Fig. 6: Biosynthesis or biodegradation pathways associated with nettle and reed fertilizers.

The combination of metabolomics and microbiome datasets allows the reconstruction of (a) plant tissue disruption (cellulose degradation) and POPs release and degradation (anthracene, biphenyl) and (b) microbial production of plant signaling compounds that are beneficial to plant growth and pathogen resistance (indole-3-acetate, salicylic acid). c Taxon functional abundance of indole-3-acetate and salicylic acid. Pathways were reconstructed on the basis of the pathway maps available in KEGG. Metabolites detected in the datasets are identified with colors indicating their abundance in fertilizers (red, up; blue, down; yellow, fertilizer-only). Enzymes predicted to be present in fertilizer microbial communities are displayed with an asterisk and are listed in Supplementary Fig. 5. Source data are provided as a Source Data file.
