Correlations among genes associated with the processing of TeOM and their correlation to environmental variables. Correlations between the number of genes associated with lignin oxidation, cellulose and hemicellulose deconstruction, transporting systems (AAHS, ABC and TTT), lignin-derived aromatic compounds processing pathways (Ring cleavage pathways; Funneling pathways of dimers and monomers), and environmental variables (dissolved inorganic carbon—DIC, dissolved oxygen—DO, temperature, conductivity, sample depth—Depth and linear distance from the sampling site to the Amazon River source). Correlation coefficients are shown inside the boxes, and their color indicates the correlation strength. White boxes are non-significant correlations (p > 0.01)
