Project description:Arabidopsis thaliana (Col-0) plants were treated with BABA and gene expression differences to control plants were monitored after dip-inoculation with Pseudomonas syringae pv tomato DC3000. Keywords: transcript profiling, response to BABA-induced priming and infection
Project description:This study investigates extent and functional significance of alternative splicing in Arabidopsis thaliana defense against the bacterial pathogen Pseudomonas syringae pv tomato (Pst). We have provided a detailed characterization of the Arabidopsis thaliana transcriptional response to Pseudomonas syringae infection in both susceptible and resistant hosts. We carried out two independent inoculation experiments (biological replicates) for each treatment. Col-0 is susceptible to virulent Pst DC3000 but has a functional RPS4 resistance gene effective against DC3000 expressing AvrRps4
Project description:The amino acid cysteine was repeatedly shown to be implicated in the plants stress response. This project aims to elucidate which effect cysteine has on the proteome of Arabidopsis. Treatment of Arabidopsis thaliana seedling cultures with cysteine resulted in distinct proteomic changes. To further investigate on the role of cysteine metabolism and associated proteins during biotic stress, the proteomic response of Arabidopsis thaliana leaves inoculated with the plant pathogen Pseudomonas syringae pv. tomato DC3000 was monitored.
Project description:The Arabidopsis Pathoarray 464_001 (GPL3638) was used to compare response of Col-0, pad4-1 (Zhou et al., 1998; Jirage et al., 1999) and sid2-2 (Wildermuth et al., 2001) to Pseudomonas syringae pv. tomato DC3000 hrcC mutant. SA production is drastically reduced in sid2 mutants. PAD4 is required for SA-mediated responses. The results suggested that the SA increase triggered by MAMPs is one major component in the MAMPs-triggered signaling mechanism. Keywords: Responses of Arabidopsis to Pseudomonas syringae pv. tomato DC3000 hrcC mutant
Project description:To characterize the PTI response of tomato and the effect of the delivery of a subset of effectors, we performed an RNA-seq analysis of tomato Rio Grande prf3 leaves challenged with either the flgII-28 peptide or the following bacterial strains: Agrobacterium tumefaciens GV2260, Pseudomonas fluorescens 55, Pseudomonas putida KT2440, Pseudomonas syringae pv. tomato (Pst) DC3000, Pst DC3000 deltahrcQ-U deltafliC and Pst DC3000 deltaavrPto deltaavrPtoB. NOTE: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Project description:Arabidopsis thaliana (Col-0) plants were treated with BABA and gene expression differences to control plants were monitored after dip-inoculation with Pseudomonas syringae pv tomato DC3000. Keywords: transcript profiling, response to BABA-induced priming and infection 3 independant replicates were analyzed by two color co-hybridizations. Leaf RNA from Pseudomonas infected control plants (Cy3 labeled cDNA) was cohybridized with leaf RNA from Pseudomonas infected BABA pretreated plants (Cy5 labeled cDNA). Samples were collected 22 hours after bacterial inoculation. BABA pretreatment was performed two days before bacterial inoculation. To assess the effect of BABA alone on gene expression, leaf RNA from BABA treated plants (Cy5 labeled cDNA) was cohybridized with leaf RNA (Cy3 labeled cDNA) from water treated plants.
Project description:Transcription profiling of Nicotinan benthamiana in response to Pectobacterium carotovorum WPP14 and Pseudomonas syringae pv. tomato DC3000
Project description:Time-course RNA-seq analysis of Arabidopsis thaliana Col-0 seedlings infected with Pseudomonas syringae pv. tomato DC3000 carrying effector genes AvrRpt2 or AvrRps4. Samples were collected at 6, 12, and 20 hours post-inoculation using a transient pathogen flood assay following Ishiga et al., 2011. This study aims to characterise the temporal dynamics of plant immune responses and identify transcriptional changes associated with effector-triggered immunity.
