Morphological, physiological, transcriptomic and metabolomic responses of Arabidopsis leaves to prolonged warming and heat shock

Project description:We sequenced mRNA from leaves of Arabidopsis under the control (CK), warming (W) and heat (H) treatments using the Illumina HiSeq4000 platform to generate the transcriptome dynamics that may serve as a gene expression profile blueprint for different response patterns under prolonged warming versus rapid-onset heat stress in Arabidopsis.

Transriptional profiling upon heat shock and recovery in cells deficient for FBXW7 and their wild type counterpart.

Project description:FBXW7 modulates stress response by post-translational modification of HSF1 HSF1 orchestrates the heat-shock response upon exposure to heat stress and activates a transcriptional program vital for cancer cells. Genes positively regulated by HSF1 show increeased expression during heat shock while their expression is reduced during recovery. Genes negatively regulated by HSF1 show the opposite pattern. In this study we utilized the HCT116 FBXW7 KO colon cell line and its wild type counterpart to monitor gene expression changes during heat shock (42oC, 1 hour) and recovery (37oC for 2 hours post heat shock) using RNA sequencing. These results revealed that the heat-shock response pathway is prolonged in cells deficient for FBXW7.

Differential expression of genes in Listeria monocytogenes under prolonged heat shock

Project description:Microarray analysis was performed to identify the differentially expressed genes during heat stress by comparing the transcriptome of L. monocytogenes under optimal temperature (37°C), and prolonged heat shock (60°C for 9 minutes) conditions.

Insights into the adaptive stress response of Arabidopsis thaliana to thermal stress by ribosomal profiling

Project description:Environmental stress is detrimental to plants viability and requires an adequate reprogramming of cellular activities to maximize plant survival. We present a global analysis of the adaptive stress response of Arabidopsis thaliana to prolonged heat stress. We combine deep sequencing of RNA and ribosome protected fragments to provide genome wide map of adaptation to heat stress on at transcriptional and translational level. Our analysis shows that the genes with the highest upregulation upon heat stress are known heat-responsive gene, chaperons and other genes involved in protein folding control. Majority of these genes exhibits increase on both transcriptional and translational level. No translational inhibition or ribosome stalling was observed, which can be observed in the early thermal stress response, indicating that plants alter their cellular composition in order to adapt to the prolonged exposure to increased temperatures.

Reorganization of 3D chromatin architecture of rice genomes during heat stress (ATAC-Seq)

Project description:Background: The three-dimensional spatial organization of the genome plays important roles in chromatin accessibility and gene expression in multiple biological process, and has been reported to be altered in response to environmental stress. However, the functional changes in spatial genome organization during environmental changes in crop plants are poorly understood. Results: Here we perform Hi-C, ATAC-seq and RNA-seq in two agronomically important rice cultivars, Nipponbare (Nip; Japonica) and 93-11 (Indica), to report a comprehensive profile of nuclear dynamics during heat stress (HS). We show that heat stress affects different levels of chromosome organization, including A/B compartment transition, increase in size of topologically associated domains, and loss of short-range interactions. The chromatin architectural changes were associated with chromatin accessibility and gene expression changes. Comparative analysis revealed that 93-11 exhibited more dynamic gene expression and chromatin accessibility changes, including of HS-related genes, consistent with observed higher HS tolerance in this cultivar. Conclusions: Our data uncovered higher-order chromatin architecture as a new layer in understanding transcriptional regulation in response to heat stress in rice.

A reversible light and genotype dependent acquired thermolerance response protects the potato plant from excessive temperature.

Project description:'Potato is particularly vulnerable to increased temperature, considered to be the most important uncontrollable factor affecting growth and yield. Here we describe an acquired thermotolerance response in potato, whereby treatment at a mildly elevated temperature (''acclimated'') primes the plant for more severe heat stress compared to control (''non-acclimated'') plants. We define the time course for acquiring thermotolerance and demonstrate that light is essential for the process. Physiological, transcriptomic and metabolomic approaches were employed to elucidate potential mechanisms that underpin the acquisition of heat tolerance and indicate a role for cell wall modification, auxin and ethylene signalling, and chromatin remodelling in acclimatory priming.'

Time series of gene expression profiles describing the temporal response to prolonged heat stress in C. elegans.

Project description:This experiment broadens our understanding of the temporal dynamics underlying the transcriptional response to heat stress. Using C. elegans hermaphrodite N2 populations, we have created a high-resolution time series of gene expression profiles taken at different time points during prolonged heat stress (35 C) conditions. Samples ware taken after 0h, 0.5h, 1h, 2h, 3h, 4h, 6h, 8h, and 12h of heat exposure with 3-5 biological replicas per time point.

Expression data from Arabidopsis seedlings heat-stressed in light environment

Project description:Plants transcriptome react to environment temperture changes profoundly. In Arabidopsis seedlings, genes response to temperature fluctuations to adopt the ever-changing ambient envrionment. 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.
