Isoflavones, Fusarium, Methylation, Demethylation, 3'-Hydroxylation, Metabolism Several introductionary reactions of isoflavone metabolism by Fusarium fungi are reported. Fu­ sarium avenaceum hydroxylates formononetin in the 3'-position yielding 3',7-dihydroxy-4'-methoxyisoflavone (calycosin). 3'-Hydroxylation of biochanin A to 3/,5,7-trihydroxy-4/-methoxyisoflavone (pratensein) has been observ...

Abstract Due to global shifts in climate, studies contrasting conditions of two natural and climatic zones are particular interest: (1) subzone mixed broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, therefore increase loss quality materials. The frequency occurrence mycoses autumn is 2-14 tim...

Fusarium head blight (FHB) is a devastating fungal disease of small-grain cereals that causes significant yield losses and mycotoxin contamination, diminishing food feed safety worldwide. In contrast to wheat, little known about the agricultural practices influence FHB mycotoxins in barley. Thus, nationwide survey was conducted across Switzerland for harvest samples 2016 2017, accompanied with ...

The increased occurrence of Fusarium-mycotoxins in Norwegian cereals over the last decade, is thought to be caused by increased inoculum resulting from more cereal residues at the soil surface as a result of reduced tillage practices. In addition, weather conditions have increasingly promoted inoculum development and infection by Fusarium species. The objective of this work was to elucidate the...

BACKGROUND Tyrophagus putrescentiae (Acari: Astigmata) and Fusarium sp. co-occur in poorly managed grain. In a laboratory experiment, mite grazing resulted in significant reduction of fungal mycelium on cultivation plates. The destruction of mycelium appeared to be a result of an interaction between the mites, fungi and associated bacteria. METHODOLOGY AND PRINCIPAL FINDINGS A laboratory expe...

Several species of the genus Fusarium can cause apple fruit to rot while stored. Since Fusarium taxonomy is very complex and has constantly been revised and updated over the last years, the aim of this study was to identify Fusarium species from rotten apples, based on combined morphological characteristics and molecular data. We identified 32 Fusarium isolates from rotten apple fruit of cultiv...

To assess the potential for mating in several Fusarium species with no known sexual stage, we developed degenerate and semidegenerate oligonucleotide primers to identify conserved mating type (MAT) sequences in these fungi. The putative alpha and high-mobility-group (HMG) box sequences from Fusarium avenaceum, F. culmorum, F. poae, and F. semitectum were compared to similar sequences that were ...
