A Proteomic Analysis of Desiccation Tolerance in Racomitrium canescens

ABSTRACT: The moss Racomitrium canescens has strong desiccation tolerance; it can remain almost completely desiccated for years and yet recover within minutes of rehydration. Dissecting the mechanisms underlying such desiccation tolerance in bryophytes could identify candidate proteins that improve plant drought tolerance. The mechanisms involved in recovery from desiccation was explored using label-free-quantitative proteomics comparing desiccated Racomitrium canescens samples rehydrated for 1 min or 6 h.

Eggs of the mosquito Aedes aegypti survive desiccation by rewiring their polyamine and lipid metabolism

Project description:Upon water loss, some organisms pause their life cycles and escape death. While widespread in microbes, this is less common in animals. Aedes mosquitoes are vectors for viral diseases. Aedes eggs can survive dry environments, but molecular and cellular principles enabling egg survival through desiccation remain unknown. In this report, we find that Aedes aegypti eggs, in contrast to Anopheles stephensi, survive desiccation by acquiring desiccation tolerance at a late developmental stage. We uncover unique proteome and metabolic state changes in Aedes embryos during desiccation that reflect reduced central carbon metabolism, rewiring towards polyamine production, and enhanced lipid utilization for energy and polyamine synthesis. Using inhibitors targeting these processes in blood-fed mosquitoes that lay eggs, we infer a two-step process of desiccation tolerance in Aedes eggs. The metabolic rewiring towards lipid breakdown and dependent polyamine accumulation confers resistance to desiccation. Furthermore, rapid lipid breakdown is required to fuel energetic requirements upon water re-entry to enable larval hatching and survival upon rehydration. This study is fundamental to understanding Aedes embryo survival and in controlling the spread of these mosquitoes.

Desiccation Tolerance of Arabidopsis thaliana seeds

Project description:Desiccation tolerance (DT) allowed seed plants to conquer ecosystems with long periods of limited water availability. This adaptive features allows seeds to remain dried for very long times without losing their ability to germinate. There is little information about all the signaling components required to achieve DT and on how transcription factors (TFs) modulate global DT processes. We performed RNA-seq experiment and carbohydrates profiles of lec1, lec2, fus3 and abi3, as well as their corresponding wild types, at three stages of seed development 15, 17 and 21 DAF (day after open flower) belonging to the seed desiccation period. A complex experimental design approach and regulatory networks prediction were used to identify differentially expressed genes specifically involved in DT process. In order to identify mechanisms involved in the acquisition of DT during seed development, we designed a comparative transcriptomic analysis between the seed desiccation intolerant (DI) mutants lec1-1, abi3-5 and fus3-3, the desiccation tolerant mutant lec2-1 and the desiccation tolerant weak allele of abi3 (abi3-1) with their respective wild type controls. This analysis should allow to identify genes that are differentially expressed in the desiccation intolerant mutants respect to tolerant mutants and WT controls.

Genome-wide Transcriptional Analysis of Genes Associated with Desiccation Stress in Anopheles gambiae

Project description:Anopheles gambiae mosquitoes play an important role in malaria transmission. In sub-Saharan Africa, the dry season can last several months. The mechanisms for mosquito population to survive through the dry season are poorly understood. One possible mechanism is that adults increase their desiccation tolerance over the dry season. Genetic analyses have shown that inversions 2La, 2Rb, 2Rc, 2Rd and 2Ru are associated with aridity resistance, however little is known about the transcriptional response of genes in response to desiccation. The results of the present study demonstrate that desiccation affects expression of genes associated with several mosquito physiological mechanisms, including those that protect against water loss, but all structural related genes decreased their expression. The identified differentially expressed genes in response to desiccation stress can lay a foundation for better understanding of molecular mechanisms underling dry-season survival of An. gambiae mosquitoes, so it may provide a different option for malaria vector control. Transcriptional profiles of Anopheles gambiae female mosquitoes were exposed to 70% (standard) or 30% (desiccated) RH without any access to sugar and water at 0hr, 18hr or 36hr.

Proteomics evidences of a systemic response to desiccation in the resurrection plant Haberlea rhodopensis.

Project description:According to the systems biology approach, genomics tells what can happen, transcriptomics what appears to be happening, metabolomics what has happened and proteomics what makes it happen. Thereby, to get a better what makes resurrection plants extremely tolerant to drought, we explored changes in the resurrection proteome and cellular ultrastructure of Haberlea rhodopensis in response to desiccation. Because genomic and proteomic data concerning resurrection plants are limited, particularly for H. rhodopensis, we identified proteins based on previous transcriptomic studies. For the identified proteins, fold changes and differences in transcript levels between fresh and dry plants were analyzed; proteins significantly enriched in various biological processes and metabolic pathways were detected using metabolomic metadata. The results confirmed that the transcription of different genes is regulated as previously described at the proteomic level; new genes were identified in desiccation tolerance, posttranscriptional regulation events, and posttranslational regulation events. We revealed new evidences about organelle and cell preservation, posttranscriptional and posttranslational regulation, photosynthesis, primary metabolism, and phagocytosis in H. rhodopensis. These findings can inform further genomic and evolutionary studies, as well as targeted genetic engineering to improve drought tolerance in crops as a response to climate change.

Characterizing Acinetobacter baumannii desiccation tolerance.

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.

CsrA-controlled proteins important for Acinetobacter baumannii desiccation tolerance

Project description:Hospital environments serve as excellent reservoirs for the opportunistic pathogen Acinetobacter baumannii in part because it is exceptionally tolerant to desiccation. To understand the functional basis this trait, we used transposon sequencing (Tn-seq) to identify genes contributing to desiccation tolerance in A. baumannii strain AB5075. We identified 142 candidate desiccation tolerance genes, one of which encoded the global post-transcriptional regulator CsrA. We characterized CsrA in more detail by using proteomics to identify proteins that were differentially present in wild type and csrA mutant cells. Among these were a predicted universal stress protein A, an iron-containing redox protein, a KGG-domain containing protein, and catalase. Subsequent mutant analysis showed that each of these proteins was required for A. baumannii desiccation tolerance. The amino acid sequence of the KGG-domain containing protein predicts that it is an intrinsically disordered protein. Such proteins are critical for desiccation tolerance of the small animals called tardigrades. This protein also has a repeat nucleic acid binding amino acid motif, suggesting that it may protect A. baumannii DNA from desiccation-induced damage.
