Fungal species belonging to the genus Trichoderma are worldwide in occurrence and easily isolated from soil, decaying wood, and other forms of plant organic matter. They are, for the most part, classified as imperfect fungi, in that they have no known sexual stage. Rapid growth rate in culture and the production of numerous spores (conidia) that are varying shades of green characterize fungi in...
Water contamination with large amounts of industrial textile coloured effluents is an environmental concern. For the treatment of textile effluents, white-rot fungi have received extensive attention due to their powerful capability to produce oxidative (e.g., ligninolytic) enzymes. In addition, other groups of fungi, such as species of Aspergillus and Trichoderma, have also been used for textil...
Colonisation of plant roots by selected beneficial Trichoderma fungi or Pseudomonas bacteria can result in the activation of a systemic defence response that is effective against a broad spectrum of pathogens. In Arabidopsis thaliana, induced systemic resistance (ISR) triggered by the rhizobacterial strain Pseudomonas fluorescens WCS417r is regulated by a jasmonic acid- and ethylene-dependent d...
Mycoparasitic strains of Trichoderma are applied as commercial biofungicides for control of soilborne plant pathogens. Although the majority of commercial biofungicides are Trichoderma based, chemical pesticides, which are ecological and environmental hazards, still dominate the market. This is because biofungicides are not as effective or consistent as chemical fungicides. Efforts to improve t...
جنس cyperus (cyperaceae) و datura (solanaceae) دارای خواص دارویی بوده و دارای اثر آنتی اکسیدانی، ضد التهابی، ضد میکروبی و ضد سرطانی می باشند. c.longusیک گونه از جنس cyperus و بومی ایران می باشد که تاکنون تحقیقی بر روی آن صورت نگرفته است، ¬¬¬¬d.stramonium هم یک گونه از جنس datura و بومی ایران می باشد که تحقیقات چندانی بر روی گونه بومی مازندران آن صورت نگرفته است. در این بررسی فعالیت آنتی باک...
The antagonistic effect of Trichoderma harzianum on a range of seed-borne fungal pathogens of wheat (viz. Fusarium graminearum, Bipolaris sorokiniana, Aspergillus spp., and Penicillium spp.) was assessed. The potential of T. harzianum as a biocontrol agent was tested in vitro and under field conditions. Coculture of the pathogens and Trichoderma under laboratory conditions clearly showed domina...
Plants are constantly exposed to microbes, for this reason they have evolved sophisticated strategies to perceive and identify biotic interactions. Thus, plants have large collections of so-called resistance (R) proteins that recognize specific microbe factors as signals of invasion. One of these proteins is codified by the Arabidopsis thaliana HR4 gene in the Col-0 ecotype that is homologous t...
Fungi Trichoderma spp. are present in nearly all soils and other habitats. Most of Trichoderma strains are efficient for control of some pathogens. Some strains induce plant native defence mechanisms. Botrytis cinerea [Pers.: Fr.] causes economic losses on a wide range of cultivated plants and stored fruits. In presented work Trichoderma asperellum [strain T1] isolated from commercial product w...
Certain species of the fungal genus Trichoderma are potent mycoparasites and are used for biological control of fungal diseases on agricultural crops. In Trichoderma, whole-genome sequencing reveal between 20 and 36 different genes encoding chitinases, hydrolytic enzymes that are involved in the mycoparasitic attack. Sequences of Trichoderma chitinase genes chi18-5, chi18-13, chi18-15 and chi18...
Trichoderma asperellum and cucumber seedlings were used as a model to study the modulation of Trichoderma gene expression during plant root colonization. Seedlings were grown in an aseptic hydroponics medium and inoculated with Trichoderma spore suspension. Proteins differentially secreted into the medium were isolated. Three major proteins of fungal origin were identified: two arabinofuranosid...
