Gene expression profiling of early events of DSF elicitor based defense signalling in Arabidopsis thaliana

ABSTRACT: To study the early events of priming response leading to changes in gene expression in Arabidopsis thaliana Col0 wild type plant on infiltration with the potent elicitor molecule Diffusible Signal Factor (DSF). In the present experimentation we have employed total RNA microarray expression profiling as a discovery platform to identify differentially expressing genes that are upregulated and down regulated in the various pathways involved in priming the defense responses by the elicitor molecule DSF on infiltration in the host plant Arabidopsis thaliana. This would help understand the possible defense pathways elicited by the elicitor molecule during interaction. The rosette leaves of Arabidopsis thaliana Col0 plants of 4 weeks old were infiltrated with 100uM DSF and the total RNA samples at 4hpi, 8hpi and 16hpi were extracted along with methanol treatment serving as a control in two biological replicates 1A and 2A. Further, these RNA samples were checked for the quality and subjected to microarray analysis. The differentially expressing candidate genes were identified specific to DSF treatment and were quantified by real-time PCR post DSF treatments.

DSF effects on Arabidopsis

Project description:To investigate the effects of DSF on Arabidopsis in Xcc infecction, we used 2 μM DSF pretreated the roos of Arabidopsis for 48h and then inoculated with Xcc, We then performed gene expression profiling analysis using data obtained from RNA-seq of pretreated/unpretreated at two time points (inoculated with Xcc or not)

Transcriptome changes triggered by the synthetic defense elicitors DCA and INA in Arabidopsis thaliana

Project description:DCA (3,5-Dichloroanthranilic acid) is a newly identified synthetic defense elicitor. To perform a comparative analysis of defense responses triggered by DCA and the structurally related defense inducer INA (2,6-Dichloroisonicotinic acid) Affymetrix chip experiments were performed with Arabidopsis thaliana seedlings treated with one of these two compounds.

Arabidopsis thaliana gene expression changes upon treatment with green peach aphid saliva

Project description:Myzus persicae (green peach aphid) feeding on Arabidopsis thaliana induces a defense response, quantified as reduced aphid progeny production, in infested leaves but not in other parts of the plant. Similarly, infiltration of aphid saliva into Arabidopsis leaves causes only a local increase in aphid resistance. Further characterization of the defense-eliciting salivary components indicates that Arabidopsis recognizes a proteinaceous elicitor with a size between 3 to 10 kD. Genetic analysis using well-characterized Arabidopsis mutant shows that saliva-induced resistance against M. persicae is independent of the known defense signaling pathways involving salicylic acid, jasmonate, and ethylene. Among 78 Arabidopsis genes that were induced by aphid saliva infiltration, 52 had been identified previously as aphid-induced, but few are responsive to the well-known plant defense signaling molecules salicylic acid and jasmonate. Quantitative PCR analysis confirms expression of saliva-induced genes. In particular, expression of a set of O-methyltransferases, which may be involved in the synthesis of aphid-repellent glucosinolates, was significantly up-regulated by both M. persicae feeding and treatment with aphid saliva. However, this did not correlate with increased production of 4-methoxyindol-3-ylmethylglucosinolate, suggesting that aphid salivary components trigger an Arabidopsis defense response that is independent of this aphid-deterrent glucosinolate. Experiment Overall Design: 3 biological replicates (control and treatment). Total number of samples: 6.

Expression data from volatile treated and insect damaged Arabidopsis thaliana

Project description:Plant volatiles can mediate plant-plant communication in the sense that plants attacked by herbivores can signal their unattacked neighbors of danger by emitting HIPVs. We call this the priming effect. Since the plant defense response is a systematic process involving numerous pathways and genes,to characterize the priming process, a time course study using a genome-wide microarray may provide more accurate information about the priming process. Furthermore, to what extent do the priming process and direct defense share similar gene expression profiles or pathways are also not clear. We used microarray to detect the priming effect of plant volatiles to healthy Arabidopsis thaliana, and the effect of direct leafminer feeding to Arabidopsis thalianas. A system using Lima bean plants, from which HIPVs can be effectively induced by leafminer feeding, as emitters and Arabidopsis thaliana as receivers is used to track the priming process between neighbor plants. The Arabisopsis thaliana seedlings were treated by volatiles from leafminer fed lima bean for 24h or 48h for RNA extraction and hybridization on Affymetrix microarrays. The Arabisopsis thaliana seedlings fed by leafminer directly were also collected The for RNA extraction and hybridization on Affymetrix micorarrays. We want to explore the response of Arabidopsis thaliana to priming volatiles during a 24h-48h time course. We also want to compare the effect of priming and direct leafminer feeding.
