Fig. 6: The link between selected root microbiome functions and their associated taxonomy.

Link between order level root microbiome and genes of denitrification (a) and type VI secretion system (T6SS) (b). Relative abundance of each taxon under aCO2 and 100 ppm nitrate is represented by the size of the yellow node, and relative abundance is indicated in brackets near each taxon. Line width represents amount of gene. Width of gene rectangle indicates relative abundance of this gene in metagenome.
