Description: Within the Biodiversity Exploratory Priority Program, Core Project 8 has the mission to deliver high quality base line data on structural and functional diversity of soil microorganisms in relation to land use. Soil microorganisms, defined as having a body size below 50 micro m, encompass millions of species belonging to all regna. Their distribution is extremely dense but heterogeneous among soil microhabitats. Only a small part of them is active at each time point, and they function within complex interaction networks to ensure matter turnover, water cycle, productivity and biodiversity aboveground, but also regulate atmosphere gas composition. Due to advances in molecular biology and bioinformatics within the last decades, soil microbial communities can now be rationally characterized at different scales from the pedon to the region. In this new phase, Core Project 8 will significantly extend its service to the priority program by covering Bacteria and Archaea in addition to the general and arbuscular mycorrhizal soil fungi analyzed in the past. Accordingly, this core project will now be maintained by three PI groups. While a barcode sequencing approach of DNA and cDNA will enable us to characterize diversity of fungi and bacteria in 1.110 plots at both taxonomical and functional levels, metagenomics will provide enlarged functional data and allows us to cover further groups such as Archaea and micro-eukaryotes. By merging the barcode data in cross-kingdom co-occurrence network analyses using commonly improved bioinformatics and advanced statistic tools, we will identify key stone species, which will be functionally characterized based on the obtained metagenomics data. This program will be performed on all 300 experimental plots of the three exploratory regions as well as in all treatments of the new extensive grassland and forest gap experiments. For all these plots, Core Project 8 also has the central mission of extracting and distributing soil nucleic acids (DNA & RNA) for all contributing projects dealing with microorganisms. Further we also provide bioinformatics and specific sequencing support, thus warranting a high quality standard of data, for meta-analyses, and synthesis all over the Biodiversity Exploratories.
