(Submitter supplied) 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.

(Submitter supplied) The goal of the microarray was to investigate the transcriptome changes induced by exogenous NAD+ in the wild-type Col-0 plants. Results showed that exogenous NAD+-induced dramatic transcriptional changes in Arabidopsis. Particularly, a large group of salicylic acid pathway genes including NPR1 and its traget genes were induced by NAD+, whereas the jasmonic acid/ethylene pathway defense marker gene PDF1.2 was inhibited by NAD+ treatment. more...

(Submitter supplied) The goal of the microarray was to compare the bacterial pathogen Pseudomonas syringae pv. maculicola ES4326 (Psm)-induced transcriptome changes in the systemic leaves of the wild-type Col-0, lecrk-VI.2-2, and bak1-5 plants. Results showed that local Psm inoculation induced dramatic transcriptional changes in Col-0, with 564 and 151 genes up- and down-regulated at least twofold with a low q value (≤ 0.05), respectively. more...

(Submitter supplied) The goal of the microarray experiment was to identify defense genes that were differentially expressed in the Arabidopsis mutant elp2 and wild type in response to infection of the necrotrophic fungal pathogen Botrytis cinerea. Results indicated that, compared with the wild type, the WRKY33/OCTADECANOID-RESPONSIVE ARABIDOPSIS AP2/ERF59 (ORA59)/ETHYLENE RESPONSE FACTOR1 transcriptional cascades are down-regulated, whereas the MYC2 transcriptional cascade is up-regulated in the elp2 mutant.

(Submitter supplied) 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.

(Submitter supplied) Systemic acquired resistance (SAR) is a long-lasting broad-spectrum plant defense mechanism that is induced by mobile signals generated in the primarily infected leaves. Although multiple mobile SAR signals have been proposed, how these signals are perceived in the systemic leaves is unknown. Here, we show that extracellular nicotinamide adenine dinucleotide (phosphate) (eNAD(P)) accumulates in the systemic leaves and that both eNAD(P) and its receptor, the lectin receptor kinase (LecRK), LecRK-VI.2, are required in the systemic leaves for the establishment of SAR. more...

(Submitter supplied) 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.

(Submitter supplied) Arabidopsis Enhanced Disease Susceptibility 1 (EDS1) and its direct partner Phytoalexin Deficient 4 (PAD4) are required for both basal resistance against virulent pathogens and innate immune responses mediated by all tested TIR (Toll-Interleukin-1 Receptors) type nucleotide-binding/leucine-rich-repeat (NLR) receptors. Using transgenic Arabidopsis plants in Col-0 eds1-2 pad4-1 background conditionally expressing PAD4 and constitutively expressing EDS1 (ED-P4E1), an EDS1/PAD4 immune response can be triggered by estradiol treatment and can induce expression of defense-related genes and lead to enhanced basal resistance. more...

(Submitter supplied) The modification of histones by acetyl groups has a key role in the regulation of chromatin structure and transcription. The Arabidopsis thaliana histone acetyltransferase GCN5 regulates histone modifications as part of the Spt-Ada-Gcn5 Acetyltransferase (SAGA) transcriptional coactivator complex. GCN5 was previously shown to acetylate lysine 14 of histone 3 (H3K14ac) in the promoter regions of its target genes; however, its binding did not systematically correlate with gene activation and the mechanism by which GCN5 controls transcription thus remained unclear. more...

(Submitter supplied) Genome-wide direct targets of Arabidopsis NPR1 and HAC1 were identified by chromain immunoprecipitation followed by sequencing (ChIP-seq). For the study, we used Arabidopsis expressing NPR1:GFP or HAC1:mCherry under native NPR1 or HAC1 promoter, respectively. To identify direct targets both under salicylic acid-treated and untreated conditions, we performed ChIP-seq by using 2,6-dichloroisonicotinc acid (INA; synthetic SA analog)-treated and untreated NPR1:GFP or HAC1:mCherry transgenic Arabidopsis plants.
