Trichoderma brevicompactum IBT 40841 produces trichodermin, a trichothecene-type toxin that shares most of the steps of its biosynthesis with harzianum A, another trichothecene produced by several Trichoderma species. The first specific step in the trichothecene biosynthesis is carried out by a terpene cylcase, trichodiene synthase, that catalyzes the conversion of farnesyl pyrophosphate to tri...

Algunas especies del género Trichoderma poseen la capacidad de parasitar patógenos fúngicos plantas. Esto las hace interesantes en el control enfermedades (antracnosis) causadas por hongos fruto aguacate poscosecha. Por lo tanto, objetivo esta investigación fue aislamiento e identificación cepas nativas spp. cultivos con potencial antagonista in vivo vitro contra este fruto. Las fueron aisladas...

Trichoderma is a genus of filamentous fungi with highly beneficial species for use in agriculture due to its ability combat disease, increase growth, tolerance abiotic stresses and resistance biotic plants. To do this, must effectively colonize the roots plant, being able overcome existing plant defenses. In this sense, glucosinolates (GSLs) are group secondary metabolites present cruciferous d...

Trichoderma spp. are known as a rich source of secondary metabolites with biological activity belonging to a variety of classes of chemical compounds. These fungi also are well known for their ability to produce a wide range of antibiotic substances and to parasitize other fungi. In search for new substances, which might act as anticancer agents, the overall objective of this study was to inves...

Trichoderma is an opportunistic, avirulent plant symbiont. Chitin is the main structural component of fungi, enzyme responsible to metabolize the chitin and various techniques to enhance the chitinolytic enzyme production at the genetic level are receiving great attention to develop the efficient biocontrol agent. UV mutagenesis was found to be one of the novel strategy for developing Trichoder...

blight, caused by mycosphaerella rabiei is the most important disease of chickpea in iran. in order to find a method for the biological control of the disease, the inhibitory effect of 36 isolates of three species, trichoderma harzianum, t. virens and t. atroviride, on a most virulent isolate of the pathogen, in hyperparasitism, dual culture, and production of volatile antibiotic compounds were...

Objective: The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Methods: Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promotin...

Disease resistance in transgenic plants has been improved, for the first time, by the insertion of a gene from a biocontrol fungus. The gene encoding a strongly antifungal endochitinase from the mycoparasitic fungus Trichoderma harzianum was transferred to tobacco and potato. High expression levels of the fungal gene were obtained in different plant tissues, which had no visible effect on plant...
