anthrotainin, an inhibitor of substance p binding produced by gliocladium catenulatum. | substance p (sp) is an undecapeptide belonging to a family of chemically related neurotransmitters and neuromodulators known as neurokinins. in our search for sp antagonists, we screened microbial broth extracts for the ability to inhibit radiolabeled sp binding to membranes prepared from rat forebrain. anthrotainin was isolated from a fungal culture and determined to be a novel tetracyclic compound, with an ic50 of 3 microm against [125i]sp. the structure, spectroscopic, chemical, and pharmacol ... | 1993 | 7682212 |
new verticillin and glisoprenin analogues from gliocladium catenulatum, a mycoparasite of aspergillus flavus sclerotia | four new compounds (1-4) have been isolated from solid-substrate fermentation cultures of the sclerotial mycoparasite gliocladium catenulatum. the structures of verticillins d (1), e (2), and f (3) were assigned on the basis of ms and nmr data and chemical derivatization. the structure of glisoprenin f (4) was assigned by analysis of ms and nmr results, and comparison of its spectral data to those of the known compound glisoprenin d (6). | 1999 | 10346956 |
new sequences and new fungal producers of peptaibol antibiotics antiamoebins. | mixtures of the microheterogeneous 16-mer peptaibol antibiotics called antiamoebins (aam) have been isolated from the culture broths of strains of the filamentous fungi stilbella erythrocephala atcc 28144, stilbella fimetaria cbs 548.84 and gliocladium catenulatum cbs 511.66. sequences were determined using on-line hplc together with positive- and negative-ion electrospray ionization mass spectrometry. some characteristic features are recognized in the mass spectrometric fragmentation pattern of ... | 2000 | 10809388 |
production of a monoclonal antibody specific to the genus trichoderma and closely related fungi, and its use to detect trichoderma spp. in naturally infested composts. | studies of the interactions between hyperparasitic fungi and their hosts are severely hampered by the absence of methods that allow the unambiguous identification of individual genera in complex environments that contain mixed populations of fungi, such as soil or compost. this study details the development of a monoclonal antibody (mf2) that allows the detection and recovery of trichoderma spp. in naturally infested composts, and the visualization of hyperparasitic strains of trichoderma during ... | 2002 | 11988501 |
diversity of endophytic fungal community of cacao (theobroma cacao l.) and biological control of crinipellis perniciosa, causal agent of witches' broom disease. | the basidiomycete fungus crinipellis perniciosa (stahel) singer is the causal agent of witches' broom disease of cacao (theobromacacao l.) which is the main factor limiting cacao production in the americas. pod losses of up to 90% are experienced in affected areas as evidenced by the 50% drop in production in bahia province, brazil following the arrival of the c. perniciosa in the area in 1989. the disease has proven particularly difficult to control and many farmers in affected areas have given ... | 2005 | 15951847 |
viability of heterodera glycines exposed to fungal filtrates. | filtrates from nematode-parasitic fungi have been reported to be toxic to plant-parasitic nematodes. our objective was to determine the effects of fungal filtrates on second-stage juveniles and eggs of heterodera glycines. eleven fungal species that were isolated from cysts extracted from a soybean field in florida were tested on j2, and five species were tested on eggs in vitro. each fungal species was grown in czapek-dox broth and malt extract broth. no toxic activity was observed for fungi gr ... | 2000 | 19270965 |
pathogenicity of fungi to eggs of heterodera glycines. | twenty-one isolates of 18 fungal species were tested on water agar for their pathogenicity to eggs of heterodera glycines. an egg-parasitic index (epi) for each of these fungi was recorded on a scale from 0 to 10, and hatch of nematode eggs was determined after exposure to the fungi on water agar for 3 weeks at 24 c. the epi for verticillium chlamydosporium was 7.6, and the fungus reduced hatch 74%. pyrenochaeta terrestris and two sterile fungi also showed a high epi and reduced hatch 42-73%. ar ... | 1996 | 19277130 |
fungi associated with females and cysts of heterodera glycines in a florida soybean field. | fungal colonization was determined for females and cysts of heterodera glycines on soybean roots or in rhizosphere soil from a florida soybean field. a total of 1,620 females and cysts were examined in 1991, and 1,303 were examined in 1992. more than 35 species of fungi were isolated from females and cysts. the frequency of fungi colonizing white and yellow females was low, but a high frequency of fungi was encountered in brown cysts, which increased with time of exposure of the cysts to the soi ... | 1994 | 19279895 |
chitinase and beta-1,3-glucanase enzyme production by the mycoparasite clonostachys rosea f. catenulata against fungal plant pathogens. | clonostachys rosea f. catenulata (syn. gliocladium catenulatum) is an effective fungal biological agent against fusarium root and stem rot and pythium damping-off diseases on cucumber plants. both chitinase and beta-1,3-glucanase enzymes were produced when c. rosea was grown on a synthetic medium containing chitin or laminarin as a sole carbon source, respectively. chitinase production was also induced by fusarium cell walls, while beta-1,3-glucanase activity was induced by both fusarium and pyt ... | 2009 | 19396235 |
a laboratory evaluation to determine the compatibility of microbiological control agents with the pollinator bombus terrestris. | this study was undertaken to identify any potential adverse side effects of the use of seven microbiological control agents (mcas) on the bumblebee, bombus terrestris l., in the context of combined use in integrated pest management (ipm). aq10 (ampelomyces quisqualis), binab-t-vector (hypocrea parapilulifera + t. atroviride; 1/1), prestop-mix (gliocladium catenulatum j1446), serenade (bacillus subtilis qst713), trianum-p (trichoderma harzianum t22), botanigard (beauveria bassiana gha) and granup ... | 2009 | 19437453 |

a perilipin gene from clonostachys rosea f. catenulata hl-1-1 is related to sclerotial parasitism. | clonostachys rosea f. catenulata is a promising biocontrol agent against many fungal plant pathogens. to identify mycoparasitism-related genes from c. rosea f. catenulata, a suppression subtractive hybridization (ssh) cdna library of c. rosea f. catenulata hl-1-1 that parasitizes the sclerotia of s. sclerotiorum was constructed. 502 clones were sequenced randomly, and thereby 472 expressed sequence tags (ests) were identified. forty-three unigenes were annotated and exhibited similarity to a wid ... | 2015 | 25761240 |
reliability of the entomovector technology using prestop-mix and bombus terrestris l. as a fungal disease biocontrol method in open field. | botrytis cinerea pers.:fr. is a major plant pathogen, and a new approach is needed for its control in strawberry to minimise the increasing use of synthetic fungicides. the biofungicide prestop-mix, which contains gliocladium catenulatum, is effective against botrytis infections; however, the need for frequent applications increases the costs for farmers. here, we demonstrate that bumble bees, bombus terrestris l., effectively disseminate the preparation onto flowers in open field conditions. ov ... | 2016 | 27530075 |
