Project description:In order to better understand the transcriptional networks triggered by pathogen inoculation, we monitored gene expression in leaves of mutant Arabidopsis plants, inoculated with Pseudomonas syringae ES4326 and wild type Col-0 plants grown in parallel. Individual leaves were injected in the morning using a needle-less syringe with 10E5 cfu cm-2 PsmES4326 (suspended in 5 mM MgSO4). For the wild type, leaves were also mock treated with 5 mM MgSO4. Leaves were harvested 24 hours later. Plants were grown in pots with BM-2 soil (Berger Peat Moss Ltd, Quebec, Canada) at a density of 9 plants per pot and kept at 22 degrees Celsius with 75% humidity and a 12 hour day length.

Project description:0.5 mM SA plus 0.02% Silwet or 0.02% Silwet (control) was sprayed on leaves of 3.5 week old Arabidopsis plants. Samples were harvested at 0 (prior to treatment) , 3, 6, 12, and 24 hours post treatment. A subset of these samples were processed.

Project description:0.5 mM SA plus 0.02% Silwet or 0.02% Silwet (control) was sprayed on leaves of 3.5 week old Arabidopsis plants. Samples were harvested at 0 (prior to treatment) , 3, 6, 12, and 24 hours post treatment. A subset of these samples were processed. Arabidopsis plants grown in parallel under standardized conditions were treated with SA + Silwet or Silwet alone (control). Only mature leaves of the same developmental age were harvested using leaves from 2-4 plants, totalling ~0.2 grams per sample. Plants were not resampled. In our hands, experimental replicates are highly reproducible. This was an exploratory experiment to look for candidate genes impacted by exogenous SA treatment. We were only able to process a subset of samples and chose to process key time points, sacrificing replicates at each time point.

Project description:Arabidopsis thaliana and Arabidopsis lyrata are two closely related Brassicaceae species, which are used as models for plant comparative biology. They differ by lifestyle, predominant mating strategy, ecological niches and genome organization. To identify heat stress induced genes, we performed RNA-sequencing of rosette leaves from mock-treated, heat-stressed and heat-stressed-recoved plants of both species.

Project description:Arabidopsis plants, ecotype Columbia, were sprayed with surfactant alone (0.01% Silwet) or surfactant and 1mM salicylic acid until all leaves were wet, 3 to 4 weeks after germination (before flowering). Leaves were harvested and frozen in liquid nitrogen. Three biological replicates were obtained over a period of 6 months. For each replicate, RNA was extracted using standard phenol/chloroform protocol and biotin-labeled cRNA was synthesized. cRNA was hybridized to 6 ATH1 GeneChip arrays. Cel files produced by the Affymetrix software were imported into R. Background subtraction, normalization and probe summaries were performed with the rma, quantile.normalization and median polish options of the rma function. Comparison of the SA- versus mock-treated tissue provides insight on the genes involved in systemic acquired resistance in Arabidopsis. Experiment Overall Design: 3 mock-treated and 3 SA-treated biological replicates were analyzed (one array each)

Project description:We investigated the relationships of the two immune-regulatory plant metabolites salicylic acid (SA) and pipecolic acid (Pip) in the establishment of plant systemic acquired resistance (SAR) in Arabidopsis thaliana induced by the bacterial pathogen Pseudomonas syringae. To characterize the transcriptional SAR response, we used wild-type Col-0 plants, SA-deficient sid2 plants and Pip-deficient ald1 plants and performed RNA-sequencing analyses (Bernsdorff et al., Plant Cell, 2016). SAR establishment in the wild-type is characterized by a strong transcriptional response systemically induced in the foliage that prepares plants for future pathogen attack by pre-activating multiple stages of defense signaling. Whereas systemic Pip elevations are indispensable for SAR and necessary for virtually the whole transcriptional SAR response, a moderate but significant SA-independent component of SAR activation and SAR gene expression is revealed. Arabidopsis thaliana plants were grown individually in pots containing a mixture of soil, vermiculite and sand (8:1:1) in a controlled cultivation chamber with a 10-h day (9 AM to 7 PM; photon flux density 100 mol m-2 s-1) / 14-h night cycle and a relative humidity of 70 %. Day and night temperatures were set to 21C and 18C, respectively. Experiments were performed with 5- to 6-week-old, naive plants exhibiting a uniform appearance. To activate SAR, plants were infiltrated between 10 AM and 12 AM into three lower (1) leaves with suspensions of the bacterial pathogen Pseudomonas syringae pv. maculicola (OD600 = 0.005). Infiltration with 10 mM MgCl2 served as the mock-control treatment. Upper (2) leaves were harvested 48 h after the primary treatment for the determination of systemic gene expression by RNA-seq analyses. Three biologically independent, replicate SAR induction experiments were performed with Col-0 and sid2 plants (experimental set 1), and three other biologically independent experiments with Col-0 and ald1 plants (experimental set 2). In each SAR experiment, at least 6 upper (2) leaves from 6 different plants pre-treated in 1 leaves with Psm (MgCl2) were pooled for one biological Psm- (mock-control) replicate. In this way, 3 biologically independent, replicate samples per treatment and plant genotype were obtained within each SAR set.
