It is conceivable that no known living entity in the major multicellular, eukaryotic lineages is completely devoid of microorganisms. Ranging from simple associations dominated by a single or few mutualist(s), such as the squid-Vibrio and gutless worm symbioses, to the complex “microbiomes” associated with e.g. the human gut, plant roots or marine corals and sponges, it seems indisputable that microorganisms in the three domains of life are capable of populating any micro-niche offered by their animal and plant hosts. Indeed, life, as we know, is strongly underpinned by inter-domain symbiotic relationships (Bacteria-Archaea-Eukarya).
In this context, the Marine Metagenomics and Microbial Ecology Team at BSRG seek to understand the causes and consequences of microbial diversity and function in nature, with emphasis on prokaryote-eukaryote symbioticrelationships in the marine realm. It applies molecular and bioinformatics toolsin conjunction with creative experimental designs to unravel the composition and function of symbiotic consortia in natural settings and microcosms, with the ultimate aim to harness and exploit the metabolic versatility of complex microbiomes for the development of renewable sources of biotechnological appliances.
Our current projects within this subject include
- Evolutionary and ecological relationships between hosts and symbionts;
- In-faunal and ad-plantae biogeochemical cycling;
- Symbiotic microorganisms and host developmental biology;
- Antibiotic biosynthesis and resistance;
- Horizontal gene transfer;
- Cultivation of as-yet uncultured symbiotic bacteria;
- Microbe-microbe and host-microbe chemical signalling;
- Potential biotechnological appliances and services deriving from symbiont-host biological activities;
- Responses of microbial communities to climate change and pollution;
- Model study systems include the microbiomes of marine sponges, corals, algae, seagrasses and fish, as well as rhizosphere- and human-associated microbial communities;
