Network built based on the correlation among SOC-correlated metabolites, genes, and QTLs. Genes are shown as reverse arrows with a distinct color per co-expression module. All modules significantly correlated with SOC were shown in this network, except for module 68, module 134, and module 135. The QTLs were detected simultaneously by the significant associated genes (eQTL) and metabolites (mQTL) in this triple relationship network
