AB - <jats:title>Summary</jats:title><jats:p>Oomycetes were recently discovered as natural pathogens of<jats:italic>Caenorhabditis elegans</jats:italic>and pathogen recognition alone was shown to be sufficient to activate a protective transcriptional program in the host characterised by the expression of multiple<jats:italic>chitinase-like</jats:italic>(<jats:italic>chil</jats:italic>) genes. However, the molecular mechanisms underlying oomycete recognition in animals remain fully unknown. We performed here a forward genetic screen to uncover regulators of<jats:italic>chil</jats:italic>gene induction and found several independent loss-of-function alleles of<jats:italic>old-1</jats:italic>and<jats:italic>flor-1,</jats:italic>which encode receptor tyrosine kinases belonging to the<jats:italic>C. elegans</jats:italic>-specific KIN-16 family. We present evidence that OLD-1 is an active kinase mounting the immune response, and FLOR-1 a pseudokinase that is also required for the response and regulates the distribution of OLD-1 at the epidermal membrane. Interestingly, the<jats:italic>old-1</jats:italic>locus is adjacent to the<jats:italic>chil</jats:italic>genes in the nematode genome, thereby revealing a genetic cluster important for oomycete-resistance. Furthermore, we identify the VAB-3/PAX-6 transcription factor known for its role in visual system development to regulate<jats:italic>old-1</jats:italic>expression, and consequently the spatial pattern of the response to oomycete recognition. Taken together, our study reveals both conserved and species-specific factors shaping the response to oomycete recognition.</jats:p>
