Spore Killer Polymorphism in FUSARIUM MONILIFORME.
A Spore killer trait, which exhibits genetic and cytological properties analogous to those previously found in Neurospora, exists in natural populations of the fungal plant pathogen Fusarium moniliforme. The genogeography of the polymorphism in F. moniliforme differs from the situation in Neurospora intermedia. It is more akin to the situation in N. sitophila, although more extreme with respect...
متن کاملBiological control of Fusarium moniliforme in maize.
Fusarium moniliforme Sheldon, a biological species of the mating populations within the (italic)Gibberella fujikuroi species complex, i.e., population A [= G. moniliformis (Sheld.) Wineland], is an example of a facultative fungal endophyte. During the biotrophic endophytic association with maize, as well as during saprophytic growth, F. moniliforme produces the fumonisins. The fungus is transmi...
متن کاملNitrate reduction mutants of fusarium moniliforme (gibberella fujikuroi).
Twelve strains of Fusarium moniliforme were examined for their ability to sector spontaneously on toxic chlorate medium. All strains sectored frequently; 91% of over 1200 colonies examined formed chlorate-resistant, mutant sectors. Most of these mutants had lesions in the nitrate reduction pathway and were unable to utilize nitrate (nit mutants). nit mutations occurred in seven loci: a structur...
متن کاملDisseminated infection by Fusarium moniliforme during treatment for malignant lymphoma.
Disseminated infection caused by Fusarium moniliforme is described in a 32-year-old granulocytopenic man with malignant lymphoma being treated with cytotoxic drugs and corticosteroids. Infected skin denuded by antecedent severe varicella-zoster infection was the probable source of fungemia. F. moniliforme grows rapidly on common mycological media as a lavender- to violet-colored mold at 25 to 3...
متن کاملBiotransformation of Steviol Derivatives by Aspergillus niger and Fusarium moniliforme
Derivados do esteviol foram submetidos a biotransformações por fungos. O ent-11β,13-diidróxi15,16-epoxicauran-19-oato de metila foi hidroxilado em C-11 por Aspergillus niger enquanto que o ácido ent-16β-hidróxibaierano-19-óico foi hidroxilado em C-6 e C-7 pelo Fusarium moniliforme. A hidroxilação em posições não ativadas do esqueleto carbônico é discutida tendo em vista as propriedades de impor...
