با توجه به قابلیت بالای قارچ تریکودرما در کنترل بیولوژیک بسیاری از عوامل بیماریزا، جداسازی و شناسایی گونههای تریکودرمای خزانههای توتون استان مازندران انجام شد. جداسازی قارچها با استفاده از محیط کشت انتخابی داوه و محیط های عمومی CMA , PDA ,WA به روش کشت سوسپانسیون خاک انجام شد. بعد از خالص سازی نمونههای جدا شده، با استفاده از ویژگیهای ماکرومورفولوژیکی و میکرومورفولوژیکی اندامهایی از قبیل ک...
The aim of the present study was to examine the abilities of twenty-four isolates belonging to ten different Trichoderma species (i.e., Trichoderma atroviride, Trichoderma citrinoviride, Trichoderma cremeum, Trichoderma hamatum, Trichoderma harzianum, Trichoderma koningiopsis, Trichoderma longibrachiatum, Trichoderma longipile, Trichoderma viride and Trichoderma viridescens) to inhibit the myce...
Potato ranks fourth as the most important food crop in the world. The crop is known to suffer from many diseases among which late blight is more devastating. Therefore, culture filtrates of bio-control agents, (Trichoderma virens, Trichoderma viride, Paecilomyces lilacinus and Pseudomonas fluorescens) were tested for their effectiveness on the spore germination and infection in-vitro, as fungic...
Five bacteria (Pseudomonas fluorescens, P. fluorescens subgroup G strain 2, P. marginalis, P. putida subgroup B strain 1 and P. syringae strain 1) and three fungi (Penicillium brevicompactum, P. solitum strain 1 and Trichoderma atroviride) were evaluated to determine their promoting effect on the growth of mature healthy tomato plants grown under hydroponic conditions. P. putida and T. atroviri...
A laboratory and green house experiment was carried out on the comparative antagonistic performance of four different bioagents (Aspergillus sp., Gliocladium virens, Trichoderma harzianum and T. viride) isolated from soil against Rhizoctonia solani. Under laboratory conditions, T. harzianum exhibited maximum (75.55%) mycelial growth inhibition of R. solani This was followed by T. viride, which ...
بیماری بلاست (blast) با عامل magnaporthe oryzae مهمترین بیماری برنج در جهان میباشد. استفاده از سموم شیمیایی اگر چه باعث کنترل بیماری میگردند، اما آسیبهای جدی متوجه انسان و محیط زیست میکنند. امروزه کنترل بیولوژیک بیماریهای گیاهی به عنوان یک روش جایگزین و بیخطر، مورد توجه و تأکید ویژهای قرار گرفته است. در این تحقیق، نمونه برداری از خاک شالیزار و اندامهای هوایی برنج در مناطق مختلف استان م...
Sugar beet cyst forming nematode (Heterodera schachtii) is one of the most important pathogens of the sugar beet in Iran. For biological control of Heterodera schachtii, 10 isolates of Trichoderma related to two species T. harzianum and T. virens were examined in laboratory and green house on eggs and cysts for two years. Results obtained from the laboratory assay showed that isolates of Tricho...
The lignocellulosic enzymes of Trichoderma asperellum have been intensely investigated toward efficient conversion biomass into high-value chemicals/industrial products. However, lack genome data is a remarkable hurdle for hydrolase systems studies. secretory newly isolated T. ND-1 during lignocellulose degradation are currently poorly known. Herein, high-quality genomic sequence ND-1, obtained...
The recently identified phylogenetic subgroup B5 of fungal glycoside hydrolase family 18 genes encodes enzymes with mannosyl glycoprotein endo-N-acetyl-β-D-glucosaminidase (ENGase)-type activity. Intracellular ENGase activity is associated with the endoplasmic reticulum associated protein degradation pathway (ERAD) of misfolded glycoproteins, although the biological relevance in filamentous fun...
