ADAPTATION TO HYDROSTATIC PRESSURE SHAPES PROTEOME DYNAMICS IN CORROSIVE SULFATE-REDUCING BACTERIA

ABSTRACT: Microbially influenced corrosion (MIC) poses a major threat to metal structures across various industries, resulting in substantial economic losses and environmental risks. As deep-sea exploration expands, understanding MIC under high hydrostatic pressure becomes increasingly critical. Microorganisms in these extreme environments undergo distinct structural and metabolic adaptations to survive and thrive. In this study, we employed a proteomic approach to examine the lifestyle and corrosive potential of two sulfate-reducing bacteria (SRB) species with different pressure optima under simulated depths ranging from the sea surface to 3000 meters. Species-specific corrosion mechanisms and unique proteomic signatures associated with pressure adaptation were identified, correlating with opposing trends in corrosion rates. Our findings emphasize the need to characterize microbial physiology in relation to environmental conditions to better predict corrosion risks in extreme deep-sea settings.

Protein expression plasticity contributes to heat and drought tolerance of date palm

Project description:Climate change is increasing the frequency and intensity of warming and drought periods around the globe, currently representing a threat to many plant species. Understanding the resistance and resilience of plants to climate change is, therefore, urgently needed. As date palm (Phoenix dactylifera) evolved adaptation mechanisms to a xeric environment and is able to tolerate large diurnal and seasonal temperature fluctuations, we studied the protein expression changes in their leaves, volatile organic compound emissions, and photosynthesis in response to variable growth temperatures and soil water deprivation. Plants were grown under controlled environmental conditions under simulated Saudi Arabian summer and winter climates followed by drought stress. We show that date palm is able to counteract the harsh conditions of the Arabian Peninsula by adjusting the abundances of proteins related to the photosynthetic machinery, abiotic stress and secondary metabolism. Under summer climate and water deprivation, these adjustments included efficient protein expression response mediated by heat shock proteins and the antioxidant system to counteract reactive oxygen species formation. Proteins related to secondary metabolism were downregulated, except for the P. dactylifera isoprene synthase (PdIspS), which was strongly upregulated in response to summer climate and drought. This study reports for the first time, the identification and functional characterization of the gene encoding for PdIspS, allowing future analysis of isoprene functions in date palm under extreme environments. Overall, the current results show that protein reprogramming of date palm leaves contribute to heat and drought tolerance. We conclude that the protein plasticity of date palm is one important mechanism of molecular adaptation to remarkable environmental fluctuations.

Expression data of endoploidy-specific cells (with DNA content 2C, 4C, 8C and 16C)

Project description:Endocycle is an alternative cell cycle during which the DNA is replicated in the absence of cytokinesis, resulting in cellular endopolyploidy. The endocycle is frequenctly observed in plant species that grow under extreme conditions. Thus, endopolyploidy has been postulated to be a mechanism facilitating adaptive growth. We used microarrays to assess endoploidy-dependant gene expression profiles in Arabidopsis thaliana root and to understand how subpopulations of cells with different endoploidy contributes to plant growth under different environmental conditions

Thermococcus eurythermalis A501, high hydrostatic pressure

Project description:In this study, we performed a global quantitative proteomic analysis under extreme temperatures, pH, hydrostatic pressure (HP) and salinity on an archaeal strain, Thermococcus eurythermalis A501. Here is the result of pressure adaptation: HP (40 MPa) tested under 85°C and 95°C, and the optimal culture condition (85°C, pH 7, 2.3% NaCl, 10 MPa) was used as the control.

RADOX’ Reduced Abdominal Distension and Oxygen Delivery

Project description:The use of laparoscopic surgery is continuing to increase in colorectal resection and expected reach 80% in the next 10 years. Although laparoscopic (keyhole) or minimally invasive surgery can lead to faster recovery it can also put significant stresses on the patient’s heart and cause fluctuations in blood pressure due to the extreme headdown positioning and abdominal insufflation of carbon dioxide gas. We have performed several surgical cases under deep neuromuscular block and this has allowed surgery to operate at lower abdominal pressures (from 14 down to 8 mmHg). This put less strain on the heart and allowed higher cardiac outputs. This study will look at whether deep neuromuscular block is beneficial for patients by 1. Increasing oxygen delivery, measured using oesophageal doppler monitoring of cardiovascular variables intraoperatively 2. Allowing surgery at lower abdominal insufflation pressures if they have a deep block 3. Reducing patient’s analgesic requirements postoperatively in recovery and at 4 hours

Physiological, biochemical and genome-wide transcriptional analysis reveals that elevated CO2 mitigates the impact of combined heat wave and drought stress in Arabidopsis thaliana at multiple organizational levels

Project description:Genome-wide transcriptional profiling of Arabidopsis thaliana to a combination of heatwave and drought under ambient and elevated CO2. Goal of this study was elucidate the transcriptional responses to a combination of heat wave and drought, and to see how these responses are modifed under future climate (high) CO2. Climate changes increasingly threaten plant growth and productivity. Such changes are complex and involve multiple environmental factors, including rising CO2 levels and climate extreme events. As the molecular and physiological mechanisms underlying plant responses to realistic future climate extreme conditions are still poorly understood, a multiple organizational level-analysis (i.e. eco-physiological, biochemical and transcriptional) was performed, using Arabidopsis exposed to incremental heat wave and water deficit under elevated CO2.The climate extreme resulted in biomass reduction, photosynthesis inhibition, and considerable increases in stress parameters. Photosynthesis was a major target as demonstrated at the physiological and transcriptional levels. In contrast, the climate extreme treatment induced a protective effect on oxidative membrane damage, most likely as a result of strongly increased lipophilic antioxidants and membrane-protecting enzymes. Elevated CO2 significantly mitigated the negative impact of a combined heat and drought, as apparent in biomass reduction, photosynthesis inhibition, chlorophyll fluorescence decline, H2O2 production and protein oxidation. Analysis of enzymatic and molecular antioxidants revealed that the stress-mitigating CO2 effect operates through up-regulation of antioxidant defense metabolism, as well as by reduced photorespiration resulting in lowered oxidative pressure. Therefore, exposure to future climate extreme episodes will negatively impact plant growth and production, but elevated CO2 is likely to mitigate this effect.
