Classification of metabolite-biomarkers of willow's leaves in response to the AMF Rhizophagus irregularis according to their participation in metabolic pathways/functions and chemical groups.

Biomarkers are classified as increased and decreased in colonized seedlings compared to controls. The code system of KEGG for pathways is used whereas for the chemical classification of metabolites information was retrieved from the database PubChem. A color gradient was used ranging from dark green (0) to red (36).
