Fig. 5From: Combined metagenomics and metabolomic analysis of microbial community structure and metabolic function in continuous soybean cropping soils of Songnen Plain, ChinaThe statistics of gene annotation of the KEGG pathway analysis (a). Heatmap of microbial relative abundance of the top 15 KEGG pathways level 2 (b). The Z-values obtained after normalizing the functional relative abundance for each row are presented as the values corresponding to the middle heatmap.
