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 کاملIdentification of peptaibols from Trichoderma virens and cloning of a peptaibol synthetase.
The fungus Trichoderma virens is a ubiquitous soil saprophyte that has been applied as a biological control agent to protect plants from fungal pathogens. One mechanism of biocontrol is mycoparasitism, and T. virens produces antifungal compounds to assist in killing its fungal targets. Peptide synthetases produce a wide variety of peptide secondary metabolites in bacteria and fungi. Many of the...
متن کاملIsolation and characterisation of a partial peptide synthetase gene from Trichoderma asperellum.
Many species of Trichoderma have attracted interest as agents for the biological control of soil borne fungal pathogens of a range of crop plants. Research on the biochemical mechanisms associated with this application has focused on the ability of these fungi to produce enzymes which lyse fungal cell walls, and antifungal antibiotics. An important group of the latter are the non-ribosomal pept...
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 کاملFunctional analysis of tvsp1, a serine protease-encoding gene in the biocontrol agent Trichoderma virens.
Serine proteases are highly conserved among fungi and considered to play a key role in different aspects of fungal biology. These proteases can be involved in development and have been related to pathogenesis or biocontrol processes. A gene (tvsp1) encoding an extracellular serine protease was cloned from Trichoderma virens, a biocontrol agent effective against soilborne fungal pathogens. The g...
