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 antagonism ability of the15 species fungi associated with rot roots disease against the pathogen R.solani showed growth fungus T. harzianumwas faster than R.s which cover all area perti plate antagomism degree 1.33. A field experiment was carried out in 2011/2012 Agriculture College /Tikrit University for test induction a systemic resistance by harzianumagainst root caused three cultivars b...

A pot experiment was conducted with the single and combined doses of fungicides, plant extracts antagonist for management nine rice pathogens. total 13 treatments including controls or without inocula pathogen were tested. Amongst all only T6 (Bavistin + Azadirachta indica Trichoderma harzianum) showed highest percentage seed germination seedling vigor index seeds inoculated Alternaria alternat...

The phosphodiesterase 6 gamma (PDE6 gamma) inhibitory subunit of the rod PDE6 effector enzyme plays a central role in the turning on and off of the visual transduction cascade, since binding of PDE6 gamma to the transducin alpha subunit (T alpha) initiates the hydrolysis of the second messenger cGMP, and PDE6 gamma in association with RGS9-1 and the other GAP complex proteins (G beta 5, R9AP) a...

Five temperature-sensitive growth mutants of the hamster cell line BHK-21 were tested for the ability to support adenovirus 2 multiplication at 39 degrees and 33 degrees. Wild-type BHK-21 and mutants ts 422E and ts BCH yielded comparable amounts of virus at 33 degrees and 39 degrees, whereas in three other mutants, ts T22, ts T23, and ts AF8, virus production at 39 degrees was reduced to about ...

Knowledge on the factors that determine the composition of bacterial communities in the vicinity of roots (rhizosphere) is essential to understand plant-soil interactions. Plant species identity, plant growth stage and soil properties have been indicated as major determinants of rhizosphere bacterial community composition. Here we show that the presence of saprotrophic fungi can be an additiona...

BACKGROUND The conversion of biomass-derived sugars via enzymatic hydrolysis for biofuel production is a challenge. Therefore, the search for microorganisms and key enzymes that increase the efficiency of the saccharification of cellulosic substrates remains an important and high-priority area of study. Trichoderma harzianum is an important fungus known for producing high levels of cellulolytic...
