GNPS Unknown precursors in forest soil Dissolved Organic Matter by direct-injection ESI tandem MS

ABSTRACT: This dataset consists of fragmentation data obtained from a representative forest soil DOM sample. The sample was originally taken in November 2005 in a German conifer forest ("Wetzstein") and freeze-dried for storage. In 2018, the sample was reconstituted in bi-distilled water and extracted by SPE (PPL Bond Elut) at an extraction efficiency of 87%. This dataset contains dat for four selected precursor mixtures (isolated at 1 Da window) at m/z 241, 301, 361 and 417. This spans the usual ion abundance range of MS1 fingerprints of terrestrial DOM. Each precursor mixture was measured non-fragmented ("CID0") and at collision energies (CID, N2) of 15, 20 and 25 in reduced profile mode. Each MS/MS spectrum was obtained by averaging 150 scans. For more details, see the connected manuscript.

Project description:A functional biodiversity microarray (EcoChip) prototype has been developed to facilitate the analysis of fungal communities in environmental samples with broad functional and phylogenetic coverage and to enable the incorporation of nucleic acid sequence data as they become available from large-scale (next generation) sequencing projects. A dual probe set (DPS) was designed to detect a) functional enzyme transcripts at conserved protein sites and b) phylogenetic barcoding transcripts at ITS regions present in precursor rRNA. Deviating from the concept of GeoChip-type microarrays, the presented EcoChip microarray phylogenetic information was obtained using a dedicated set of barcoding microarray probes, whereas functional gene expression was analyzed by conserved domain-specific probes. By unlinking these two target groups, the shortage of broad sequence information of functional enzyme-coding genes in environmental communities became less important. The novel EcoChip microarray could be successfully applied to identify specific degradation activities in environmental samples at considerably high phylogenetic resolution. Reproducible and unbiased microarray signals could be obtained with chemically labeled total RNA preparations, thus avoiding the use of enzymatic labeling steps. ITS precursor rRNA was detected for the first time in a microarray experiment, which confirms the applicability of the EcoChip concept to selectively quantify the transcriptionally active part of fungal communities at high phylogenetic resolution. In addition, the chosen microarray platform facilitates the conducting of experiments with high sample throughput in almost any molecular biology laboratory. In this study, two independent RNA samples from a pine forest soil were labelled and hybridised to a custom-made EcoChip microarray consisting of about 9000 probes targeting expressed fungals genes and about 5000 probes targeting the precursor-rRNA of different fungal lineages
