Si ngh A, Islam MN (2010) In vitro evaluation of Trichoderma spp against Phytophthora nicotianae. Int. J. Expt. Agric. 1(1), 20-25. The Blank sank disease of tobacco caused by Phytophthora nicotianae results in considerable loss of the crop. This lab study aimed to investigate antagonistic activity of Trichoderma spp isolates against P. nicotianae. Three isolates of Trichoderma harzianum and on...

background: acanthamoeba spp. is the causative agent of blindness keratitis and fatal encephalaitis. presence of acanthamoeba spp. in a wide variety of niches such as different water types can lead to exposure of high risk people such as contact lens wearers. the main aim of the present study was to explore the occurrence of acanthamoeba genotypes in the recreational water sources using both mo...

Multiple lineage-specific surface molecules have recently been defined on human T lymphocytes. Although some of these appear during late intrathymic ontogeny and are maintained on all peripheral T cells (T3), others (T4, TS) arise earlier in differentiation and are selectively expressed on functional subpopulations of human T lymphocytes (1-3). In the case of the 20,000-mol wt T3 surface molecu...

This work was presented in part at the 53rd Annual Meeting of The American Thyroid Association, Cleveland, Ohio, 7-10 September 1977. Dr. Larsen is an Investigator of the Howard Hughes Medical Institute. Received for publication 29 August 1977 and in revised form 11 January 1978. well with both the change in TSH and the nuclear occupancy, suggesting a linear relationship between the integrated ...

blight, caused by mycosphaerella rabiei is the most important disease of chickpea in iran. in order to find a method for the biological control of the disease, the inhibitory effect of 36 isolates of three species, trichoderma harzianum, t. virens and t. atroviride, on a most virulent isolate of the pathogen, in hyperparasitism, dual culture, and production of volatile antibiotic compounds were...

to identify trichoderma isolates for potential biocontrol of crown and root rot inpistachio, 100 samples of soil taken from rhizosphere, fertilizer channels and from soil surfacewere collected from kerman, yazd, khorasane razavi and semnan provinces during 2009-2011. overall, 32 isolates of trichoderma harzianum were obtained mostly from rhizospheresoil using either general or special environme...

Agrocybe aegerita is an important mushroom cultivated in Korea, with good feel and a peculiar fragrance. A. aegerita can be cultivated throughout the year using culture bottles but is more susceptible to contamination than other mushrooms. Twenty-two pathogens were isolated from the fruiting bodies and compost of A. aegerita, and seven isolates were isolated from Pleurotus ostreatus to compare ...

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...

Members of genus Trichoderma are known worldwide for mycoparasitism. To gain a better insight into the organization and evolution of their genomes, we used an in silico approach to compare the occurrence, relative abundance and density of SSRs in Trichoderma atroviride, T. harzianum, T. reesei, and T. virens. Our analysis revealed that in all the four genome sequences studied, the occurrence, r...
