Putative promiscuous symbionts in deep-sea corals and crinoids may contribute to nitrogen cycling
Our findings suggest that nitrogen cycling plays a key role in structuring microbial symbioses in deep-sea coral-crinoid holobionts. The promiscuous distribution of symbionts across hosts implies that metabolic interactions, such as DNRA-driven ammonia provisioning, could underpin resilience in nutrient-limited environments. This study highlights the importance of microbial versatility in deep-sea ecosystems and provides new insights into how cross-host symbiosis may contribute to biogeochemical cycling in the ocean.
