| Abstract | The main objective of this project is to study the molecular adaptation of Antarctic krill to thermal shocks and to identify possible metabolic pathways implemented during the response. This study joins in vivo physiological experiments and molecular analyses to estimate euphausian thermal tolerances but also to identify more precisely molecules implied in the response.
In parallel to the study of heat shock proteins (mainly HSP70 for a first part), a global search and characterization of new molecular stress markers, in relation with warmer temperature conditions, will be performed via a transcriptomic approach (micro-arrays) on experimented individuals of E. superba under different thermal conditions. These markers will enable us to estimate temperatures at which animals can be considered as stressed or close to lethal conditions. First results obtained with E. superba‘s HSP70s will be presented. |
