Integrative Biology of Marine Organisms
UMR 7232

In the GENOPHY team we study algal host - virus interactions. We are particularly interested in the biology, ecology and evolution of the Mamiellophyceae, which are unicellular picoeukaryotic marine green algae. These picoalgae serve as models for diverse research projects, ranging from their physiology to their evolutionary history, including their interactions with the environment, and their relationships with large DNA viruses.

Many of our analyses are based on genomic approaches. Using microbiological and molecular techniques we are isolating new strains of picoalgae and viruses to compare their growth and physiological characteristics. Knowledge acquired about these species may then be used as a tool to capture relevant information from environmental sample databases in silico (usually DNA sequence data, either amplified from marker genes or from metagenomes produced by Next Generation Sequencing, and other sources).

Our research interests include:

- combining experimental approaches and comparative analysis of genomes of picoeukaryotes and their viruses, thereby linking analyses of their genomes, their phenotypes and environmental data;

- co-evolutionary processes between phytoplankton and their viruses;

- understanding the population diversity of algae within this group, particularly in the NW Mediterranean basin.
