Trichothecin, a toxic metabolite of Trichothecium roseum, was detected in 3 of 13 wheat samples examined at levels of 560, 290, and 270 ng/g. In addition, all the T. roseum isolates from the wheat produced the toxin on wheat.
BERNADOVIČOVÁ, S., IVANOVÁ, H. 2011. Hyphomycetes and Coelomycetes fungi isolated from affected leaves and twigs of cherry laurel trees. Folia oecol., 38: 137–145. The aim of this work was to identify fungi occurring on leaves and twigs of Prunus laurocerasus L. Mycological observations were carried out on leaves and twigs collected from symptomatic cherry laurels growing in green areas of the ...
A hyperparasite was observed on Venturia inaequalis during a survey in Krasnodar region, South Russia. Morphological characterization using light microscopy and molecular by sequencing ITS region of nuclear ribosomal DNA phylogenetic analysis revealed the identity pathogen as Trichothecium roseum. This is first record roseum from
Background: A total of 30 endophytic fungi (AAP-PS 1–30) were isolated from the medicinal herb Phyllanthus amarus and screened for the production of Trichothecinol-A. Out of all the endophytic strains screened for Trichothecinol-A production, the culture filtrate of AAP-PS-1 extracted with ethyl acetate yielded Trichothecinol-A extracellularly in appreciable amounts. Trichothecinol-A was purifi...
A new cyclodepsipeptide, designated roseocardin, was isolated from the culture broth of Trichothecium roseum TT103. Roseotoxin B and destruxins A and B were also isolated during the same procedure. The structure of roseocardin was determined by EI-MS, NMR and X-ray crystallographic analysis. Roseocardin as well as the other cyclodepsipeptides were shown to produce positive inotropic effects on ...
توس (birch) از درختان مهم جنگلهای شمال کشور است که در معرض انقراض قرار دارد. زادآوری طبیعی این گونهی با ارزش، به دلیل وجود عوامل محدود کننده ازجمله آفات و عوامل بیماری زا؛ به ویژه قارچها، با مشکلات فراوانی مواجه است. به منظور جداسازی و شناسایی قارچهای همراه بذر توس، بذرهای گونه pendula betula از جنگلهای سیامرزکوه استان گلستان و بذرهای گونه betula litwinowiiاز سنگده استان مازندران بهطور تص...
Various species of Absidia, Aspergillus, Cunninghamella, Trichothecium, Penicillium, and Phanerochaete were found to transform rotenone to one or more metabolites. Two biotransformation products were isolated from a preparative-scale incubation of rotenone with Cunninghamella blakesleeana and identified as 1',2'-dihydro-1',2'-dihydroxyrotenone and 3'-hydroxyrotenone (amorphigenin). The catalyti...
Two new cyclodepsipeptides (1 and 2), two new sesquiterpenoids (3 and 4), and the known compounds guangomide A (5), roseotoxin S, and three simple trichothecenes were isolated from the cytotoxic organic extract of a terrestrial filamentous fungus, Trichothecium sp. The structures were determined using NMR spectroscopy and mass spectrometry. Absolute configurations of the cyclodepsipeptides were...
