چکیده
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 medicarpin is first demethylated to 3,9-dihydroxypterocarpan.

The Transaldolase, a Novel Allergen of Fusarium proliferatum, Demonstrates IgE Cross-Reactivity with Its Human Analogue
Fusarium species are among airborne fungi and recognized as causative agents of human atopic disorders. However, Fusarium allergens have not been well characterized and the lack of information limits clinical diagnosis and treatment of fungal allergy. The purpose of this study is to identify and characterize important allergens of F. proliferatum. IgE-reacting F. proliferatum components were id...
متن کاملInfluence of Butylated Hydroxyanisole on the Growth, Hyphal Morphology, and the Biosynthesis of Fumonisins in Fusarium proliferatum
Fusarium proliferatum as a common fungus pathogen in foods can produce toxic fumonisins, which can cause animal diseases and increase risks of human cancers. On contrary, butylated hydroxyanisole (BHA) as a synthetic antioxidant offers a clue for preventing growth of fungal species and inhibiting production of mycotoxins. Unfortunately, information of the inhibitory mechanism of BHA on Fusarium...
