The Phaeoexplorer project (https://phaeoexplorer.sb-roscoff.fr/home/) aims to generate transcriptome data and annotated genome assemblies for a broad range of brown algal species at different phylogenetic distances from the model brown alga Ectocarpus. It is made in collaboration with the algal genetics group in Roscoff (https://www.sb-roscoff.fr/en/team-algal-genetics). During the sequencing step, we also obtained the genome of bacteria living on these algals. The bact_phaeoexplorer project aims to assemble and annotate these bacterial genomes in order to observe putative symbiotic bacteria-algal interaction.
For now, we have assembled more than 700 MAGs assigned to more than 200 bacteria species.We attempt to determine all their metabolic network and explore their metabolic complementarity with their algal host. This part is made with the collaboration of the Dyliss team (https://www-dyliss.irisa.fr/anne-siegel/) in Renne. This work will increase our comprehension of bacteria-algal interaction and lead the way to seaweed valorization.
