Using Shewanella baltica ecotypes as a model for transcriptional variation

Project description:Assessment of individual whole cell transcriptional variation among closely related bacterial ecotypes Here we used 4 replicates each containing 3 independent biological replicates as well as dye swaps per each replicate. We hybridized in a two color format but analyzed in a one color format.

Potential role of natural variation in the Arabidopsis CBF Pathway contributing to local adaptation of ecotypes collected from Italy and Sweden

Project description:The two Arabidopsis ecotypes that are adapted to Italy and Sweden, respectively, showed different degree of freezing tolerance. By comparing the low temperature transcriptomes of the IT and SW ecotypes, we showed CBF pathway plays a significant role in natural variation of freezing tolerance.

Transcription profiling of Arabidopsis ecotypes to auxin to asses natural variation of auxin response

Project description:To assess natural variation of downstream auxin responses we subjected 7 different arabidopsis ecotypes to a time course of auxin treatments. 7d-old seedlings grown in liquid culture have been treated for 0, 30 min, 1h and 3h with 1 µM IAA. Experiment Overall Design: 83 samples were used in this experiment

Potential role of the CBF Pathway contributing to local adaptation of ecotypes collected from Italy and Sweden

Project description:The two Arabidopsis ecotypes that are adapted to Italy and Sweden, respectively, showed different degree of freezing tolerance. By comparing the low temperature transcriptomes of the IT and SW ecotypes with the CBF pathway being knocked out, we showed the CBF pathway plays a significant role in natural variation of freezing tolerance.

Daphnia ecotypes fed lab versus natural resources

Project description:Consumer-resource interactions are a central issue in evolutionary and community ecology because they play important roles in selection and population regulation. Most consumers encounter resource variation at multiple scales, and respond through phenotypic plasticity in the short term or evolutionary divergence in the long term. The key traits for these responses may influence resource acquisition, assimilation and/or allocation. To identify candidate genes, we experimentally assayed genome-wide gene expression in pond and lake Daphnia ecotypes exposed to alternate resource environments. One was a simple, high-quality laboratory diet, Ankistrodesmus falcatus. The other was the complex natural seston from a large lake. In temporary ponds, Daphnia generally experience high-quality, abundant resources, whereas lakes provide low-quality, seasonally shifting resources that are chronically limiting. For both ecotypes, we used replicate clones drawn from a number of separate populations.

Comparative transcriptome analysis of responses of Arabidopsis ecotypes to cold stress

Project description:Transcriptional variation, also called expression level polymorphism (ELP), contributes to intra-specific phenotypic variation in many organisms. Differentially expressed transcripts are typically enriched for stress-related genes, suggesting that differences in response to the environment are a particularly common point of divergence among gentoypes. Analysis of ELPs also has been suggested as a way to assess unintended consequences of transgene introduction; however, it is important that interpretation of transcriptional changes be performed within the context of potential fitness effects. In these studies we sought to examine differential gene expression in response to cold for two widely used Arabidopsis thaliana ecotypes, C24 and Columbia (Col).

arabidopsis ecotypes-Transcriptionnal response to potyviruses infection in Arabidopsis

Project description:ra06-05_potyvirus-ecotypes - arabidopsis ecotypes - Common and specific genes deregulated in response to various potyviruses in different Arabidopsis genetic backgrounds. - Four different Arabidopsis ecotypes were inoculated with one Potyviruse. About 4 weeks after sowing, the 6 expanded leaves plants were inoculated with the different viruses or were mock-inoculated. Seven days after inoculation, inoculated leaves were collected, RNA was extracted and virus infection controlled. RNA fron infected plants was then used for microarrays hybridization. Three biological repeat have been done and two dye-swap. Keywords: normal vs disease comparison
