Sclerotinia stem rot (SSR) is one of the most destructive disease mustard which affects quality and quantity crop resulting in severe yield losses. The present study was conducted to evaluate bio-efficacy different Trichoderma spp. plant extracts against sclerotiorum under laboratory conditions. All tested showed a significant effect on growth inhibition test fungus over control. Among spp., ma...

Biofouling is a widespread phenomenon in oceans worldwide. With increasing human development and activities open coastal waters, due to the environmental impact of AF organotins copper-based paint, demand for nontoxic antifouling (AF) paints increasing. Various bioassays antimicrobial activity, anti-biofilm formation anti-barnacle settlement were established evaluate possibility using marine na...

We surveyed the Trichoderma (Hypocreales, Ascomycota) biodiversity in agricultural fields in four major agricultural provinces of East China. Trichoderma strains were identified based on molecular approaches and morphological characteristics. In three sampled seasons (spring, summer and autumn), 2078 strains were isolated and identified to 17 known species: T. harzianum (429 isolates), T. asper...

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...

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screeni...

Towards assessing the biodiversity and biogeography of Trichoderma, we have analyzed the occurrence of Trichoderma species in soil and litter from four areas in China: North (Hebei province), South-East (Zhejiang province), West (Himalayan, Tibet) and South-West (Yunnan province). One hundred and thirty five isolates were grouped according to tentative morphological identification. A representa...

We examined the mycoparasitic and saprotrophic behavior of isolates representing groups of Trichoderma harzianum to establish a mechanism for the aggressiveness towards Agaricus bisporus in infested commercial compost. Mycoparasitic structures were infrequently observed in interaction zones on various media, including compost, with cryoscanning electron microscopy. T. harzianum grows prolifical...

Evidence for the role of chitinases in biocontrol by Trichoderma species has been well documented.Chit42 lacks a chitin–binding domain (ChBD) which is involved in its binding activity to insoluble chitin. The objective of the present study was to enhance antifungal activity of T. harzianum by overexpression of wild type and hybrid forms of Chit42 containing chitin binding domain. To produce chi...
