Spring barley is grown on about half of the Norwegian cereal area. The rest of the area is equally divided between wheat and oats. Most years the domestic production provides 70%-80% of the domestic market for bread wheat. Barley and oats are mainly grown for animal feed. During the years 2008-2012, severe epidemics of Fusarium head blight have led to increased mycotoxin contamination of cereal...

Eukaryotic cells repress global translation and selectively upregulate stress response proteins by altering multiple steps in gene expression. In this study, genome-wide transcriptome analysis of cellular adaptation to thermal stress was performed on the plant pathogenic fungus Fusarium graminearum. The results revealed that profound alterations in gene expression were required for heat shock r...

Fusarium graminearum (teleomorph Gibberella zeae) is a significant pathogen of wheat and corn. F. graminearum forms multicellular macroconidia that play an important role in dissemination of the disease. The spatial pattern of morphogenesis in germinating macroconidia is described. Germ tubes preferentially emerge from the apical cells in a bipolar pattern that appears to be common to filamento...

the life history of an acarid mite, tyrophagus putrescentiae (schrank), on fusarium graminearum clade was investigated at 25 â± 1â°c, 60 â± 5% rh and a photoperiod of 16: 8 (l: d) h. incubation period for egg hatch, larval and nymphal periods and adult longevity were 2.22 â± 0.06, 3.46 â± 0.12, 4.84 â± 0.16 and 10.05 â± 0.9 days, respectively. the average life span of males and females were 22....

Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops such as wheat, barley, and maize. Both sexual (ascospores) and asexual (conidia) spores are produced in F. graminearum. Since conidia are responsible for secondary infection in disease development, our objective of the present study was to reveal the molecular mechanisms underlying conidiog...

Fusarielins are polyketides with a decalin core produced by various species of Aspergillus and Fusarium. Although the responsible gene cluster has been identified, the biosynthetic pathway remains to be elucidated. In the present study, members of the gene cluster were deleted individually in a Fusarium graminearum strain overexpressing the local transcription factor. The results suggest that a...

Fungal aldoxime dehydratase (Oxd) of Fusarium graminearum MAFF305135 was purified and characterized for the first time from its overexpressing Escherichia coli transformant. The enzyme showed about 20% identity with known Oxds, and had similar enzymatic properties with nitrilase-linked Oxd from the Bacillus strain. It belongs to a group of phenylacetaldoxime dehydratases (EC 4.99.1.7), based on...

We report the use of three glycosidase inhibitors, the bean polygalacturonase inhibiting protein 2 (PvPGIP2), the kiwi pectin methyl esterase inhibitor (AcPMEI), and the Triticum aestivum xylanase inhibitor III (TAXI-III), to control leaf blotch and Fusarium Head Blight (FHB) symptoms caused by the fungal pathogens Bipolaris sorokiniana and Fusarium graminearum. We produced transgenic durum whe...

Aims: To analyze phenolic compounds and evaluate antifungal activity of methanolic and ethanolic extract's from Cymbopogon citratus against Fusarium graminearum and Fusarium oxysporum sp tulipae. Study Design: Activity directed antifungal activity, total phenolic compounds determination, total antioxidant determination and High Performance Liquid Chromatography (HPLC) phenolic compounds analysi...
