Project description:Dynamic trimethylation of histone H3 at Lys27 (H3K27me3) affects gene expression and controls plant development and environmental responses. In Arabidopsis thaliana, RELATIVE OF EARLY FLOWERING 6/JUMONJI DOMAIN-CONTAINING PROTEIN 12 (REF6/JMJ12) demethylates H3K27me3 by recognizing a specific DNA motif; however, little is known about how REF6 activates target gene expression after recognition, especially in environmental responses. In response to warm ambient temperature, plants undergo thermomorphogenesis, which involves accelerated growth, early flowering, and changes in morphology. Here we show that REF6 regulates thermomorphogenesis and cooperates with the transcription factor PHYTOCHROME INTERACTING FACTOR 4 (PIF4) to synergistically activate thermo-responsive genes under warm ambient temperature. The ref6 loss-of-function mutants exhibited attenuated hypocotyl elongation at warm temperature, partially due to down-regulation of GIBBERELLIN 20-OXIDASE2 (GA20ox2) and BASIC HELIX-LOOP-HELIX 87 (bHLH87). REF6 enzymatic activity is necessary for warm ambient temperature responses. Together, our results provide direct evidence of an epigenetic modifier and a transcription factor working together to respond to the environment.

Project description:To investigate the molecular basis of fluctuating temperature induced phenotypic plasticity, we ran genome-wide transcriptomic analysis on Drosophila melanogaster subjected to acclimation at constant (19 +/- 0 degree Celcius) and fluctuating (19 +/- 8 degree Celcius) temperatures and contrasted the induction of molecular mechanisms in adult males, adult females, and larvae. We investigated whether fluctuations act by permanently activating the involved mechanisms, or whether fluctuations repeatedly activate and repress mechanisms, during the hot (or heating) and the cold (or cooling) phase of thermal fluctuations. We show that adult flies acclimated to fluctuating temperatures tolerate high temperatures better than the constant temperature acclimated controls. Differential gene expression indicated that responses to thermal variability rely partly on life stage and sex specific mechanisms. Our results show that some of the involved mechanisms were permanently activated, while others tracked the thermal fluctuations. Further, for a number of genes, fluctuating temperature resulted in canalization of gene expression. Molecular mechanisms related to environmental sensing and chromatin reorganization seems to be important components of adaptive responses to thermal variability.

Project description:Plants transcriptome react to environment temperature changes profoundly. In Arabidopsis seedlings, genes respond to temperature fluctuations to adopt the ever-changing ambient environment. We used microarrays to detail the global programme of gene expression underlying heat stress response progress in Arabidopsis. Ten-day-old Arabidopsis seedlings were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to explore the heat stress response in transcriptome, thus we treat the plants with heat stress. While in order to identify the interaction between light and temperature signaling pathways in plant , we treat Arabidopsis with heat stress under both light and dark conditions. To that end, our plant tissues are grouped as: HS-LIGHT, HS-DARK,CONTROL-LIGHT,CONTROL-DARK.

Project description:Our manuscript aimed to use RNA sequencing technology to study the transcriptomics responses and mechanisms of this species to temperature fluctuations. We focused on both a short term and a more sustained exposure to heat stress. We report significant effects of temperature on the gene expression of Temora.

Project description:In this study we performed comprehensive analysis of changes in cell survival, vital parameters, plasticity, as well as transgene expression of placental MSCs after temperature fluctuations within the liquid nitrogen steam storage, mimicking long-term preservation in practical biobanking, transportation, and temporal storage. It was shown that viability and metabolic parameters of placental MSCs did not significantly differ after temperature fluctuations in the range from -196ºC to -100ºC in less than 20 cycles in comparison to constant temperature storage. However, increasing of the temperature range to -80ºC as well as increasing the number of cycles, leads to significant lowering of these parameters after thawing. The number of apoptotic changes increases depending on the number of cycles of temperature fluctuations. Besides, adhesive properties of the cells after thawing are significantly compromised in the samples subjected to temperature fluctuations during storage. Plasticity of placental MSCs was not compromised neither after cryopreservation with constant end temperatures nor with temperature fluctuations. However, regulation of various genes after cryopreservation procedures significantly varies. Alterations in structural and functional parameters of placental MSCs after long-term preservation should be considered in practical biobanking due to potential temperature fluctuations in samples. At the same time, plasticity and transgene expression are not compromised during studied storage conditions, while certain gene regulation is observed.

Project description:Temperature is one of the most impactful environmental factors in response to which plants adjust their growth and development. While the regulation of temperature signaling has been extensively investigated for the aerial part of plants, much less is known and understood about how roots sense and modulate their growth in response to fluctuating temperatures. Here we found that shoot and root growth responses to high ambient temperature are negatively correlated during early seedling development. A shoot signaling module that includes HY5, the phytochromes and the PIFs exerts a central function in coupling these responses and triggers long-distance signaling to control root growth and auxin levels in the root. In addition to the HY5/PIF dependent shoot module, a local regulatory axis composed of auxin biosynthesis and auxin perception factors mediates root responses to high ambient temperature. Together, our findings uncover that roots integrate long-distance signals with local hormonal inputs during thermomorphogenesis.
