Dual RNA-sequencing of Fusarium Head Blight resistance in winter wheat

ABSTRACT: 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. Further, differential expression analysis in F. graminearum challenging these distinct cultivars revealed changes genes involved in trichothecene mycotoxin biosynthesis.

Molecular pathogenetic study of Fusarium head blight in highly resistant, resistant and susceptible common wheat (Triticum aestivum L.)

Project description:Fusarium graminearum (F.g) is responsible for Fusarium head blight (FHB), which is a destructive disease of wheat that accumulates mycotoxin such as deoxynivalenol (DON) and makes its quality unsuitable for end use. Several FHB resistant varieties development is going on world-wide. However the complete understanding of wheat defence response, pathogen (Fusarium graminearum) disease development mechanism and the gene crosstalk between organisms is still unclear. In our study focused to analyse pathogen (F. graminearum) molecular action in different Fusarium head blight resistance cultivars during the disease development. To understand the Fusarium graminearum pathogen molecular reaction, microarray gene expression analysis was carried out by using Fusarium graminearum (8 x 15k) Agilent arrays at two time points (3 & 7 days after infection) on three wheat genotypes (Japanese landrace cv. Nobeokabouzu-komugi - highly resistant, Chinese cv. Sumai 3 - resistant and Australian cv. Gamenya - susceptible), which spikes infected by Fusarium graminearum ‘H-3’strain. During the disease development the pathogen biomass as well as the expression of Trichothecene biosynthesis involved genes (Tri genes) in three wheat cultivars was determined. In our material no relation between fungus biomass and the disease symptoms were observed, however, it showed relation with fungus virulence factors expression (Tri genes). For the first time, we report the nature of Fusarium graminearum gene expression in the FHB-highly resistant cv. Nobeokabouzu-komugi during the disease development stage and the possible underlying molecular response.

Global gene expression analysis of FHB disease spreading mechanism in wheat

Project description:The Fusarium graminearum is responsible for Fusarium head blight (FHB) disease in wheat which makes unsuitable for end-use quality of wheat. For that reason several studies have been aiming to develop FHB resistant cultivars. In order to clarify possible wheat response mechanism, global gene expression analysis in response to the pathogen was undertaken. The study was conducted using three genotype of wheat, Japanese cultivar Nobeokabouzu-komugi (Highly resistant), cv. Sumai 3 (Resistant) and cv. Gamenya (Susceptible) which florets were inoculated Fusarium graminearum M-bM-^@M-^\H-3M-bM-^@M-^] strain during the flowering stage. For microarray analysis used samples of 3 and 7 days after inoculation (DAI) and Agilent wheat custom array 4x38k. Over 1400 genes were differentially up-regulated in Nobeokabouzu-komugi at 3 DAI followed by Sumai 3 and minimum expression in Gamenya, whereas at 7 DAI in Sumai 3 observed high expression and minimum in Gamenya. Further narrowing down by removing commonly expressed genes in three genotypes and grouping according to the gene function, identified differentially high expression of genes involved in detoxification process such as multidrug resistant rpoteins, UDP-glycosyltransferase and ABC transporters in Nobeokabouzu-komugi at 3 DAI. However in Sumai 3 found many localized defense-related genes such as peroxidase, proteases and genes involved in plant cell wall defense at 7 DAI. Following in silico analysis, revealed those genes were located in different chromosomes. This finding showed the differentiation of molecular response mechanism among the FHB resistant cultivars in response to the pathogen. F. graminearum inoculated (3 and 7 days after inoculation) and water inoculated Mock samples were used for cRNA synthesis and further hybridization with 3 biological replications. Total 12 samples per genotype

Transcriptome analysis of a wheat NIL pair carrying FHB resistant and susceptible alleles

Project description: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. graminearum infection; and (4) to examine the relationship between transcript accumulation, disease severity, fungal biomass and trichothecene accumulation in wheat. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Seungho Cho. The equivalent experiment is TA20 at PLEXdb.] FHB resistant and susceptible plants 48 an 96 hours after treatment with Fusarium graminearum strain Butte 86

Transcription profiling of Fusarium head blight resistance in Sumai-3 and two susceptible NILs

Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.

Differential transcriptome analysis of two wheat genotypes in their response to Fusarium head blight

Project description:Fusarium Head Blight (FHB) is a disease of wheat and other cereal crops, where, among other species, Fusarium graminearum infects the wheat inflorescence. Microarrays were used to observe differential gene expression in FHB-challenged spikes of the two European winter wheat genotypes Dream (moderately resistant) and Lynx (susceptible). Plants were either inoculated with the Fusarium graminearum strain IFA 65 (IFA Tulln) (500 macroconidia/floret) or were as control plants mock treated with desalted water. The inocula were injected into four spikelets at early anthesis and spikelets were later on collected at 32 and 72 h after inoculation. Four plants were sampled per genotype/treatment/sampling date. Total RNA was extracted from collected spikelets, and microarray analysis was performed using the Affymetrix Wheat GeneChip.

Proteomics-based data integration of wheat cultivars facing Fusarium graminearum strains revealed a core-responsive pattern driving the fate of the interaction

Project description:The aim of this work is to dissect the plant component of the dual-proteome established during the FHB process using the same three wheat cultivars facing the three fungal strains as described in Fabre et al. (2019b). Qualitative and quantitative dissection of the three wheat cultivar proteomes was devoted to identify molecular events that drive the FHB-susceptibility differences. This included, the identification of (i) the generic molecular adjustments taking place during FHB progress, (ii) the cultivar-specific responses and their accommodation with different F. graminearum strains inducing FHB and (iii) the range of wheat proteins that basically discriminate the three wheat cultivars of contrasted susceptibility. The joint analysis of all these data with the fungal protein information was carried out to identify relationship between wheat protein abundance changes and fungal effectors differentially accumulated between the three F. graminearum strains (Fabre et al., 2019b).

Transcriptomic analysis of F. graminearum disease response in near-isogenic resistant and susceptible hexaploid wheat lines

Project description:Fusarium graminearum causes Fusarium head blight (FHB), which represents one of the major wheat diseases worldwide, determining reduction in grain quality, yield and the accumulation of mycotoxins. To mine the molecular response associated to the wheat 2DL FHB resistance quantitative trait locus (QTL), derived from the cultivar Wuhan-1, and to identify candidate genes implicated in such resistance, a comprehensive transcriptomic analysis of the early response to F. graminearum infection at 3 days post inoculation of spikelet and rachis was performed with the RNA-Seq and miRNA-Seq techniques. The analyses were conducted on two Near Isogenic Lines (NILs) differing for the presence of the 2DL QTL (2-2618, resistant 2DL+ and 2-2890, susceptible null).
