Transcriptome analysis of calcineurin-mediated genes in Fusarium oxysporum f. sp. lycopersici 4287

Project description:To further understand the abnormal phenotype of the calcineurin mutant strains and identify calcineurin-mediated genes in F. oxysporum f. sp. lycopersici, we performed RNA sequencing to compare the transcriptome profiles of the wild-type (WT), Δcna1(HFW1) and Δcnb1 (HFW3) mutants. By pairwise analysis, a total of 2139 genes were differentially expressed between WT and Δcna1 mutant based on the selection criteria of four-fold change in expression (Log2 fold change > 2 or < -2, P < 0.05). Among these, 1079 genes were upregulated and 1060 genes were downregulated. Moreover, from the comparison of WT against Δcnb1 mutant, 1412 gene were being regulated, and 840 genes were upregulated while 572 genes were downregulated. To elucidate genes that were regulated by calcineurin in F. oxysporum f. sp. lycopersici, the gene sets obtained from the pairwise analyses were compared, giving an overlap of 737 genes. Among these, 414 genes were found to be downregulated and 323 were upregulated, indicating that these genes possibly involved in the calcineurin pathway. GO functional analysis showed these transcripts were mainly involved in the oxidation-reduction process, single-organism metabolic process, transporter activity, cofactor binding, and other metabolic and biological processes.

Comparsion of histone modifications of core and accessory chromosomes of Fusarium oxysporum

Project description:To study whether there are differences in chromatin-mediated regulation between and within chromosomes in Fusarium oxysporum f. sp. lycopersici 4287 (FGSC9935), we determined the distribution of histone marks associated with euchromatin (H3K4me2) and facultative heterochromatin (H3K27me3) in vitro. We then determined whether these differences correlate with differences in dispensability and sequence divergence and gene expression.

Fusarium oxysporum f.sp. radicis-lycopersici induces distinct transcriptome reprogramming in resistant and susceptible isogenic tomato lines

Project description:Background: Fusarium oxysporum f.sp. radicis-lycopersici (FORL) is one of the most destructive necrotrophic pathogen of tomato, causing important field and greenhouse yield losses. Despite the relevant economic impact, little is known about the molecular mechanisms regulating the Fusarium oxysporum f.sp. radicis-lycopersici resistance in tomato. Results: A transcriptomic experiment was carried out in order to investigate major mechanisms of FORL response in resistant and susceptible isogenic tomato lines. The microarray analysis at 15 DPI reveals a distinct gene expression pattern between the two genotypes in the inoculated vs not inoculated conditions, furthermore confirmed by a q-PCR experiment. A model of plant response for both compatible and incompatible reaction was proposed. In particular, in the incompatible interaction an activation of defense genes related to secondary metabolites production and tryptophan metabolism was observed. Moreover, the cell osmotic potential maintenance after the FORL roots challenging was mediated by a dehydration induced protein. As for the compatible interaction the activation of an oxidative burst mediated by Peroxidases and a Cytochrome monooxigenase, conducedthe cells to degeneration and necrosis. Conclusions: Our work allowed a comprehensive understanding of the molecular basis of the tomato-FORL interaction. Result obtained emphasizes a different transcriptional reaction between the resistant and the susceptible genotype to FORL challenging. Our findings could lead to the improvement of strategies of this disease control.

TMT-based quantitative proteomic analysis of Fusarium oxysporum f. sp. radicis-lycopersici treated with linalool

Project description:Tandem Mass Tag (TMT)-based quantitative proteomic analysis of tomato soil borne pathogen Fusarium oxysporum f. sp. radicis-lycopersici growth, and metabolism when treated with plant natural volatile organic compounds linalool. The Forl strain was cultured on PDA supplied with 0.8 mL/L linalool for 6 days at 25°C. The fungal strain on PDA supplied with only 0.1% Tween80 was cultured as the control. Three biological replicates were established for each treatment.
