RNAseq of roots and leaves of tender wheat (Triticum aestivum cv chinese Spring) during interactions with mycorhizal fungi (Funneliformis mossae) with and without a pathogen attack by Xanthomonas translucens

Project description:We monitored by RNAseq the transcriptomic response of roots and leaves of Triticum aestivum cv chinese Spring during a long term interaction with Funneliformis mossae (2 months) with or without a pathogen infection by infiltration of Xanthomonas translucens CFBP 2054. The control condition of roots and leaves wheat without mycorhizal fungi is in E-MTAB-5891 (material produced simultaneously and treated at the same time).

RNA-seq of wheat leaves and roots in response to Xanthomonas translucens infection

Project description:This study aimed at decrypting the transcriptomic response of 2 months-old grown tender wheat (cv Chinese Spring) to a the Xanthomonas translucens pathogen infection by infiltration. The response was monitored by RNAseq 24h post leaf clipping. Triticum aestivum cv. Chinese Spring plants were maintained in a growth chamber with cycles of 12 h of light at 21C and 50% relative humidity (RH) and 12 h of dark at 21C and 50% RH. Leaves of 49 days-old plants were infiltrated with a bacterial suspension in water with an optical density at 600 nm (OD600) of 0.5 using a needleless syringe. Plants inoculated with water were used as controls. For transcriptomic and proteomic analyses, leaves and root tissues were harvested 1 day post-inoculation (dpi), when symptoms were not visible yet. Three biological replicates per treatment were performed, and each with pooled leaves from two independent plants per replicate. The files per conditions and replicates are:Sample 1 Root tissue with 3 replicates: CONTROL * control condition for roots (wheat without pathogen infection): 3 replicates: 1.1R,1.2R, 1.3R * control condition for leaves (wheat without pathogen infection): 3 replicates1.1L,1.2L, 1.3L * Wheat Roots infected by Xanthomonas translucens: 3 replicates: 5.1R, 5.2R, 5.3R * Wheat Leaves infected by Xanthomonas translucens: 3 replicates: 5.1L, 5.2L, 5.3L

Transcriptome and proteome analysis reveals new insight into the proximal and distal responses of wheat to foliar infection by Xanthomonas translucens

Project description:The molecular details of local plant response against Xanthomonas translucens infection is largely unknown. Moreover, there is no knowledge about effects of the pathogen on the root’s transcriptome and proteome. Therefore, we investigated the global gene and protein expression changes both in leaves and roots of wheat (Triticum aestivum) 24h post leaf infection of X. translucens. This simultaneous analysis allowed us to obtain insight into possible metabolic rearrangements in above- and belowground tissues and to identify common responses as well as specific alterations. At the site of infection, we observed the implication of various components of the recognition, signaling, and amplification mechanisms in plant response to the pathogen. Moreover, data indicate a massive down-regulation of photosynthesis and confirm the chloroplast as crucial signaling hub during pathogen attack. Notably, roots responded as well to foliar attack and their response significantly differed from that locally triggered in infected leaves. Data indicate that roots as a site of energy production and synthesis of various secondary metabolites may actively influence the composition and colonisation level of root-associated microbes. Finally, our results emphasize the accumulation of jasmonic acid, pipecolic acid and/or the downstream mediator of hydrogen peroxide as long distal signals from infected leaves to roots.

Transcriptional profiling of sweet orange leaves infected with Xanthomonas citri and Xanthomonas aurantifolii pathotype C

Project description:To compare the early transcriptional changes that occur in sweet orange leaves in response to Xanthomonas citri versus Xanthomonas aurantifolii pathotype C infection, plant leaves infiltrated with each bacterial pathogen were examined by RNAseq.

Transcription profiling by array of wheat cultivars Flame and Longbow responce to Mycosphaerella graminicola

Project description:Mycosphaerella graminicola is the causal agent of Mycosphaerella graminicola infection (STB) disease of wheat. Wheat genotypes vary in their response to this disease. Cultivar (cv.) Longbow is susceptible and cv. Flame is resistant to STB disease, with cv. Flame possessing the STB resistance locus Stb6 that confers resistance to pathogen strain IPO323. Gene expression profiling (conducted using Affymetrix wheat gene chip) identified transcripts that accumulate in leaves of both these wheat cultivars as an early response to M. graminicola strain IPO323 (at 24h post-treatment). At this initial time point, microscopic analysis verified that fungal spores had germinated, but not penetrated the leaves of both genotypes. Results showed that basal defence genes were activated in both the compatible and incompatible interactions. A subset of genes were identified that were more pathogen-responsive in the cv. Flame v. IPO323 incompatible interaction as compared to the cv. Longbow v. IPO323 compatible interaction, including defence genes such as peroxidases, beta-1,3-glucanase, annexin, chitinases, brassinosteroid-associated kinase 1 and a jasmonate-inducible protein.

Transcription profiling of wild type and TaPrx103 over-expressing wheat plants subjected to pathogen attack by Blumeria graminis f.sp. tritici

Project description:Transgenic wheat plants of cv. Bobwhite were generated that constitutively overexpress class III peroxidase cDNA TaPrx103 (previously TaPERO) under the control of the epidermis-specific GstA1 promoter. Several transgenic lines show enhanced pathogen resistance. In order to test the concept of substantial equivalence, wildtype and transgenic lines were subjected to pathogen attack by Blumeria graminis f.sp. tritici, followed by transcript profiling using the barleyPGRC1 cDNA array.

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.
