Trichoderonic acids A (1) and B (2), novel terpenoids, and (+)-heptelidic acid (3) isolated from cultures of a fungus, Trichoderma virens, and their structures were identified by spectroscopic analysis. These compounds selectively and competitively inhibited the activities of mammalian DNA polymerases beta, lambda (pols beta, lambda), and terminal deoxynucleotidyl transferase (TdT) in family X ...

Six strain of Trichoderma (T. viride, T. harzianum, T. reesei, T. longibrachiatum, T. koningii, T. virens) were isolated and used for extracellular enzyme production. Species of Trichoderma are collected from the surrounding soil of suger beet root fields in East Iran, and held in vitro cultured PDA. TCM and TFM are used for the growth of spores and induceing the production of Cellulase. Finall...

the aim of present study was to investigate the effect of individual and co-inoculation of trichoderma species and arbuscular mycorrhizal fungi (amf) on growth, mycorrhization, population of trichoderma, and wilt disease severity in pigeon pea (cajanus cajan l millsp). three species of trichoderma, namely, t. harzianum (th), t. virens (tr), and t. viride (tv) and consortium of amf (myc; mixture...

Mutualistic fungal endophytes infect many grass species and often confer benefits to the hosts such as reduced herbivory by insects and animals. The physiological interactions between the endophytes and their hosts have not been well characterized. Fungal-secreted proteins are likely to be important components of the interaction. In the interaction between Poa ampla and the endophyte Neotyphodi...

The gene lamAI, which encodes a novel laminarinase AI of Trichoderma viride U-1, was cloned using RT-PCR in conjunction with the rapid amplification of cDNA ends (RACE) technique. The open reading frame consisted of 2,277 bp encoding a protein of 759 amino acid residues, including a 32-residue signal prepropeptide. The protein showed 91% sequence similarity to the putative Trichoderma virens be...

Bu çalışmada, nane yetiştiriciliğinde önemli hastalıklara sebep olan fungal patojenlerden Fusarium oxysporum ve Rhizoctonia solani' ye karşı Trichoderma harzianum virens biyolojik kontrol etmenlerinin etkisi araştırılmıştır. aşamada solgunluk belirtisi gösteren bitkilerinin köklerinden yapılan izolasyonlar sonucunda F. R. solani izolatları elde edilmiş tanıları yapılmıştır. In vivo’da T. biyoet...
