A The general life cycle of the entomopathogenic nematode Heterorhabditis on an insect (made with help of BioRender). B The diagrammatic representation of initial stages of the maternal transmission of the symbiont bacteria. When the IJs exit diapause, they regurgitate the symbiont bacteria and become completely bacteria free before reassociating with their symbiont bacteria later on during the development. The reassociation of symbiont bacteria results in formation of a persistent symbiont bacterial biofilm in the posterior intestinal cells on the nematode. The green colour shows bacteria, arrow indicates direction of bacterial movement, and the yellow shaded box indicates early-adult stage of nematode. C Early-adult stage of symbiotic and axenic Heterorhabditis bacteriophora used for RNA-sequencing. The image was created by overlapping DIC and fluorescence images of axenic early-adult devoid of bacterial biofilm and the bacterial biofilm in the posterior intestine of early-adult stage of symbiotic nematode
