Peptide synthetase gene in Trichoderma virens.
Trichoderma virens (synonym, Gliocladium virens), a deuteromycete fungus, suppresses soilborne plant diseases caused by a number of fungi and is used as a biocontrol agent. Several traits that may contribute to the antagonistic interactions of T. virens with disease-causing fungi involve the production of peptide metabolites (e.g., the antibiotic gliotoxin and siderophores used for iron acquisi...
متن کاملEnhanced fungal resistance in transgenic cotton expressing an endochitinase gene from Trichoderma virens.
Mycoparasitic fungi are proving to be rich sources of antifungal genes that can be utilized to genetically engineer important crops for resistance against fungal pathogens. We have transformed cotton and tobacco plants with a cDNA clone encoding a 42 kDa endochitinase from the mycoparasitic fungus, Trichoderma virens. Plants from 82 independently transformed callus lines of cotton were regenera...
متن کاملGenetic 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 کاملAdenovirus homologous recombination does not require expression of the immediate-early E1a gene.
To investigate whether early genes other than those involved directly in DNA replication are required for efficient adenovirus recombination, pairs of viruses with deletions in E1a, E1b 496R, E1b 196R, or E4 and containing differing restriction site markers were used to infect both permissive and non- or semipermissive cells. Recombination was assayed among intracellular and extracellular genom...
متن کاملA Novel Cellulase Produced by a Newly Isolated Trichoderma virens
Screening and obtaining a novel high activity cellulase and its producing microbe strain is the most important and essential way to improve the utilization of crop straw. In this paper, we devoted our efforts to isolating a novel microbe strain which could produce high activity cellulase. A novel strain Trichoderma virens ZY-01 was isolated from a cropland where straw is rich and decomposed, by...
