Identification of novel elements of the Drosophila blisterome sheds light on potential pathological mechanisms of several human diseases.

ABSTRACT: Main developmental programs are highly conserved among species of the animal kingdom. Improper execution of these programs often leads to progression of various diseases and disorders. Here we focused on Drosophila wing tissue morphogenesis, a fairly complex developmental program, one of the steps of which--apposition of the dorsal and ventral wing sheets during metamorphosis--is mediated by integrins. Disruption of this apposition leads to wing blistering which serves as an easily screenable phenotype for components regulating this process. By means of RNAi-silencing technique and the blister phenotype as readout, we identify numerous novel proteins potentially involved in wing sheet adhesion. Remarkably, our results reveal not only participants of the integrin-mediated machinery, but also components of other cellular processes, e.g. cell cycle, RNA splicing, and vesicular trafficking. With the use of bioinformatics tools, these data are assembled into a large blisterome network. Analysis of human orthologues of the Drosophila blisterome components shows that many disease-related genes may contribute to cell adhesion implementation, providing hints on possible mechanisms of these human pathologies.

Project description:The resurrection plant Craterostigma plantagineum possesses an extraordinary capacity to survive long-term desiccation. To enhance our understanding of this phenomenon, complementary transcriptome, soluble proteome and primary metabolome analyses were carried out on plant leaves collected from different physiological stages during a dehydration and rehydration cycle. A total of 7348 contigs, 611 proteins and 46 metabolites were differentially regulated across stages. Dynamic changes in transcript, protein and metabolite levels revealed a unique signature characterizing each stage. An overall low correlation between transcript and protein abundance suggests a prominent role for post-transcriptional modification in metabolic reprogramming to prepare plants to desiccation and recovery upon rehydration. The integrative analysis of three -omics datasets was performed with an emphasis on photosynthesis, photorespiration, energy metabolism and amino acid metabolism. The results revealed a set of fine regulations/changes that modulate primary metabolism to confer plasticity to metabolic pathways, thus optimizing plant performance under stress. For example, maintenance of cyclic electron flow and photorespiration and switch from C3 to Crassulacean acid metabolism (CAM) photosynthesis may contribute to partially sustain photosynthesis and minimize oxidative damage during dehydration. transcripts with a delayed translation, ATP-independent bypasses, alternative respiratory pathway and 4-aminobutyric acid (GABA) shunt may play a role in energy management, altogether conferring bioenergetic advantages to meet energy demands for survival during desiccation. This knowledge provides a high-resolution map of the changes occurring in the primary metabolism during dehydration and rehydration and enriches the current understanding of the molecular mechanisms underpinning plant desiccation tolerance. The datasets here provided will ultimately inspire biotechnological strategies for drought tolerance improvement in crops.
