In Ascomycota the protein methyltransferase LaeA is a global regulator that affects the expression of secondary metabolite gene clusters, and controls sexual and asexual development. The common mycoparasitic fungus Trichoderma atroviride is one of the most widely studied agents of biological control of plant-pathogenic fungi that also serves as a model for the research on regulation of asexual ...

In this study, effects of single and combined applications biocontrol agents; Trichoderma spp. (T. atroviride, T. virens) plant growth promoting rhizobacteria (Pseudomonas koreensis, Bacillus subtilis) on growth, wilt disease severity caused by Verticillium dahliae defence-related enzymes (peroxidase, polyphenol oxidase, phenylalanine ammonium lyase β-1,3 glucanase) eggplant, were investigated....

The genus Trichoderma is one of the most widely used biological control agents of plant-pathogenic fungi. The main mechanism for survival and dispersal of Trichoderma is through the production of asexual spores (conidia). The transition from filamentous growth to conidiation can be triggered by light, nutrient deprivation, and mechanical damage of the mycelium. We conducted proteomic profiling ...

Mycoparasitic Trichoderma species are applied as biocontrol agents in agriculture to guard plants against fungal diseases. During mycoparasitism, Trichoderma directly interacts with phytopathogenic fungi, preceded by a specific recognition of the host and resulting in its disarming and killing. In various fungal pathogens, including mycoparasites, signalling via heterotrimeric G proteins plays ...

Rhizosphere-competent fungi of the genus Trichoderma are widely used as biofertilizers and biopesticides in commercial formulates because of the multiple beneficial effects on plant growth and disease resistance. In this work, we demonstrate that genetic variability among wild and cultivated tomato lines affects the outcome of the interaction with two 'elite' biocontrol strains of T. atroviride...

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...

Biocontrol agents generally do not perform well enough under field conditions to compete with chemical fungicides. We determined whether transgenic strain SJ3-4 of Trichoderma atroviride, which expresses the Aspergillus niger glucose oxidase-encoding gene, goxA, under a homologous chitinase (nag1) promoter had increased capabilities as a fungal biocontrol agent. The transgenic strain differed o...

Background The ascomycete fungus Trichoderma reesei is the predominant source of enzymes for industrial conversion of lignocellulose. Its glycoside hydrolase family 7 cellobiohydrolase (GH7 CBH) TreCel7A constitutes nearly half of the enzyme cocktail by weight and is the major workhorse in the cellulose hydrolysis process. The orthologs from Trichoderma atroviride (TatCel7A) and Trichoderma har...

Medicinal plants may become a favourable habitat for associative microorganisms, especially endophytic microbes inhabiting Zingiberaceaen species. Preliminary investigation has revealed an assemblage of fungi colonizing the healthy rhizome Elettaria sp. collected from Sibayak Forest, North Sumatra based on molecular evidences. This study investigated IAA-producing and antifungal activity Elleta...
