to evaluate the effect of glomus mosseae and trichoderma virens, on root knot nematode (meloidogyne spp.) in tomato plants, a greenhouse experiment was performed in a completely randomized design with seven treatments in four replicates. t. virens was isolated from the wheat fields of fars province and cultured on pda medium. g. mosseae provided from the department of horticulture, university o...

the effect of different isolates of trichoderma namely t. virens t65, t virens t90, t. virens t96, t. virens t122, t. brevicompactum t146, t. koningiopsis t149, t. viridecense t150, t. koningii as well as two trichodermin b and subtilin commercial bioproducts on growth promotion in wheat were studied through seed coating method in a compeletly randomized design in a glasshouse experiment. the i...

Fungi belonging to the genus Trichoderma, commonly found in soil or colonizing plant roots, exert beneficial effects on plants, including the promotion of growth and the induction of resistance to disease. T. virens and T. atroviride secrete the proteins Sm1 and Epl1, respectively, which elicit local and systemic disease resistance in plants. In this work, we show that these fungi promote growt...

The interactions of crops with root-colonizing endophytic microorganisms are highly relevant to agriculture, because endophytes can modify plant resistance pests and increase crop yields. We investigated the between host Zea mays fungus Trichoderma virens at 5 days postinoculation grown in a hydroponic system. Wild-type T. two knockout mutants, deletion genes tv2og1 or vir4 involved specialized...

Ustiloxin D, produced by the rice plant pathogen Ustilaginoidea virens, exhibits potent anti-tubulin activity. In order to elucidate the effects of functional groups in ustiloxin D on its activity, several derivatives were synthesized and their anti-tubulin activities were estimated. The N,N-dimethylamino derivative and the 14-O-methyl derivative were inactive (IC50 > 50 microM). 20-Hydroxymeth...
