Degradation of 3,9-Dimethoxypterocarpan and Medicarpin by Fusarium proliferatum

Phytoalexins, 3,9-Dimethoxypterocarpan, Medicarpin, Fusarium, Degradation, Demethylation The degradation of 3,9-dimethoxypterocarpan was investigated in selected strains of Fusarium. Fusarium proliferatum (/'. e. Gibberella fujikuroi (SAW)WR) degrades this substrate via 3-methoxy-9-hydroxypterocarpan, 3,9-dihydroxypterocarpan and 2',4',7-trihydroxyisoflavan. During degradation by this organism ...

Wheat kernel black point and fumonisin contamination by Fusarium proliferatum.

Fusarium proliferatum is a major cause of maize ear rot and fumonisin contamination and also can cause wheat kernel black point disease. The primary objective of this study was to determine whether nine F. proliferatum strains from wheat from Nepal can cause black point and fumonisin contamination in wheat kernels. For comparison, the study included three Fusarium strains from US maize. In test...

Mycotoxins Biosynthesis by Fusarium Oxysporum and F. Proliferatum Isolates of Asparagus Origin

The subject of this work was fumonisin B1 (FB1) and moniliformin (MON) biosynthesis by three isolates of Fusarium oxysporum and three isolates of F. proliferatum of asparagus spears origin. The cultures of fungi were grown on rice and asparagus media for 3 weeks at 20oC. Experiment was carried out in 3 replicates. FB1 and MON occurrence was evaluated with high-performance liquid chromatography ...

Enhancing nitrilase production from Fusarium proliferatum using response surface methodology

The individual and interactive effects of three independent variables i.e. carbon source (glucose), nitrogen source (sodium nitrate) and inducer (ϵ-caprolactam) on nitrilase production from Fusarium proliferatum were investigated using design of experiments (DOE) methodology. Response surface methodology (RSM) was followed to generate the process model and to obtain the optimal conditions for m...

Restoration of gibberellin production in Fusarium proliferatum by functional complementation of enzymatic blocks.

Nine biological species, or mating populations (MPs), denoted by letters A to I, and at least 29 anamorphic Fusarium species have been identified within the Gibberella fujikuroi species complex. Members of this species complex are the only species of the genus Fusarium that contain the gibberellin (GA) biosynthetic gene cluster or at least parts of it. However, the ability of fusaria to produce...
