Project description:In this study, we provide a global overview of genome-wide OsHOX24 binding sites in rice under control and desiccation stress conditions in wild-type and OsHOx24 overexpressing rice plants (H49 line) via chromatin immunoprecipitation sequencing (ChIP-sequencing) approach. We identified numerous downstream targets of OsHOX24 under desiccation stress and control by analyzing the comprehensive binding site map of OsHOX24 at whole genome level in rice.

Project description:Spingomonas wittichii strain RW1 can completely oxidize dibenzo-p-dioxins and dibenzofurans, which are persistent contaminants of soils and sediments. For successful application in soil bioremediation systems, strain RW1 must cope with fluctuations in water availability, or water potential. The objectives of this study were to characterize how strain RW1 responses to changes in different components of the total water potential (solute and matric potential) and to then connect these responses to more realistic scenarios of soil desiccation. To accomplish this task, transcriptome profiling was used to investigate the effects of decreasing the solute potential with sodium chloride (solute stress), decreasing the matric potential with high-molecular weight polyethylene glycol (matric stress), or inoculating cells directly into unsaturated sand (sand desiccation stress). Transcriptome profiling revealed a general response to solute, matric, and sand desiccation stress that involved synthesizing trehalose and modifying the composition of exopolysaccarides. Transcriptome profiling also revealed responses that were unique to each stress. Only solute and matric stress triggered the down-regulation of flagella genes. Only solute and sand desiccation stress triggered the up-regulation of two RNA polymerase ECF-type sigma factors along with several membrane proteins, mechanosensitive channels, and solute transporters. Finally, only matric stress triggered the up-regulation of the RNA polymerase sigma-32 factor along with several molecular chaperones. Together, this study revealed a general response to solute, matric and sand desiccation stress but also unique responses to only a subset of these stresses, suggesting that each stress affects strain RW1 in a fundamentally different way. Comparative transcriptome profiling was performed to assess the effects of acute (30 min) solute and matric stress (3 samples for acute solute stress, 3 samples for acute matric stress, 3 controls), the effects of chronic (24 hours) solute and matric stress (3 samples for chronic solute stress, 3 samples for chronic matric stress, 3 controls), and the effects of sand desiccation stress (4 samples for sand desiccation treatment, 3 controls).

Project description:Desiccation tolerance has been implicated as an important characteristic that potentiates the spread of the bacterial pathogen Acinetobacter baumannii through hospitals on dry surfaces. Despite the potential importance of this stress response, scarce information is available describing the underlying mechanisms of A. baumannii desiccation tolerance. Here we characterize the factors influencing desiccation survival of A. baumannii. At the macroscale level, we find that desiccation tolerance is influenced by cell density, growth phase, and desiccation medium. Our transcriptome analysis indicates that desiccation represents a unique state for A. baumannii compared to commonly studied growth conditions and strongly influences pathways responsible for proteostasis. Remarkably, we find that an increase in total cellular protein aggregates, which is often considered deleterious, correlates positively with the ability of A. baumannii to survive desiccation. We show that artificially inducing protein aggregate formation increases desiccation survival, and more importantly, that proteins incorporated into cellular aggregates can retain activity. Our results suggest that protein aggregates may promote desiccation tolerance in A. baumannii through preserving and protecting proteins from damage during desiccation until rehydration occurs.
