Project description:Identification of AvrRpt2-mediated differential gene expression in Arabidopsis Four-week-old leaves of Arabidopsis Col-0 plant were infiltrated with Pseudomonas syringae pv. Maculicola carring effector AvrRpt2 at OD0.01. Samples were collected at 0 or 6 hours after infiltration. Each time point contains three biological replicates.
Project description:Identification of differential gene expression during RPS2-mediated effector-triggered immunity in Arabidopsis Four-week-old leaves of Arabidopsis Col-0 wild type and rps2 mutant plant were infiltrated with Pseudomonas syringae pv. Maculicola carring effector AvrRpt2 at OD 0.01. Samples were collected at 0, 6 and 10 hours after infiltration for WT plants and at 0 and 10 hours after infiltration for rps2 plants. Three biological replicates were performed per genotype per time point.
Project description:The goal of the microarray experiment was to determine the induction kinetics of transcriptome changes in the Arabidopsis mutant Atelp2, npr1 and wild type in response to infection of the avirulent bacterial pathogen Pst DC3000/avrRpt2. Results indicated that Atelp2 exhibited slower kinetcis of transcriptional changes than the wild type after Pst DC3000/avrRpt2 infection, whereas npr1 did not show significant alteration in the induction kinetics.
Project description:The goal of the microarray experiment was to determine the induction kinetics of transcriptome changes and to identify differentially expressed genes in the Arabidopsis mutant med14 and wild type in response to infection of the avirulent bacterial pathogen Pst DC3000/avrRpt2. Results indicated that med14 exhibited slower kinetcis of transcriptional changes than the wild type after Pst DC3000/avrRpt2 infection, and the induction of a large group of defense genes was suppressed in the med14 mutant.
Project description:The goal of the microarray experiment was to identify genes that are differentially expressed among the Arabidopsis mutant med14, med16, npr1, and wild type in response to infection of the avirulent bacterial pathogen Pst DC3000/avrRpt2. Results indicated that the induction of a large group of defense genes was suppressed in the med14 mutant compared with both med16 and the wild type.
Project description:The goal of the microarray experiment was to identify defense genes that were differentially expressed in the Arabidopsis mutant At-med16-1 and wild type in response to infection of the avirulent bacterial pathogen Pst DC3000/avrRpt2. Results indicated that, compared with the wild type, several positive regulators of SAR (systemic acquired resistance) were downregulated and a group of SAR negative regulators were upregulated in At-med16-1.
Project description:The goal of the microarray experiment was to determine the induction kinetics of transcriptome changes and to identify differentially expressed genes in the Arabidopsis mutant med14 and wild type in response to infection of the avirulent bacterial pathogen Pst DC3000/avrRpt2. Results indicated that med14 exhibited slower kinetcis of transcriptional changes than the wild type after Pst DC3000/avrRpt2 infection, and the induction of a large group of defense genes was suppressed in the med14 mutant. Three biological replicates with leaves from 8 plants per sample were collected at 0, 4, 8, and 12 hours after inoculation with the avirulent bacterial pathogen Pst DC3000/avrRpt2. After extraction, RNA concentration was determined on a NanoDrop Spectrophotometer (Thermofisher Scientific, Waltham, MA) and sample quality was assessed using the 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA). Each replicate was used as one sample for microarray analysis.

Project description:To reveal the underlying molecular mechanism of GH3.5 action in modulating the SA and auxin pathways, we performed transcriptional profiling of gh3.5-1D plants after infection with or without Pst DC3000(avrRpt2) on a global scale using the Affymetrix Arabidopsis ATH1 GeneChip Keywords: Pathogen-response
