DNA metagenomes - Soil biodiversity

The dataset includes raw DNA sequences for 630 samples collected as part of the LUCAS 2018 Soil survey for the biodiversity module. The dataset includes DNA reads annotated as antibiotic resistance and biosynthesis genes (ARG and ABG, respectively) revealed in the metagenomes from 630 soil samples collected during the LUCAS 2018 Soil survey

Description

The dataset includes raw DNA sequences for 630 samples collected as part of the LUCAS 2018 Soil survey for the biodiversity module. The raw DNA sequences have been deposited in the NCBI Sequence Read Archive (SRA) under the primary accession code PRJNA1032917 (BioSamples SAMN38018670 – SAMN38019327). Samples from four locations were re-sampled, and thus sequenced twice (i.e., 630 total samples from 626 sampling sites). Specifically, samples numbered 59, 102, 113, 116 were re-sequenced as samples numbered 138, 601, 717, and 258, respectively.

The “ABG_ARG_LUCAS” table includes the number of DNA reads annotated as antibiotic resistance and biosynthesis genes (ARG and ABG, respectively) revealed in the metagenomes from 630 soil samples collected during the LUCAS 2018 Soil survey (GENES sheet). To identify ARGs (genes that, if expressed, provide antibiotic resistance to their host), we employed the short-sequence model of DeepARG v.1.0.2 (Arango-Argoty et al., 2018). ABGs were identified using the eggNOG-mapper v.2.1.2 (Cantalapiedra et al., 2021) based on eggNOG orthology data v.5.0.2 (Huerta-Cepas et al., 2019). Details on the search parameters are available in the published paper "A trait-based ecological perspective on the soil microbial antibiotic-related genetic machinery".

The “ABG_ARG_LUCAS” table contains additional information on the DNA reads generated for each sample from which the ABG and ARG data were retrieved (SAMPLES sheet). To merge the “SAMPLES” and “GENES” sheets, one should use the column BARCODE_ID.

Additional details on DNA extraction and sequencing methods, as well as sources of climatic data, can be found in paper “A trait-based ecological perspective on the soil microbial antibiotic-related genetic machinery”. The source code used for data analyses in this study is available for public access on GitHub https://github.com/Mycology-Microbiology-Center/LUCAS_ABRG (DOI: 10.5281/zenodo.10039980).
