Mode de reconnaissance hôte symbionte en milieux extrêmes : cas du modèle symbiotique Rimicaris exoculata
Provedor de dados: 5
Autores: Le Bloa, Simon.
Deprived of light, the deep-sea hydrothermal vents are extremes ecosystems sustained by micobial chemosynthesis. These environments are colonized by animal species living in close relationships with these chemoautotrophic micro-organisms, eating them or establishing long term interactions with them, may they be trophic or not only. The shrimp Rimicaris exoculata is an endemic hydrothermal species of the Mid-Atlantic Ridge (MAR) sites. This crustacean represents the predominant macrofauna of some sites of the MAR. It lives in symbiotic association with two distinct microbial communities qualified as ectosymbiosis. One is located in its gill chamber and one in its gut. First, this work focused on the study of bacterial communication (Quorum Sensing or QS)...

ABSTRACT Quorum sensing is considered one of the most important discoveries in cell-to-cell communication. Although revealed in Bacteria, it has been identified as well as a mechanism present in the other two domains, Eukaryota and Archaea. This phenomenon consists mainly of an exchange and sensing of "words" produced by each cell: chemical signals known as autoinducers. The process takes places at high cell densities and confined environments, triggering the expression of specific genes that manifest in a determined phenotype. Quorum sensing has a fundamental importance in the organisms' fitness in natural ecosystems since it activates many of the traits needed by cells to survive under specific conditions, and thus a wide variety of chemical signals,...
