Background and Aims Fusarium crown rot caused by the fungal pathogen Fusarium pseudograminearum is a disease of wheat and barley, bearing significant economic cost. Efforts to develop effective resistance to this disease have been hampered by the quantitative nature of resistance and a lack of understanding of the factors associated with resistance and susceptibility. Here, we aimed to dissect transcriptional responses triggered in wheat by F. pseudograminearum infection. Methods We used an RNA…

Transcriptome analysis of Brachypodium during fungal pathogen infection reveals both shared and distinct defense responses with wheat
TLDR
Functional analyses of candidate genes identified in this study will improve the understanding of resistance mechanisms and may lead to the development of new strategies to protect cereal crops from pathogen infection.
Fusarium crown rot caused by Fusarium pseudograminearum in cereal crops: recent progress and future prospects.
TLDR
The sequencing and comparative analyses of the F. pseudograminearum genome have revealed novel virulence factors, possibly acquired through horizontal gene transfer, and a conserved pathogen gene cluster involved in the degradation of wheat defence compounds has been identified.
Expression of Fusarium pseudograminearum FpNPS9 in wheat plant and its function in pathogenicity
TLDR
The expression of FpNPS 9 which was significantly up regulated during the infection of wheat was determined and new knowledge on FnPS9 expression in F. pseudograminearum and its function was provided.
Comparing transcriptional responses to Fusarium crown rot in wheat and barley identified an important relationship between disease resistance and drought tolerance
TLDR
It is suggested that the resistant isoline in wheat was experiencing less drought stress, which could contribute to the stronger defence response than the sensitive isoline, and the possibility to enhance FCR resistance by manipulating genes conferring drought tolerance.
Transcriptomics of cereal-Fusarium graminearum interactions: what we have learned so far.
TLDR
An overview of how transcriptomic analyses employed to dissect host responses to DON have facilitated the identification of the genes involved in toxin detoxification and disease resistance and how such analyses have advanced understanding of this economically important plant-microbe interaction is presented.
TMT-based quantitative proteomic analysis reveals defense mechanism of wheat against the crown rot pathogen Fusarium pseudograminearum
TLDR
Insight is provided into the molecular mechanisms of the interaction between wheat and F. pseudograminearum as well as the morphological, physiological, and biochemical responses of the roots to disease differed between the two cultivars.
Taxonomically Restricted Wheat Genes Interact With Small Secreted Fungal Proteins and Enhance Resistance to Septoria Tritici Blotch Disease
Understanding the nuances of host/pathogen interactions are paramount if we wish to effectively control cereal diseases. In the case of the wheat/Zymoseptoria tritici interaction that leads to
Transcriptional profiling by RNA sequencing of black pepper (Piper nigrum L.) roots infected by Fusarium solani f. sp. piperis
TLDR
A global analysis of differentially expressed black pepper genes has demonstrated an enrichment of genes involved in proteolysis, plastid degradation, cell-wall remodeling and secondary metabolism, consistent with toxicity and necrotrophic fungal interactions that force plants to collaborate at the metabolic level.

Jasmonate and ethylene dependent defence gene expression and suppression of fungal virulence factors: two essential mechanisms of Fusarium head blight resistance in wheat?
TLDR
Especially ABC transporter, UDP-glucosyltransferase, protease and protease inhibitor genes associated with the defence mechanism against fungal virulence factors are apparently active in different resistant genetic backgrounds, according to reports on other wheat cultivars and barley.
Joint Transcriptomic and Metabolomic Analyses Reveal Changes in the Primary Metabolism and Imbalances in the Subgenome Orchestration in the Bread Wheat Molecular Response to Fusarium graminearum
TLDR
Transcriptomics and metabolomics data are integrated to dissect the molecular response to the fungus and its main virulence factor, the toxin deoxynivalenol in near-isogenic lines segregating for two resistance quantitative trait loci, Fhb1 and Qfhs, and identify several genes that may contribute to increased pathogen endurance.
Differential gene expression and metabolomic analyses of Brachypodium distachyon infected by deoxynivalenol producing and non-producing strains of Fusarium graminearum
TLDR
While the fungus uses DON as a virulence factor, the host plant preferentially induces detoxification and the phenylpropanoid and phenolamide pathways as resistance mechanisms, and Bd exhibits defense hallmarks similar to those already identified in cereal crops.
Phases of infection and gene expression of Fusarium graminearum during crown rot disease of wheat.
TLDR
Global comparisons of fungal gene expression with published data for FHB showed significant similarities between early stages of FHB and CR, indicating that CR disease development involves distinct phases of colonization, each of which is associated with a different fungalGene expression program.
Differential transcriptome analyses of three wheat genotypes reveal different host response pathways associated with Fusarium head blight and trichothecene resistance
TLDR
It is proposed that Type 1 resistance in one of the resistant double haploid lines evaluated here involves a combination of structural features that slow fungal penetration and activation of a systemic response in uninfected tissues adjacent to the site of infection to prevent or minimize secondary infection.
Transcriptome analysis of wheat inoculated with Fusarium graminearum
TLDR
This study presented new insights to understand the early response of selected cultivars to the Fg at 12 hai, and observed that the most altered transcripts were associated with starch and sucrose metabolism and gluconeogenesis pathways.
