Fig. 1From: Expanding the view on the evolution of the nematode dauer signalling pathways: refinement through gene gain and pathway co-optionSummary of the signalling pathways known to control the switch between dauer and growth in C. elegans. Genes in a grey box are those whose function promotes the formation of the dauer stage. The function of the other genes leads to reproductive development. The red asterisk marks genes that are conserved in at least Clades III, IV and VBack to article page
