Functional classification of differential expressed genes (DEGs) based on the clusters of orthologous groups (COGs). a PstDC3000 and (p)ppGpp⁰_PstDC3000. b PssB728a and (p)ppGpp⁰_PssB728a. DEGs were defined as genes with a |log₂FC| value ≥1 and a p value < 0.05. Up and down regulated genes were indicated by red and blue bars, respectively
