Expression data from leafminer-damaged Arabidopsis thaliana

Project description:Plants have developed a complicated resistance system, and they exhibit various defense patterns in response to different attackers. However, the determine factors of plant defense patterns are still not clear. Here, we hypothesized that damage patterns of plant attackers play an important role in determining the plant defense patterns. To test this hypothesis, we selected leafminer, which has a special feeding pattern more similar to pathogen damage than chewing insects, as our model insect, and Arabidopsis thaliana as the response plants. The local and systemic responses of Arabidopsis thaliana to leafminer feeding were investigated using the Affymetrix ATH1 genome array. Damaged leaves of Arabidopsis thaliana for local damage analysis and the intact leaves on the same plant for systemic damage analysis were separately frozen by liquid nitrogen. Then, we used an Affymetrix ATH1 Arabidopsis microarray to study the expression changes pattern of Arabidopsis thaliana to pea leafminers damage, both locally (LI) and systemically (SI). We downloaded data from the web database and used hierarchical clustering to explore the relationships of Arabidopsis thaliana expression pattern to different kinds of attackers.

G3P triggered changes in systemic transcriptome

Project description:Goal of this study was to determine changes in transcription profile in mock versus G3P treated plants. Arabidopsis (Col-0 ecotype) plants were infiltrated with petiole exudate, with or without G3P, and distal leaves were sampled 24 h post treatments.

Root and shoot Jamonic Acid induction in Brassica oleraceae

Project description:Brassica oleraceae plants were treated with jasmonic acid either at the roots or two leaves. An acidic (HCl) water sollution with the same pH as the jasmonic acid sollution was also applied to two leaves of the root jasmonic acid treated plants, and to the roots of leaf jasmonic acid treated plants. Control plants received a mock treatment on roots and leaves with acidic water of the same pH as the jasmonic acid sollution. The whole root system and two systemic leaves were harvested separately at 6, 18 and 30 h after treatment. For each time point, tissue and treatment, three biological replicates (except two replicates for 'Root-Cont-18h' sample) were made consisting of pooled tissue samples from 10 plants. Gene expression was analyzed in both tissues using the 29,000 element Arabidopsis Oligonucleotide Microarrays (Qiagen-Operon Arabidopsis Genome Array Ready Oligo Set version 3.0).

Arabidopsis thaliana wild type mechanical damage (MD) vs herbivore wounding (HW)

Project description:Transcriptional profiling of Arabidopsis thaliana wild type (WT) comparing MD (mechanical damage) and HW (herbivore wounding). The differences in the biochemical responses to herbivory seen prompted us to search for less obvious differences between treatments using gene expression profiling. Biological replicates: 4 Two-condition experiment, MD vs. HW Arabidopsis leaves of WT plants. Biological replicates: 4 biological replicates.
