| [study of the effect of volatile metabolites of trichoderma hamatum on the growth of phytopathogenic soilborne fungi.]. | volatile compounds produced by trichoderma hamatum were tested for their capacity to suppress in vitro the growth of alternaria citri, bipolaris cynodontis, bipolaris sorokiniana, curvularia brachyspora, curvularia lunata, curvularia oryzae-sativae, drechslera tritici-repentis, rhizoctonia solani, sclerotinia minor and sclerotium rolfsii. the organisms were cultured in an apparatus made with two erlenmeyer flasks assembled by their top parts. with the aid of the gas chromatographic technique the ... | 1997 | 17655390 |
| variation in occurrence of dematiaceous hyphomycetes on forage bermudagrass over years, sampling times, and locations. | abstract leaf samples of forage bermudagrass with symptoms of infection by species of bipolaris, curvularia, and exserohilum (dematiaceous hyphomycetes) were collected from three swine waste application sites in mississippi at eight sampling times during each of 3 years. samples were assayed for pathogens by observing sporulation on plated leaf tissue. among 3,600 leaves assayed, eight species of the three genera were observed. features and criteria for the practical identification of species on ... | 2005 | 18943471 |
| bipolaroxin, a selective phytotoxin produced by bipolaris cynodontis. | two sesquiterpenes have been isolated from the fungal pathogen of bermuda grass bipolaris cynodontis. chemical, spectral, and x-ray diffraction studies have led to the characterization of these as bipolaroxin and dihydrobipolaroxin, highly oxygenated members of the eremophilane family. bipolaroxin is phytotoxic to some but not all of the plants tested. to our knowledge, a phytotoxin with host selectivity isolated from a weed pathogen has not been reported previously. | 1985 | 3866223 |
| diversity of bipolaris species in clinical samples in the united states and their antifungal susceptibility profiles. | a set of 104 isolates from human clinical samples from the united states, morphologically compatible with bipolaris, were morphologically and molecularly identified through the sequence analysis of the internal transcribed space (its) region of the nuclear ribosomal dna (rdna). the predominant species was bipolaris spicifera (67.3%), followed by b. hawaiiensis (18.2%), b. cynodontis (8.6%), b. micropus (2.9%), b. australiensis (2%), and b. setariae (1%). bipolaris cynodontis, b. micropus, and b. ... | 2012 | 23052310 |
| the genus bipolaris. | the genus bipolaris includes important plant pathogens with worldwide distribution. species recognition in the genus has been uncertain due to the lack of molecular data from ex-type cultures as well as overlapping morphological characteristics. in this study, we revise the genus bipolaris based on dna sequence data derived from living cultures of fresh isolates, available ex-type cultures from worldwide collections and observation of type and additional specimens. combined analyses of its, gpdh ... | 2014 | 25492990 |
| subcutaneous mycosis due to cladosporium cladosporioides and bipolaris cynodontis from assam, north-east india and review of published literature. | a large number of phaeoid fungi cause infection in humans and other animals which is characterized by the basic development of sclerotic body, dark-coloured filamentous hyphae as well as yeast-like cells in the invaded tissue. two cases of subcutaneous mycosis in immunocompetent male patients aged 55 and 58 years attending dermatology outpatient department of a tertiary care hospital in assam, north-east india, are reported. the first case was diagnosed as chromoblastomycosis which was caused by ... | 2015 | 26198088 |
