AbstractMarine sponges (Phylum Porifera) harbor complex and species-specific microbiota1, while continuously being exposed to microbes from the surrounding seawater. With respect to microbial abundances in their mesohyl matrix2,3, sponges are described either as >high microbial abundance> (HMA) or >low microbial abundance> (LMA). The mechanisms for microbe recognition and and maintenance of the symbiotic association remain unknown4. Our experimental approach revealed the mediation of pattern recognition receptors (i.e., NLRs, Ig-like and SRCR domain-containing genes) in the response of sponge hosts to microbes, although different receptor repertoire was regulated in the HMA and the LMA species. These results encourage further functional studies to elucidate the mechanisms of host-microbe interactions in this ancient phylum
