Project description:Plants employ diverse strategies to cope with different types of heat stress. The response to short-term acute heat stress differs significantly from that to prolonged, moderate heat stress followed by severe stress events. After experiencing prolonged moderate heat stress, plants exhibit a more robust response to subsequent severe stress, a phenomenon known as thermopriming or acquired thermotolerance. Thermopriming creates a memory by maintaining the heat stress (HS) memory-related genes in an alert state. In this work, we investigated the role of Arabidopsis Universal Stress Protein 1 (USP1) in plant heat stress responses. CRISPR-Cas9 generated knockout usp1 mutant lines showed no morphological changes in development in normal growth conditions. However, usp1 mutant plants showed enhanced levels of apoplast hydrogen peroxide and superoxide reactive oxygen species accumulation upon heat stress. Transcriptome analyses revealed that genes related to protein folding, electron transport, and oxidative phosphorylation are strongly upregulated in usp1 mutant plants. USP1 is essential for acquired thermotolerance, as usp1 mutant plants show decreased transcript levels of heat stress response genes and reduced H3K4me3 enrichment at memory gene loci. USP1 is involved in thermopriming by interacting with HEAT SHOCK TRANSCRIPTION FACTOR A2 (HSFA2). Biochemical assays showed that USP1 functions as a molecular chaperone, protecting the transcription factor HSFA2 from heat-induced denaturation. Moreover, usp1 mutants are compromised in heat stress memory but show normal responses to acute heat stress similar to hsfa2 mutants. These data show that USP1 plays an important role as a chaperone of HSFA2 in mediating plant heat stress memory.

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.

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.

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.

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.

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.

Project description:We generated a comprehensive RNAseq expression atlas for several stress conditions in order to analyze changes in the gene expression during adaptation to mild stresses. The stresses are divided into two main groups: the “nutrient stresses” and the “environmental stresses”. Nutrient stresses include nutrient depletion (-N, -P, -S, -micronutrients), salt stress (+NaCl), osmotic stress (+mannitol) and control. The environmental stresses consist of high light, prolonged darkness, heat, cold and control.

Project description:Short-term brassinosteroid-induced antioxidant activity and photosynthetic capability increases are indicated across numerous plant species and stress conditions. However, the long-term implications of exogenous brassinosteroid (BR) treatment and its reliance on reactive oxygen species (ROS) is not well defined. We investigated how manipulating BR in germinating wheat alongside a ROS-inhibitor could affect yield component outcomes when plants were subjected to heat stress during reproduction. Inhibiting BR reduced superoxide dismutase (SOD) activity, increased lipid peroxidation, and correlated with multiple yield component losses compared to controls following heat stress. Despite a greater initial reduction in effective photochemical yield and SOD activity during heat stress for BR-treated plants compared to controls, BR-treated plants had sustained SOD activity and photochemical capability over prolonged heat stress compared to continued losses observed in control plants. The inhibition of ROS proliferation during BR treatment did not consistently affect the long-term response of antioxidant activity tested but did reduce BR induced photosynthetic resilience during reproductive heat stress. This research suggests a more limited role of ROS and BR for enduring antioxidant activity and highlights their persistent interaction for photosynthetic capability under heat stress conditions.

Project description:Prolonged exposure to high temperatures may cause heat-related illnesses, such as cramps, syncope, exhaustion or even stroke in some individuals. Heat-related injuries remain a threat to the health and operational effectiveness of military personnel, athletes and the general public. Heat injury victims experience long-term complications that may include multi-system organ (liver, kidney, muscle) and neurologic damage, as well as reduced exercise capacity and heat intolerance. Findings from our laboratory using a developed heat stress model show that about 1/3 of mice are heat-intolerant and vulnerable to heat injury even though they are from the same mice litter. We examined if there is any genetic causation to this pattern of observation between the two groups of mice classified (Heat Intolerant and Heat Tolerant). We would like to screen Heat Tolerant and Heat Intolerant mice samples using microarray technology and examine their microRNA and mRNA for possible gene-specific differences between the two groups (6 mice per group). The results from this proposed animal research will help identify and select potential markers that can be used as a pre-screen to identify heat intolerance and assess heat injury recovery in humans.
