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. Three biological replicates with leaves from 8 plants per sample were collected at 0 and 4 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: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).

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 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. Three biological replicates with leaves from 8 plants per sample were collected at 0, 4, 8, and 24 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). Equal amount of RNA from the 3 biological replicates were pooled 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 Experiment Overall Design: Each 3 leaves of plants of 5-week-old wild type Columbia-0 and mutant gh3.5-1D (heterozygous) were inoculated with Pst DC3000(avrRpt2)at 105 cfu mL-1. Leaves were harvested at 0 h (uninoculated) and 48 hours after inoculation. Three biological repeats were performed on Columbia-0 (wild-type, Col-0) and gh3.5-1D (mutant) after infection with or without Pst DC3000(avrRpt2), respectively.
