(Submitter supplied) Fusarium graminearum is responsible for Fusarium head blight (FHB), which is a destructive disease of wheat that makes its quality unsuitable for end use. To understand the temporal molecular response against this pathogen, microarray gene expression analysis was carried out at two time points on three wheat genotypes, the spikes of which were infected by Fusarium graminearum. The greatest number of genes was upregulated in Nobeokabouzu-komugi followed by Sumai 3, whereas the minimum expression in Gamenya was at three days after inoculation (dai). more...

(Submitter supplied) We report differentially expressed genes in four wheat genotypes, Nyubai, Wuhan 1 and their progeny line HC374, shaw associated with resistance and susceptibility against Fusarium Head Blight (FHB). Our result indicates an early up-regulation of LRR-RKs distinct between susceptible and resistant genotypes; subsequently, different sets of genes associated with defense response were up-regulated. Differences in expression profiles among the resistant genotypes indicate genotype specific defense mechanisms. more...

(Submitter supplied) In this study, early infection by F. graminearum was characterized in a doubled-haploid population derived from the cross of the moderately FHB resistant wheat genotypes Wuhan 1 and Nyubai. Three significant QTL were identified: 1AL was associated with reduced deoxynivalenol levels, and 4BS and 5A were associated with reduced F. graminearum levels at 2 days after infection. The early resistance alleles for 1AL and 4BS were inherited from Wuhan 1, and those for the 5A QTL were inherited from Nyubai. more...

(Submitter supplied) Multiple molecular tools and assays were deployed to compare the resistant variety Sumai3 with three regionally adapted Canadian cultivars, Stettler, Muchmore and FL62R1. Macroscopic and microscopic disease evaluation established the relative level of Type II FHB resistance of the four varieties and revealed that the F. graminearum (Fg) infection process displayed substantial temporal differences among organs. more...

(Submitter supplied) Fusarium head blight (FHB), caused by Fusarium graminearum, is a detrimental disease that affects small grains such as wheat around the world. Management of FHB is difficult, and improved methods of surveillance as well as a better understanding of pathogen aggressiveness are needed for improved control. F. graminearum disease severity varies depending on the resistance of the host genotype. In this study, we used the field pathogenomics method to investigate gene expression and population structure of isolates collected from wheat lines of varying resistance levels (susceptible, intermediate, and resistant) as well as an axenic control. more...

(Submitter supplied) In this study, we used the Affymetrix wheat GeneChip to examine the transcript accumulation in a near-isogenic line pair carrying resistant and susceptible alleles at the wheat Fhb1 locus. The objectives of this study were: (1) to identify the overall response in wheat to F. graminearum infection; (2) to identify key genes involved in FHB resistance/susceptibility pathways in wheat; (3) to compare the transcript profiles of wheat and barley during F. more...

(Submitter supplied) A comparative transcriptomic analysis of the responses arising 24 hours after infection of the susceptible T. aestivum variety ‘Fielder’, by Fg with co-application of either abscisic acid (ABA), gibberellic acid (GA) or the ABA-signaling inhibitor AS6, compared to stand-alone treatments is reported. Relevance of transcriptomic responses were assessed by differential expression feature evaluations (DEFE), highlighting that co-applied GA elicits a relatively strong opposing influence on Fg modulated genes, while co-applied ABA elicits similar responses to Fg. more...

(Submitter supplied) Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes) and developing seeds. This study compare the gene expression profile in wheat spikelets (spk 2) inoculated with either water (mock treatment) or a pathogenic strain of Fusarium graminearum (WT); spikelets 2 were inoculated 24 hrs after a neighbour spikelet (spk 0) was treated with either water or F. more...

(Submitter supplied) The ditelocentric addition line CS-7EL of the spring wheat (Triticum aestivum) cultivar Chinese Spring (CS) contains the long arm of the chromosome 7E from Thinopyrum elongatum (CS-7EL), which confers high resistance to fusarium head blight. It is of great interest to breeders to integrate the resistance locus (loci) from Th. elongatum into commercial wheat varieties. The objectives of this study were to identify candidate genes expressed from the 7EL chromosome of CS-7EL, to develop 7EL-specific molecular markers, and to validate their usefulness to characterize recombination between one of the group 7 chromosomes of wheat and Th. more...

(Submitter supplied) Salicylic acid (SA) is one of the key signal molecules in regulating plant resistance to diverse pathogens. It is predominantly associated with resistance against biotrophic and hemibiotrophic pathogens, and triggering systemic acquired resistance (SAR) in Arabidopsis. However, whether and how SA directly affects Fusarium graminearum and how SA influences the defence efficiency of wheat against fusarium head blight (FHB) are still poorly understood. more...

(Submitter supplied) In this study, we used dual RNA-sequencing to profile FHB-resistant AC Emerson, FHB-moderately AC Morley, and FHB-susceptible CDC Falcon winter wheat cultivars prior to and in response to Fusarium graminearum at 7 days post inoculation. Differential expression analyses revealed distinct defense responses between resistant and susceptible wheat cultivars including increased mechanical defense through lignin biosynthesis and increased deoxynivalenol (DON) detoxification through UDP-glycosyltransferase activity in resistant cultivars. more...

(Submitter supplied) In this study, a newly developed 8x15K Fusarium graminearum Agilent microarray was applied to analyze transcriptional responses to azole fungicide treatment. Comparative statistical analysis of expression profiles from treated versus untreated fungal liquid cultures uncovered 1058 genes that were significantly differentially expressed. Among the 596 genes with significantly increased transcript levels, analyses using GeneOntology and FunCat annotations detected the ergosterol-biosynthesis pathway genes as the most significantly responding category, providing statistical confirmation of the mode-of-action of azole fungicides. more...
