Project description:The plant response may be triggered by various factors, including pathogens, non-pathogenic microbes, and natural or synthetic molecules, such as salicylic acid (SA), benzo(1,2,3)-Thiadiazole-7-Carbothioic Acid S-Methyl Ester (BTH) that are considered as plant resistance inducers. Resistance inducers mobilize the plant for the synthesis of defense compounds, but they are not directly toxic for the plant. The BTH is an analogue of SA, a molecule naturally synthesized in the plant during systemic acquired resistance (SAR). In this study, we hypothesized that challenging the plant with resistance inducer causes an increase in the level of proteins associated with defence response to external stimuli with primary metabolism and that the action of the choline derivative of the BTH (in the form of the ionic liquid) during induction of resistance in tomato plants is mediated by to some extent similar signaling pathways as it is in the case of unmodified BTH compound. Therefore, this study aimed to identify global proteome changes occurring in tomato plants exposed to resistance inducers as well as to identify common pathways associated with the plant's defense response to (+)ssRNA viruses induced upon both, viral infection and prior resistance inducer treatment. The effect of ionic liquids on changes in plant proteome is not described in the literature. The ionic character of compounds offers a great advantage of using them as the plant resistance inducer. The high chemical and thermal stability, as well as low volatility, guarantees safe application in fields. For that reason, comparing the action of the resistance inducer in the form of an ionic liquid with the core compound (BTH) will help to elucidate the mode of action of ionic liquid derivatives in plant resistance induction. To this end, two RNA-type viruses from different families were tested: tomato mosaic virus (ToMV, Virgaviridae) and potato virus Y (PVY, Potyviridae). The most affected processes presented in the results were: photosynthesis, regulation of oxidative stress, metabolism of glutathione and chitin, cell wall reorganization. The increased impact on the regulation of primary metabolism in inducer-treated plants (both for BTH and cholinium ionic liquid derivative). The response to ToMV and PVY was more intense when infected plants were pre-treated with inducers. The increased abundances of defense priming proteins with changes in cell wall organization may block virus transport from infected spots to other tissue of the host plant so that the losses caused by the disease will be lower.

Project description:Powdery mildew, caused by the fungus Blumeria graminis (DC) Speer, is one of the most important foliar diseases of cereals worldwide. It is an obligate biotrophic parasite, colonising leaf epidermal cells to obtain nutrients from the plant cells without killing them. Syringolin A (sylA), a circular peptide secreted by the phytopathogenic bacterium Pseudomonas syringae pv. syringae, triggers a hypersensitive cell death reaction (HR) at infection sites when sprayed onto powdery mildew infected wheat which essentially eradicates the fungus. The rational was to identify genes whose expression was specifically regulated during HR, i.e. genes that might be involved in the switch of compatibility to incompatibility.<br>Powdery mildew-infected or uninfected plants were treated with syringolin two days after infection and plant material for RNA extraction was collected at 0.5, 1, 2, 4, 8, 12 hours after treatment (hat), resulting in an early (2 and 4 hat) and late pool (8 and 12 hat). Plant material that was uninfected prior to syringolin treatment was collected 8 and 12 hat (late pool of uninfected plant material), and 1 hat, respectively.

Project description:NPR1 is a central positive regulator of salicylic-acid (SA)-mediated defense signaling in Arabidopsis. Here, we report characterization of OsNPR1, an Oryzae sativa (rice) ortholog of NPR1, focusing on its role in blast disease resistance and identification of OsNPR1-regulated genes followed by their comparison with NPR1-regulated genes in Arabidopsis. Blast resistance tests using OsNPR1–knockdown and –overexpressing rice lines indicated that OsNPR1 plays an essential role in benzothiadiazole-induced blast resistance. Genome-wide transcript profiling using OsNPR1–knockdown lines revealed that 358 genes out of 1,228 BTH-upregulated genes and 724 genes out of 1,069 BTH-downregulated genes were OsNPR1 dependent with respect to their BTH responsiveness, indicating that OsNPR1 plays a major role in the downregulation. Inspection of OsNPR1-dependent genes revealed that many genes involved in photosynthesis and chloroplastic translation and transcription were downregulated by BTH in an OsNPR1 dependent manner, indicating that photosynthesis and chloroplast activities is coordinately suppressed by OsNPR1 in response to BTH-induced activation of SA-signaling pathway. ABA-responsive genes were also OsNPR1-dependently downregulated, suggesting antagonistic interaction of SA signaling on ABA signaling. None of 11 BTH-upregulated genes for WRKY transcription factors was OsNPR1 dependent, whereas most of those are NPR1-dependently upregulated in Arabidopsis, indicating that the role of OsNPR1 is distinct from that of NPR1 in Arabidopsis. We discuss the significance of OsNPR1-regulated gene expression in SA-regulated defense program and the role of OsNPR1 in rice SA-signaling pathway that is branched to OsNPR1- and rice WRKY45-dependent sub-pathways. mock-treated wild-type (Nipponbare) rice, benzothiadiazole (BTH)-treated wild-type rice, mock-treated WRKY45-knockdown rice (2 lines) and BTH-treated WRKY45-knockdown rice (2 lines) were analyzed in four biological replicates.
