Data on plant legacy effects on total and active microbial successions
Plants shape soil microbial communities through their root architecture, their rhizodeposits and return of dead plant material to the soil. These interactions can have a strong influence on the soil organic carbon dynamics. However, it is unclear whether the plant species effects on the soil microbial community could influence the organic carbon mineralization through plant legacy effects. We conducted an experiment with two phases, the first phase corresponded to the “plant-soil experiment” and the second phase referred to the “litter-carbon mineralization experiment”. In the present work, we aimed at providing a dataset outlining the changes induced by the growth of two phylogenetically distinct plants, a common plant model (Arabidopsis thaliana (Linnaeus, 1753) Heynhold, 1842) and a crop (Triticum aestivum (Linnaeus, 1753) on active and total bacterial and fungal community composition. Three planters (bare soil, A. thaliana and T. aestivum) were placed in an environmental growth chamber during 63 days (plant-soil experiment). To identify early plant legacy effects on soil microbiota, both DNA (total microbial community) and RNA (active microbial community) were used to quantify microbial abundances (quantitative PCR) and identify the changes in microbial diversity using a 16S rRNA gene and ITS amplicon sequencing approach (Illumina). Here, we provided a dataset with the bacterial and fungal OTUs abundances (expressed in copy number of gene) and the chemical composition of the different soils.
