Fungi belonging to the genus Trichoderma, commonly found in soil or colonizing plant roots, exert beneficial effects on plants, including the promotion of growth and the induction of resistance to disease. T. virens and T. atroviride secrete the proteins Sm1 and Epl1, respectively, which elicit local and systemic disease resistance in plants. In this work, we show that these fungi promote growt...

Fungi of the genus Trichoderma are used as biocontrol agents against several plant pathogenic fungi like Rhizoctonia spp., Pythium spp., Botrytis cinerea and Fusarium spp. which cause both soil-borne and leaf- or flower-borne diseases of agricultural plants. Plant disease control by Trichoderma is based on complex interactions between Trichoderma, the plant pathogen and the plant. Until now, tw...

samples were collected from soil and as well from phyllosphere of rice plant and subjected to dilution plate technique on rbsf trichoderma selective medium. a total of 202 trichoderma isolates were obtained from rice fields at different geographical locations distributed all over mazandaran province. single spore isolates were obtained and genomic dna extracted from all the isolates using dna e...

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...

the effect of different isolates of trichoderma namely t. virens t65, t virens t90, t. virens t96, t. virens t122, t. brevicompactum t146, t. koningiopsis t149, t. viridecense t150, t. koningii as well as two trichodermin b and subtilin commercial bioproducts on growth promotion in wheat were studied through seed coating method in a compeletly randomized design in a glasshouse experiment. the i...

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...
