocontrol agent with a well-known ability to produce antibiotics, parasitize pathogenic fungi, and induce systemic resistance in plants. Even though a plant-mediated response has been confirmed as a component of bioprotection by Trichoderma spp., the molecular mechanisms involved remain largely unknown. Here, we report the identification...
