Expression data from elicitor-treated Arabidopsis seedling roots [25min]

ABSTRACT: Plants can perceive the presence of pathogens at the cell surface and plant damage-derived molecules via recognition of conserved microbial molecules, named pathogen- or microbe-associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs). Well-studied examples of PAMPs are chito-oligomers, breakdown products of fungal cell walls and insect exoskeletons. Pectin-derived oligogalacturonides (OGs) are well-characterized DAMPs. Both PAMPs nd DAMPs are capable of activating plant immunity, generating changes in gene expression that lead to increased production of defense compounds and proteins; thus, equipping the plant cell to defend itself. We used microarrays to assess the gene expression changes that follow 25min after elicitor treatment.

Comprehensive analysis of the membrane phosphoproteome regulated by oligogalacturonides in Arabidopsis thaliana

Project description:Early changes in the Arabidopsis thaliana membrane phosphoproteome in response to oligogalacturonides (OGs), a class of plant damage-associated molecular patterns (DAMPs), were analyzed through phosphopeptide enrichment followed by LC-MS/MS using label-free quantification. This large-scale phosphoproteome analysis of early OG-signaling enabled us to determine 100 regulated phosphosites.

Response of tobacco cells to Glucan elicitor

Project description:We have previously reported that the responses of tobacco tissues treated with AaGlucan are similar to those for laminarin [1]. To better understand the overall responses and signaling pathways in tobacco, we have identified here AaGlucan and laminarin early response genes, using a custom 16K BY-2 microarray [2,3]. BY-2 cells were treated with laminarin or an AaGlucan-enriched fraction prepared from A. alternata 102 culture-medium and subjected to microarray analysis.

Transcriptomic changes in macrophages induced by damage-associated molecular patterns (DAMPs)

Project description:Dead cell-derived molecules, typically called as damage-accociated molecular patterns (DAMPs), have been shown to evoke inflammatory responses. Accordingly, it becomes increasingly clear that DAMPs play important role in pathogenesis of multiple diseases including inflammatory diseases and cancer. To get a comprihensive view of DAMP-mediated inflammatory responses, we perfomed microarray analysis on murine macrophages treated by dead cell-derived molecules.

Prunus dulcis response to novel defense elicitor peptides and control of Xylella fastidiosa infections

Project description:Xylella fastidiosa is a plant pathogenic bacterium that has been introduced in the European Union (EU), threatening the agricultural economy of relevant Mediterranean crops such as almond (Prunus dulcis). Plant defense elicitor peptides would be promising to manage diseases such as almond leaf scorch but their effect on the host has not been fully studied. In this work, the response of almond plants to the defense elicitor peptide flg22-NH2 was studied in-depth using RNA-seq, confirming the activation of the salicylic acid and abscisic acid pathways. Marker genes related to the response triggered by flg22-NH2 were used to study the effect of the application strategy of the peptide on almond plants and to depict its time course. The application of flg22-NH2 by endotherapy triggered the highest number of upregulated genes, especially at 6 hours after the treatment. A library of peptides that include BP100-flg15, HpaG23, FV7, RIJK2, PIP-1, Pep13, BP16-Pep13, flg15-BP100 and BP16 triggered a stronger defense response in almond plants than flg22-NH2. The best candidate, FV7, when applied by endotherapy on almond plants inoculated with X. fastidiosa, significantly reduced levels of the pathogen and decreased disease symptoms. Therefore, these novel plant defense elicitors are suitable candidates to manage diseases caused by X. fastidiosa, in particular almond leaf scorch.
