Warm temperature-triggered developmental reprogramming requires VIL1-mediated, genome-wide H3K27me3 accumulation in Arabidopsis.

Project description:Changes in ambient temperature immensely affect developmental programs in many species. Plants adapt to high ambient growth temperature in part by vegetative and reproductive developmental reprogramming, known as thermo-morphogenesis. Thermo-morphogenesis is accompanied by massive changes in the transcriptome upon temperature change. Here, we show that transcriptome changes induced by warm ambient temperature require VERNALIZATION INSENSITIVE 3-LIKE 1 (VIL1), a facultative component of the Polycomb repressive complex PRC2, in Arabidopsis. Warm growth temperature elicits genome-wide accumulation of H3K27me3 and VIL1 is necessary for the warm temperature-mediated accumulation of H3K27me3. Consistent with its role as a mediator of thermo-morphogenesis, loss of function of VIL1 results in hypo-responsiveness to warm ambient temperature. Our results show that VIL1 is a major chromatin regulator in responses to high ambient temperature.

Comparative transcriptomic analyses of Spring OilSeed Rape (SOSR)accessions in response to warm temperature.

Project description:Elevated growth temperatures are negatively affecting crop productivity and increasing yield losses. Root traits associated with improved adaptation to rising temperatures are a promising approach to generate new varieties better suited to face the environmental constrains caused by climate change. In this study, we identified various Brassica napus roots traits altered in response to warm temperature. Thus, different combination of changes in specific root traits results in an extended and deeper root system. This overall root growth expansion facilitates root adaptation by maximizing root-soil surface interaction and increasing its ability to explore extended soil areas. We associated these traits to coordinated cellular events, including changes in cell division and elongation rates, that drive the increase in root growth triggered by warm temperature. Comparative genome wide transcriptomic analysis revealed the main genetic determinants of these RSA changes and uncovered the necessity of a tight regulation of the heat shock stress response to adjust root growth to warm temperature. Our work provides a phenotypic, cellular and genetic framework of root response to warming temperatures that will help to harness root adaptation mechanisms for crop yield improvement under the future climatic scenario.

A conserved signaling complex controls warm temperature-mediated plant growth

Project description:The model plant Arabidopsis thaliana responds to mild high temperature by increased elongation growth of organs to enhance cooling capacity, in a process called thermomorphogenesis. Our understanding of the genetic regulation of thermomorphogenesis has increased in recent years. However, hardly anything is known about molecular mechanisms outside A. thaliana and cellular signaling pathways have been underexplored. Therefore, we mapped changes in protein phosphorylation in A. thaliana and crops exposed to warm temperature. Based on these results, we identified and characterized a novel, functionally conserved signaling complex of MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE KINASEs (MAP4KS) in warm temperature-mediated growth regulation in plants. This contributes to our understanding of warm temperature signaling, and can help guarantee food security under a changing climate

Gene expression regulated by warm temperature in C. elegans

Project description:Stress resistance induced by mild environmental stress protects animals against aging-associated cellular damages and promotes longevity. Here, we reveal that mild heat triggers innate immune and detoxification responses that confers longevity at warm temperatures. We compared the transcriptome of 25°C-cultivated animals to that of 15°C controls through RNA-seq analysis. A total of 1958 transcripts were differentially regulated, with 1143 up-regulations and 815 down-regulations.

Warm Water Versus Room Temperature Water Immersion Colonoscopy

Project description:Water immersion insertion has been documented to decrease procedure-related discomfort during colonoscopy. There was used warm water infusion for colonoscope insertion in most of the water immersion colonoscopy trials. The investigators have been using room temperature water (20-24°C) for water immersion and the investigators did not notice any drawback of it. In our opinion, it is simpler and cheaper option for water immersion colonoscopy and proof of its efficacy and safety could support the use of water immersion technique in routine practice. The primary endpoint is cecal intubation time and the investigators suppose that the use of warm water infusion does not shorten it significantly. Patient comfort during colonoscope insertion, water consumption, length of the scope while reaching the cecum, need for external compression, need for positioning of the patient and endoscopist´s difficulty with colonoscopy will be also assessed.

Transcriptome and translatome profiling of warm temperature (35°C -> 38.5°C) treated mouse embryonic fibroblast cells

Project description:To see a possible effect of a physiological warm temperature shift (WTS, 35°C to 38.5°C) on Per2 transcription and translation in mammalian cells, we performed RNA-seq and Ribo-seq using dexamethasone-synchronized mouse embryonic fibroblast cells with or without WTS treatment at a circadain rising phase of Per2.
