The Influence of Symbiont Identity on the Proteomic and Metabolomic Responses of the Model Cnidarian Aiptasia to Thermal Stress.

ABSTRACT: We examined the effects of symbiont identity and heat stress on the host metabolome and proteome in the cnidarian-dinoflagellate symbiosis. Exaiptasia diaphana ('Aiptasia') was inoculated with its homologous (i.e., native) symbiont Breviolum minutum or a heterologous (i.e., non-native) symbiont (Symbiodinium microadriaticum; Durusdinium trenchii) and thermally stressed. Integrated metabolome and proteome analyses characterised host thermal responses between symbioses, with clear evidence of enhanced nutritional deprivation and cellular stress in hosts harbouring heterologous symbionts following temperature stress. Host metabolomes were partially distinct at the control temperature; however, thermal stress caused metabolomes of anemones containing the two heterologous symbionts to become mo
