Fig. 6: Conceptual scheme of tripartite metabolic interactions within the Ianthella basta holobiont.
From: Taurine as a key intermediate for host-symbiont interaction in the tropical sponge Ianthella basta

A proposed metabolic network between the dominant gammaproteobacterial symbiont, ‘Candidatus Taurinisymbion ianthellae’, the dominant ammonia-oxidizing thaumarchaeal symbiont, ‘Candidatus Nitrosospongia ianthellae’, the marine sponge host, Ianthella basta, and the surrounding environment.
