Fusarium Head Blight is an important wheat disease in the Argentine Pampas region, being Fusarium graminearum the predominant pathogen. DNA polymorphism of the isolates was analyzed by IGS-RFLP and ISSR. IGS-RFLP and ISSR profiling were carried out using six endonucleases and eight primers, respectively. IGS-RFLP yielded 41 bands, 30 of which were polymorphic while ISSR produced 87 bands with 4...

Fusarium Head Blight (FHB) emerged in the 1990’s as an important problem for American agriculture. Resolving the FHB problem involves cooperative efforts and a multidisciplinary approach, including analytical assays for vomitoxin in the new wheat and barley varieties. In 1999, the US Wheat and Barley Scab Initiative provided grants, for diagnostic vomitoxin (DON) services, to 4 laboratories in ...

Fusarium graminearum is a pathogenic fungus that causes Fusarium head blight in wheat and lowers the yield and quality of grains by contamination with the trichothecene mycotoxin deoxynivalenol. The fungi coexist and interact with several different fusaria as well as other plant pathogenic fungi and bacteria in the field. In Canada, F. graminearum exists as two main trichothecene chemotypes: 3-...

The ascomycete fungal pathogen Fusarium graminearum (teleomorph stage: Gibberella zeae) is the causal agent of Fusarium head blight in wheat and barley. This disease leads to significant losses of crop yield, and especially quality through the contamination by diverse fungal mycotoxins, which constitute a significant threat to the health of humans and animals. In recent years, high-throughput p...

A survey of Fusarium head blight (FHB)-contaminated wheat in Ethiopia recovered 31 isolates resembling members of the Fusarium graminearum species complex. Results of a multilocus genotyping (MLGT) assay for FHB species and trichothecene chemotype determination suggested that 22 of these isolates might represent a new species within the Fg complex. Phylogenetic analyses of multilocus DNA sequen...

ABSTRACT In experiments conducted in growth chambers with the susceptible wheat cultivar BR 23, interactions between five temperatures (10, 15, 20, 25 and 30°C) eleven wetting periods were assessed for fusarium head blight (FHB) intensity. Each temperature consisted of one experiment hours corresponded to treatments. The disease occurred even at 10ºC, minimum tested temperature, maximum inciden...

Fusarium head blight (FHB), mainly caused by graminearum, is one of the most devastating diseases wheat globally. FHB causes an extensive reduction in yield and reduces grain quality through its contamination with toxins such as deoxynivalenol (DON), T2 toxin, HT-2 nivalenol, zearalenone. This review provides overview updated progress genetic studies on resistance to FHB, emphasis sources gene/...
