Fusarium head blight (FHB) of wheat has become a serious threat to wheat crops in numerous countries. In addition to loss of yield and quality, this disease is of primary importance because of the contamination of grain with mycotoxins such as deoxynivalenol (DON). The Swiss winter cultivar Arina possesses significant resistance to FHB. The objective of(More)
Fusarium head blight (FHB) is an important disease of wheat worldwide. Soissons is one of the most resistant varieties grown in UK. The current study was undertaken to identify QTL for FHB resistance in Soissons and to determine whether the semi-dwarfing alleles Rht-B1b and Rht-D1b have a similar influence on susceptibility to FHB. A Soissons (Rht-B1b;(More)
The Fusarium species Fusarium graminearum and Fusarium culmorum, which are responsible for Fusarium head blight (FHB) disease, reduce world-wide cereal crop yield and, as a consequence of their mycotoxin production in cereal grain, impact on both human and animal health. Their study is greatly promoted by the availability of the genomic sequence of F.(More)
ABSTRACT Over 4 years, the environmental conditions and the causal agents of Fusarium head blight (FHB) disease of wheat were determined in field sites in four European countries: Hungary, Ireland, Italy, and the United Kingdom. Polymerase chain reaction-based methods were used to detect each species causing FHB and quantify its DNA (as a measurement of(More)
Research on the pathogen components involved in Fusarium head blight (FHB) along with the effects of their interactions on disease development and mycotoxin accumulation is reviewed. The fungal components within the FHB complex differ significantly in different environments. Individual species may respond differently to, and be differentially influenced by,(More)
This study was conducted to assess evolutionary relationships, species diversity and trichothecene toxin potential of five Fusarium graminearum complex (FGSC) isolates identified as genetically novel during prior Fusarium head blight (FHB) surveys in Nepal and Louisiana. Results of a multilocus genotyping (MLGT) assay for B-trichothecene species(More)
Fusarium head blight (FHB) is an important disease of wheat worldwide. The cultivar Spark is more resistant than most other UK winter wheat varieties but the genetic basis for this is not known. A mapping population from a cross between Spark and the FHB susceptible variety Rialto was used to identify quantitative trait loci (QTL) associated with(More)
Published research on the effects of fungal interaction on disease development and subsequent mycotoxin accumulation was reviewed, focusing on pathogens related to Fusarium Head Blight (FHB). Almost all published studies showed that competitive interactions are the rule when fungal/disease development is considered. The fungi with the competitive advantage(More)
Isolates of the type-A trichothecene producing Fusarium sporotrichioides and Fusarium langsethiae were grouped and differentiated in a phylogenetic tree using ITS sequence dissimilarity. An attempt was made to develop a PCR-based assay for the detection and differentiation of Fusarium sporotrichiodes from other Fusarium species using the 5'-region of the(More)
Ethylene signalling affects the resistance of dicotyledonous plant species to diverse pathogens but almost nothing is known about the role of this pathway in monocotyledonous crop species. Fusarium graminearum causes Fusarium head blight (FHB) of cereals, contaminating grain with mycotoxins such as deoxynivalenol (DON). Very little is known about the(More)
