KEGG Enrichment of DEGs in P. polymyxa SC2 (a) and pepper (b).

DEGs were also enriched according to the KEGG database [29]. Each column presents a path, and ordinate text indicates the name and classification of the path. The height of a column is expressed in ordinates enrichment rate (Enrichment Ratio = Sample Number/Background Number). *** p < 0.001, ** p < 0.01, and * p < 0.05
