| taxonomy and phylogeny of the fusarium dimerum species group. | the morphospecies fusarium dimerum, known only from its anamorph, comprises at least 12 phylogenetically distinct species. analyses of the large subunit ribosomal dna (lsu rdna) show they are taxa of the nectriaceae (hypocreales), related to f. domesticum and form a phylogenetically distinct clade within fusarium. fusarium dimerum, for which no herbarium material could be located, is characterized by macroconidia with a single, median septum, according to the original description and illustratio ... | 2009 | 19271670 |
| indole-3-acetic acid biosynthesis in fusarium delphinoides strain gpk, a causal agent of wilt in chickpea. | fusarium delphinoides (ascomycota; nectriaceae) is an indole-3-acetic acid (iaa) producing plant pathogen and a causal agent of wilt in chickpea. the iaa biosynthetic pathway in f. delphinoides strain gpk (fdg) was examined by analyzing metabolic intermediates and by feeding experiments. gas chromatograph (gc) analysis of fdg culture filtrates showed the presence of metabolic intermediates of indole-3-pyruvic acid (ipya), indole-3-acetamide (iam), and tryptamine (tra) pathways. the different iaa ... | 2013 | 23306880 |
