Project description:<p>Anthropogenic activities cause the release of vast amounts of contaminants into the environment and thus also into surface- and groundwaters. Regulatory monitoring determines whether critical threshold concentrations are surpassed, by mostly occasional probing. This irregular testing, however, does not capture the intricacies of intra- and inter-annual contaminant dynamics, such as the emergence and mobilisation of contaminants in response to water flows. We report the detection and tracing of five contaminants in the 'Hainich Critical Zone Exploratory' (CZE) in central Germany, a monitoring site established for regular sampling of groundwater from different depths and locations along a hill-slope recharge area. The insect repellent DEET (N,N-diethyl-m-toluamide) and the coniferous resin acid 7-ODAA (7-oxodehydroabietic acids), the latter being volatilised from wood burning in ovens, show phases of seasonal dynamics in line with their release mode. Further, and alongside legacy herbicides (simazine and the triazine transformation product hydroxypropazine) and the concurrent flame retardant and plasticiser TPP (triphenyl phosphate), mobilisation events emerge from periods of high precipitation and water flows. This investigation highlights the persistence and mobilization of anthropogenic contaminants even in pristine environments. It illustrates the importance of long-term research for understanding ecosystem processes. The results add a note of caution for regulatory monitoring since also legacy contaminant levels may considerably vary over time.</p><p><br></p><p><strong>MS1 data</strong> is reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS8433' rel='noopener noreferrer' target='_blank'><strong>MTBLS8433</strong></a>.</p><p><strong>MS2 data</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS3533' rel='noopener noreferrer' target='_blank'><strong>MTBLS3533</strong></a>.</p>

Project description:Roots were collected from young trees outplanted in three regions in Germany (Schorfheide, Swabian Alb, Hainich) and used for RNA extraction. In each region four plots were sampled. Two plants used from each plot. The RNA of the plants per plot was pooled. Four technical replicates were prepared.

Project description:Nitrate-reducing iron(II)-oxidizing bacteria are widespread in the environment contribute to nitrate removal and influence the fate of the greenhouse gases nitrous oxide and carbon dioxide. The autotrophic growth of nitrate-reducing iron(II)-oxidizing bacteria is rarely investigated and poorly understood. The most prominent model system for this type of studies is enrichment culture KS, which originates from a freshwater sediment in Bremen, Germany. To gain insights in the metabolism of nitrate reduction coupled to iron(II) oxidation under in the absence of organic carbon and oxygen limited conditions, we performed metagenomic, metatranscriptomic and metaproteomic analyses of culture KS. Raw sequencing data of 16S rRNA amplicon sequencing, shotgun metagenomics (short reads: Illumina; long reads: Oxford Nanopore Technologies), metagenome assembly, raw sequencing data of shotgun metatranscriptomes (2 conditions, triplicates) can be found at SRA in https://www.ncbi.nlm.nih.gov/bioproject/PRJNA682552. This dataset contains proteomics data for 2 conditions (heterotrophic and autotrophic growth conditions) in triplicates.

Project description:affy_ath_2012_05 - affy_ath_2012_05 - The main objective is to determinate the influence of Ubiquitin-Like Proteases in plant transcriptional modulation. The experiment will also allow us to find what transcriptional cues are particularly affected in the mutants relatively to wild-type.-Seeds were stratified for 3 days at 4ºC in the dark. Afterwards, seeds were surface sterilized, sown onto MS media and grown at 23ºC, with 100 µE light condition, in long days (16h L/8h D). Each MS plate was dived in four, corresponding to a genotype (Col, AB, SIZ1 or SAB), and 10 seeds were sown per genotype. After 10 days, seedlings were collected and frozen in liquid nitrogen. Each replicate was made of ~40 seedlings coming from 4 different MS plates. Frozen plant material was grounded in an eppendorf tube using a mini pestle. RNA was extracted using RNeasy Plant Mini kit (QIAGEN cat.74904), following the manufacturer instructions (QIAGEN, Hilden, Germany). The RNA samples were DNase treated (Recombinant DNase I, Takara Biotechnology, Dalian, China) and subsequently cleaned by column using RNeasy Plant Mini kit (QIAGEN, Hilden, Germany).

Project description:Nitrate-reducing iron(II)-oxidizing (NDFO) bacteria are widespread in the environment contribute to nitrate removal and influence the fate of the greenhouse gases nitrous oxide and carbon dioxide. The autotrophic growth of nitrate-reducing iron(II)-oxidizing bacteria is rarely investigated and poorly understood. The most prominent model system for this type of studies is enrichment culture KS, which originates from a freshwater sediment in Bremen, Germany. A second NDFO culture, culture BP, was obtained with a sample taken in 2015 at the same pond and cultured in a similar way. To gain insights in the metabolism of nitrate reduction coupled to iron(II) oxidation under in the absence of organic carbon and oxygen limited conditions, we performed metagenomic, metatranscriptomic and metaproteomic analyses of culture BP. Raw sequencing data of 16S rRNA amplicon sequencing (V4 region with Illumina and near full-length with PacBio), shotgun metagenomics, metagenome assembly, raw sequencing data of shotgun metatranscriptomes (2 conditions, triplicates) can be found at SRA in https://www.ncbi.nlm.nih.gov/bioproject/PRJNA693457. This dataset contains proteomics data for 2 conditions in triplicates. Samples R23, R24, and R25 are grown in autotrophic conditions, samples R26, R27, and R28 in heterotrophic conditions.
