Peptaibols are linear alpha-aminoisobutyric acid-containing peptide antibiotics originating from soil fungi mainly of the genus Trichoderma and biosynthesized in complex mixtures of closely related analogues by a polyenzymatic pathway. Addition of amino acids such as alpha-aminoisobutyric acid (Aib), glutamic acid or arginine, to the fermentation medium of two Trichoderma strains, T. harzianum ...

strains of trichoderma harzianum s. l. have a great importance because of affecting mankind by being used as biological control agents against plant pathogens. in the present study, we planned to characterize the phylogenetic structure of t. harzianum recovered from different geographical origins and various habitats in some climates of iran (nc, scd, csw). in order to screen 239 collected tric...

Trichoderma species are commercially applied as biocontrol agents against numerous plant pathogenic fungi due to their production of antifungal metabolites, competition for nutrients and space, and mycoparasitism. However, currently the identification of Trichoderma species from throughout the world based on micro-morphological descriptions is tedious and prone to error. The correct identificat...

Trichothecenes are fungal sesquiterpenoid compounds, the majority of which have phytotoxic activity. They contaminate food and feed stocks, resulting in potential harm to animals and human beings. Trichoderma brevicompactum and T. arundinaceum produce trichodermin and harzianum A (HA), respectively, two trichothecenes that show different bioactive properties. Both compounds have remarkable anti...

Maize is a cereal crop essential to fulfill the need for food and support global security programs. hybrid varieties play very significant role in increasing maize production. Objectives of research were obtain tester, which consistent identifying inbred lines with high specific combining ability, prospective crossed-hybrids that have potential assembling be varieties. The grain yield showed ab...

Studies were undertaken to determine the comparative efficacy of native biocontrol agents viz., Pseudomonas fluorescens isolate PS-4, Trichoderma harzianum isolate TH-H-3 and T. virens isolate TV-K-3 @ 5X10 cfu/g talc; organic amendments viz., neem seed powder @ 250 mg/kg soil and farmyard manure @ 8 1500 mg/kg soil; carbofuran @ 33.4 mg/kg soil, topsin-M @ 1.4 mg/kg soil and bavistin @ 2.0 mg/...

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

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...

The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...
