| isolation and liquid chromatographic determination of the cyclic peptide mycotoxin cyclosporin a from rice. | a simple method for determination and quantitation of a cyclic peptide mycotoxin, cyclosporin a, in rice is presented. rice inoculated with trichoderma polysporum (link ex pers.) was extracted with methylene chloride after 4 weeks of incubation. cyclosporin a was isolated from extracts by using open bed gel filtration column chromatography (lh-20, acetonitrile) and monitored with thin layer chromatography and reverse phase liquid chromatography coelution with a standard. preliminary thin layer c ... | 1987 | 3558265 |
| suppression of in vitro lymphocyte reactivity by cyclosporin a: existence of a population of drug-resistant cytotoxic lymphocytes. | cyclosporin a (cs-a) is an unusual endecapeptide isolated from the fungi cylindrocarpon lucidum booth and trichoderma polysporum. it is a potent immunosuppressive drug that prevents rejection of kidney and heart allografts whilst having a low myelotoxicity. its mode of action is still unclear but its main target appears to be the t lymphocyte. the mixed lymphocyte reaction (mlr) and cell-mediated lymphocytoxicity (cml) used here are generally regarded as in vitro correlates of allograft rejectio ... | 1980 | 6447256 |
| pathway for ca2+ influx into cells by trichosporin-b-via, an alpha-aminoisobutyric acid-containing peptide, from the fungus trichoderma polysporum. | trichosporin (ts) -b-via, a fungal alpha-aminoisobutyric acid (aib) -containing peptide consisting of 19 amino acid residues and a phenylalaninol, produced both 45ca2+ influx into bovine adrenal chromaffin cells and catecholamine secretion from the cells. the secretion induced by ts-b-via at lower concentrations (2-5 microm) was completely dependent on the external ca2+, while that induced by ts-b-via at higher concentrations (10-30 microm) was partly independent of the ca2+. the concentration-r ... | 1996 | 8679651 |
| peptidic immunosuppressants from the fungus trichoderma polysporum. | three new 10-residue lipopeptaibols, trichopolyns iii-v have been isolated from the fungus trichoderma polysporum together with the known trichopolyns i and ii. structure determination has been achieved on the basis of spectroscopic and chemical evidence. these peptides have been shown to suppress the proliferation of lymphocytes in mouse allogeneic mixed lymphocyte reaction. | 1999 | 10617078 |
| genetic relatedness of trichoderma sect. pachybasium species based on molecular approaches. | molecular approaches including internal transcribed spacer (its) sequences of ribosomal dna, universal primer polymerase chain reaction (up-pcr) fingerprinting, and dna-dna hybridization were used to study the genetic relatedness of species within trichoderma sect. pachybasium. in the analysis of its and 5.8s sequences of ribosomal dna, parsimony analysis demonstrated that forty-one strains were distributed into five main groups supported by high bootstrap values. the species of trichoderma sect ... | 2002 | 12455615 |
| trichoderma taxi sp. nov., an endophytic fungus from chinese yew taxus mairei. | trichoderma taxi sp. nov. was isolated as an endophytic fungus of taxus mairei growing at the guanshan nature reserve of jiangxi province, china, and characterized by a combination of phenotypic characteristics and gene analyses of its1 and 2, tef1 and rpb2 gene sequences. distinctive morphological characters of trichoderma taxi are its white small subglobose conidia and pachybasium-like conidiophores aggregated into compact pustules. phylogenetically, trichoderma taxi forms an independent branc ... | 2007 | 17302921 |
| biochemical characterization of biocontrol agents used for control of root pathogens. | due to low microbial biodiversity in the nutrient solution and the root, open and closed hydroponic systems are regarded as sensitive from biological point of view. this is of particular importance as an enhanced spread of root pathogen may occur in closed hydroponic systems and possibilities for chemical control are restricted. biocontrol agents appear to be a feasible alternative. for an effective use of these agents, knowledge on the behaviour, external requirements and the specific capabilit ... | 2006 | 17390847 |
| microfungi associated with abies needles and betula leaf litter in a subalpine coniferous forest. | we investigated microfungal assemblages on leaf litter within a subalpine forest in central japan and their variation with season, litter depth, and litter species. microfungal assemblages were compared for abies needles and betula leaf litter collected from litter and fermentation layers of the forest floor during the growing season in spring, summer, and autumn. a total of 35 and 42 species were isolated from abies needles and betula leaf litter, respectively. the observed variation in microfu ... | 2007 | 17496944 |
| plant community influences on soil microfungal assemblages in boreal mixed-wood forests. | we studied the relationships between assemblages of soil microfungi and plant communities in the southern boreal mixed-wood forests of quebec. sampling took place in 18,100 m2 plots from an existing research site. plots were separated into three categories based on dominant overstory tree species: (i) trembling aspen, (ii) white birch and (iii) a mixture of white spruce and balsam fir. within each plot a 1 m2 subplot was established in which the understory herbaceous layer was surveyed and soil ... | 2007 | 17883027 |
| isolation of fungi from heterodera glycines and in vitro bioassays for their antagonism to eggs. | twenty fungi were assayed in vitro for antagonism to eggs of heterodera glycines. eight of the fungi were isolated from cysts or eggs of h. glycines during the current study, one was isolated from panagrellus redivivus, and eleven were obtained from other researchers or collections. the bioassays were conducted on eggs from nematodes that had been grown monoxenically on excised root tips. phoma chrysanthemicola, one strain of verticillium chlamydosporium, and one strain of v. lecanii caused a de ... | 1990 | 19287754 |
| expression of transforming growth factor-beta and determination of apoptotic index in histopathological sections for assessment of the effects of apigenin (4', 5', 7'- trihydroxyflavone) on cyclosporine a induced renal damage. | cyclosporine a (csa), a calcineurin inhibitor produced by the fungi trichoderma polysporum and cylindrocarpon lucidum, is an immunosuppressant prescribed in organ transplants to prevent rejection. its adverse effect on renal dysfunction has limited its use in a clinical setting. apigenin (4',5',7'-trihydroxyflavone), a herbal extract, with anti-inflammatory and anti-tumour properties, has been investigated for properties to reverse this adverse effect. this research was conducted to establish a ... | 2009 | 19694312 |
