Fig. 2From: Genome comparisons provide insights into the role of secondary metabolites in the pathogenic phase of the Photorhabdus life cycleSchematic summary of the intricate tripartite lifecycle of Photorhabdus highlighting the produced specialized metabolites and predicted functions (indicated by a ‘?’ where unproven associations exist). Nematodes infect insects and release the bacteria inside the hemolymph before undergoing several rounds of development while the insect is killed. The bacteria release several compounds (dashed arrows) that variously affect the insect’s immune response. DAR = dialkylresorcinol, PPY = photopyroneBack to article page
