| phylogenetic ordinal placement based on rdna sequences of the freshwater genera ophioceras and pseudohalonectria. | the ordinal placement of two closely related freshwater genera, ophioceras and pseudohalonectria, was assessed by using phylogenetic analysis of morphological characters, partial sequences of the large subunit ribosomal dna and restriction site variations in the internal transcribed spacer (its). the two genera have some morphological features that are used to define taxa in both the sordariales and diaporthales, and, hence, their phylogenetic relationships are unclear. equally weighted analyses ... | 1995 | 7553269 |
| trichothecene production by trichoderma brevicompactum. | trichoderma brevicompactum, t. viride, t. harzianum, t. atroviride, t. longibrachiatum, t. erinaceum, t. citrinoviride, and hypocrea lutea were screened for production of trichothecenes after growth on one or several solid and liquid media. trichothecenes were detected by liquid chromatography combined with online uv/vis spectroscopy and electrospray high-resolution mass spectrometry. t. brevicompactum produced trichodermin and/or harzianum a on all media investigated, with liquid media yielding ... | 2005 | 16218663 |
| 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 |
| trichoderma brevicompactum sp. nov. | trichoderma brevicompactum, a new species, was isolated from soil or tree bark in north, central and south america, including the caribbean islands, and southwestern and southeastern asia. morphological and physiological characters, the internal transcribed spacer regions of the rdna cluster (its1-5.8srdna-its2) and partial sequences of translation elongation factor 1-alpha (tef1) are described. trichoderma brevicompactum is characterized by a pachybasium-type morphology, morphologically resembl ... | 2004 | 21148926 |
