Project description:Monitoring microbial communities can aid in understanding the state of these habitats. Environmental DNA (eDNA) techniques provide efficient and comprehensive monitoring by capturing broader diversity. Besides structural profiling, eDNA methods allow the study of functional profiles, encompassing the genes within the microbial community. In this study, three methodologies were compared for functional profiling of microbial communities in estuarine and coastal sites in the Bay of Biscay. The methodologies included inference from 16S metabarcoding data using Tax4Fun, GeoChip microarrays, and shotgun metagenomics.

Project description:Paleoproteomics is the proteomics analysis of ancient proteins, which may be better preserved than DNA in fossil inclusions and particularly in amber fossilized tree resin. However, only yeast proteins have been previously suggested as identified by paleoproteomics analysis conducted in fossil amber. In this study, we developed and applied a paleoproteomics approach to study fossil arthropod inclusions in five Burmese (also known as Burmite and Kachin) amber (Cretaceous, ca. 99 mya) pieces. The results of morphological analysis supported the first report of fossil scavenger mite (Holothyrida, Neothyridae) together with co-inclusions of putative lacewing larva (Neuroptera, Chrysopidae) and thrip Frankliniella sp. (Thysanoptera, Thripidae), the identification of Cornupalpatum sp. (Ixodidae), and two mites Prostigmata (Acari, Trombidiformes, Tetranychidae). A control amber fragment derived from the piece with mite-lacewing-thrip co-inclusions was included in the analysis. The paleoproteomics analysis was conducted by Mass Spectrometry (MS) and Liquid Chromatography-Tandem Mass Spectrometry by searching results from all fossil amber pieces against a compile database containing all sequences from Acari, Insecta and Enterobacterales taxonomies in Uniprot together with contaminants database supplemented with human keratins and bovine trypsin. Identified proteins were selected for analysis based on those identified by MS with more than two peptides per protein and at least one peptide with 1% FDR. Paleoproteomics identified protein orthologs present in fossil amber inclusions of ca. 99 mya in arthropods and other organisms. These results provide a paleoproteomics approach to complement morphological studies in amber inclusions.

Project description:We sequenced messenger RNA from mixed stages of the two-spotted spider mite (Tetranychus urticae) reared on bean (Phaseolus vulgaris cv California Red Kidney; the laboratory host plant for mites) and two Arabidopsis thaliana accessions which were considered to either be susceptible (Kondara) or resistant (Bla-2) to mite feeding. This pilot experiment was conducted to assess gene expression differences of mites grown on sensitive versus resistant Arabidopsis accessions, as well as differences in mites feeding on different host species. The expression data was used for gene model validation of genes predicted by EuGene in the spider mite genome and to assess gene expression levels. Examination of gene expression of spider mites reared on beans and two Arabidopsis accessions (Kondara and Bla-2).

Project description:In this study, we profiled the transcriptional changes in a polyphagous spider mite, Tetranychus urticae, after adaptation to spatial and tempospatial stress. We show heritable down-regulation of genes encoding for core enzymes involved in the citric acid and gluconeogenesis/glycolyse pathways (glucose 6-phosphatase among others). Additionally, we observe heritable transcriptional changes in amino acid pathways (methionine, tyrosine and phenylalanine) and in laterally acquired genes from bacteria (cobalamin-independent methionine synthase). By similiar study results in other organisms, we argue that these heritable transcriptional changes (partially) underpin the changed life history traits observed in our experimental evolution set-up.

Project description:Twenty-four nucleotide long miRNAs (lmiRNAs) direct DNA methylation at target genes and regulate their transcription. The evolutionary origin of lmiRNAs and the range of lmiRNA-mediated regulation remain obscure. Here, we reannotated lmiRNAs and their targets in rice by applying stringent criteria. We found that the majority of lmiRNAs are derived from MITEs and most sites targeted by MITE-derived lmiRNAs reside within MITEs, suggesting co-evolution of lmiRNAs and their targets through MITE amplification. lmiRNAs undergo dynamically changes under stressed conditions and the genes targeted by lmiRNAs show an enrichment for stress responsive genes, suggesting that lmiRNAs are widely involved in plant response to stresses. We constructed the evolutionary histories of lmiRNAs and their targets. lmiRNAs emerged before or when the AA genome was diverged, while the emergence of lmiRNA targets coincided with or followed the emergence of lmiRNAs. Furthermore, we found that the sequences of a lmiRNA target site underwent variations, coincident with the divergence of rice accessions and the distribution of rice accessions in different geographical locations and climatic conditions. Our findings highlight MITEs as an important origin of lmiRNAs and suggest that the evolution of lmiRNA-target regulatory modules may contribute to rice adaptation to environmental changes.

Project description:The purpose of this study was to identify genes in keratinocytes and fibroblasts in human skin equivalents that changed expression in response to the burrowing of live scabies mites. Four biological replicates for the uninfested control condition and five biological replicates for the treatment conditions (live mites, mite extract) were processed for gene expression analysis using Affymetrix Human Gene 1.0 ST arrays.
