Abstract

The multi-omics data being generated in the thematic projet "Integrating Dimensions of Microbial Biodiversity across Land Use Change in Tropical Forests" (Process: 2014 / 50320-4) require a quantitative interpretation of the interactions among the three dimensions (phylogenetic, genetic and funcional) of microbial diversity. The aim of this project is to develop a data integration model, based on the relationship between phenotypic characteristics and gene functions of methanogenic Archaea from metagenomic, metatranscriptomics and target sequencing data (multi-omics approaches). The data integration will be performed by in silico modeling, based on the trait values that determine the relative fitness of methanogenic archaea in soils under different land use, environment factors (different levels of moisture and emissions of greenhouse gases) and temporal scales. These values will be extracted from the identification of methane producing Archaea: (i) 16S rRNA gene phylogenic analysis of Archaea communities and (ii) pairwise statistics integration between datasets of adjacent dimensions, based on microbial genome assembly, methanogenesis gene expression quantification and metadata measurements. Finally, the third step (iii) includes evaluating the traits using MicroTrait-ME model. Integrative modeling will rely on an massive use of bioinformatics tools, being applied to a multi-omic dataset generated from a microcosm experiment. This in situ experiment simulates a field condiction, with different moisture levels in a forest-pasture conversion system as variables. It is important to highlight that 90% of the raw data to be explored in this model was already generated by the Prof. Tsai laboratory staff.
