Project description:Low temperature stress in a number of African countries, such as Botswana, at night can effect the growth and development of bambara groundnut, leading to losses in potential crop yield. Therefore, we made an attempt to identify and analyze the genes and gene modules associated with low temperature stress response in bambara groundnut using the cross-species microarray technique, as bambara groundnut has no microarray chip, coupled with network-based analysis.

Project description:As part of the EcoToxChip project, 49 distinct exposure studies were conducted on three lab model species (Japanese quail, fathead minnow, African clawed frog) and three ecologically relevant species (double crested cormorant, rainbow trout, northern leopard frog), at multiple life stages (embryo, adult), exposed to eight chemicals of environmental concern (ethinyl estradiol-EE2, hexabromocyclododecane-HBCD, lead-Pb, selenomethionine-SeMe, 17β trenbolone-TB, chlorpyrifos-CPF, fluoxetine-FLX, and benzo [a] pyrene-BaP. Whole transcriptome analyses were conducted on these samples resulting in a rich RNA seq dataset covering various species, life stages and chemicals, which is one of the largest purposeful complications of RNA seq data within ecotoxicology. Recently, a unified bioinformatics platform of relevance to ecotoxicology, EcoOmicsAnalyst and ExpressAnalyst, was developed to facilitate RNA Seq analysis of non-model species lacking a reference transcriptome. The platform uses the Seq2Fun algorithm to map RNA-seq reads from eukaryotic species to an ortholog database comprised of protein sequences from >600 eukaryotic species (EcoOmicsDB) with a translated search. The availability of these tools presents a unique opportunity to examine the EcoToxChip RNA Seq dataset for cross species comparisons. This work shows the potential of the EcoOmicsAnalyst and Seq2Fun platform to facilitate fast and simple analysis of RNA Seq datasets from non-model organisms with unannotated genomes and conduct comparative transcriptomic analysis across various species and life stages for cross-species extrapolation.

Project description:Temperature, as a universal enviromental factor, has prolonged effect on physiological and pathological functions of different species. In order to expolore the temperol effect of temperature on C.elegans longevity, we used microarray to check the whole-genome expression profiling of L4 larvae and Day3-old adults of C.elegans maintaining at different temperature

Project description:Environmental factors shape the phenotypes of multicellular organisms. The production of stomata—the epidermal pores required for gas exchange in plants—is highly plastic, and provides a powerful platform to address environmental influence on cell differentiation [1-3]. Rising temperatures are already impacting plant growth, a trend expected to worsen in the near future [4]. High temperature inhibits stomatal production but the underlying mechanism is not known [5]. Here, we show that elevated temperature suppresses the expression of SPEECHLESS (SPCH), the bHLH transcription factor that serves as the master regulator of stomatal lineage initiation [6,7]. Our genetic and expression analyses indicate that the suppression of SPCH and stomatal production is mediated by the bHLH transcription factor PHYTOCHROME-INTERACTING FACTOR 4 (PIF4), a core component of high temperature signaling [8]. Importantly, we demonstrate that upon exposure to high temperature, PIF4 accumulates in the stomatal precursors and binds to the promoter of SPCH. In addition, we find SPCH feeds back negatively to the PIF4 gene. We propose a model where the high temperature-activated PIF4 binds and represses SPCH expression to restrict stomatal production at high temperature. Our work identifies a molecular link connecting high temperature signaling and stomatal development, and reveals a direct mechanism by which production of a specific cell lineage can be controlled by a broadly-expressed environmental signaling factor.

Project description:Temperature and pH-sensitive, self-assembled polymeric nanoparticles, made of N-isopropyl acrylamide (NIPAAM), N-vinyl pyrrolidone (VP), and acrylic acid (AA) are biocompatible and have been used in the past with several drugs for site-specific delivery of different formulations. In the present study, the nano LC-MS/MS proteomic approach was employed to compare the secretome of Artemisia absinthium extract loaded polymeric nanoparticles-treated MCF-7 and MDA MB-231 cell lines targeted against the tumor microenvironment and comparison with corresponding untreated cell lines as a control to identify potential therapeutic targets and easily-accessible biomarkers among differentially expressed secretory proteins.

Project description:Gene expression Arabidopsis 24h cold-treated, 4c, seedlings to identify a *gold-standard* set of cold-responsive transcripts. Most of the CBF overexpression lines are in WS, therefore, it is necessary to identify a consistent set of transcripts that are detectible as cold-induced on the ATH1 platform for both WS and Columbia, so that appropriate comparisons can be made to determine the effects of low temperature in CBF overexpressing or loss of function plants in a WS background and an attempt can be made to compare the results of altered CBF function to published microarray studies. We aimed to identify a set of *gold-standard* cold responsive transcripts that were induced in multiple different experiments performed by different researchers and were detectible in both the WS and Col-0 ecotypes. This series contributes the 24h cold-treated WS ecotypes, along with additional Col-0 cold-treated and control samples for normalization purposes. Keywords: Expression profiling by array

Project description:Background: Ocean temperatures are projected to increase over the coming century, with dramatic consequences for the marine biosphere. Diatoms are important contributors to marine primary production and the ocean carbon cycle, yet the molecular mechanisms that regulate their acclimation and adaptation to temperature are poorly understood. Method: Here we use a transcriptomic approach to identify the molecular mechanisms associated with temperature acclimation and adaptation in closely related colder- and warmer-adapted diatom species. Results: We find contrasting patterns of differential expression at sub- and supra-optimal temperatures across the two species, which may be due to adaptive changes in baseline expression. Frontloaded and divested pathways indicate protein processing machinery, membrane structure, and the balance between temperature-independent photosynthesis and temperature-dependent metabolism are key elements of adaptation to temperature changes. Conclusions: Our findings suggest that transcriptional frontloading and divestment may provide a framework to interpret diatom acclimation and adaptation to temperature and success under future warming.

Project description:Plants developed a plasticity to environmental conditions, such as temperature, that allows their adaptation. A change in ambient temperature leads to changes in the transcriptome in plants, such as the production of different splicing isoforms. Here we study temperature induced alternative splicing events in Arabidopsis thaliana wild-type and two epigenetic mutants, sdg8-2 and sdg26-1 using an RNA-seq approach.
