Laboratory of Integrative Biology of Marine Models

The TCCD team studies how cell cycle and development are regulated by translation mechanisms and kinases signaling, in marine metazoans and human cell lines.

Our central research objective is to unravel the molecular mechanisms underlying brown algal chronobiology, with a particular focus on circasemilunar rhythms, which are tightly linked to tidal range cycles.

The BAG team aims to understand the structure, synthesis and functions from brown algal glycans. These glycans, or polysaccharides, are of physiological importance and constitute a key resource for various uses (food, hydrocolloids and nutraceuticals). To unravel their metabolic pathways, we use genomic and biochemical approaches, along with functional studies.

Red algae are ancient eukaryotes and important primary producers in coastal marine ecosystems. Some red algae have sulfated extracellular matrix (ECM) galactans: carrageenans and agars. These polymers are essential for algal biology and provide complex carbon sources for marine microbes.

The BABIM team aims at understanding the degradation and bioconversion of macroalgal biomass by heterotrophic bacteria, a crucial step in the marine carbon cycle. We integrate environmental microbiology studies with detailed molecular characterization of isolated bacterial degraders and evaluation of their potential applications.

Cell differentiation and Cell death

The Algal Genetics Group studies various aspects of brown algal biology including responses to pathogens, speciation, life cycle regulation and development

Group leaders: J. Mark Cock, Yacine Badis

The ABIE team aims at developing integrative biology approaches on different algal and bacterial models, from the molecular scale (structure/function analyses of proteins) to the level of the whole organism (or of several organisms in interactions) in comparative physiology studies.
