Learning unit contents

The objectives of this thematic week are to tackle the following questions: which are the actual physico-chemical limits of Life on Earth? Which is the phylogenetic and metabolic diversity of the organisms living in extreme conditions? Which mechanisms have they invented to accomplish their life cycle in these conditions? The adaptations of organisms to extreme conditions (pH, temperature, pressure, osmotic pressure) will be analysed. The phylogenetic analyses allow to localize the extremophilic organisms in the three branches of the Tree of Life, and we will examine their diversity in the global context of the rise and evolution of Life in our solar system. Moreover, for evolution and diversity, it is necessary that new mechanisms allow for genetic 'novelty' and adaptations. The different types of mechanisms will be presented, from mutations to lateral gene transfer. Then, 2 particular groups of microorganisms will be presented in more details (Cyanobactéries et Archébactéries).

Three courses are given in the frame of the Thematic week: 1) Biodiversity of the extremophiles (A.Wilmotte) 1H30 2) Generation of the genetic diversity (A. Wilmotte) 1H30 3) Cyanobacteria, Archea (A. Wilmotte) 2H
Two courses will be given in the frame of the thematic week:
adaptation to extreme pressure (1 h)
adaptation to extreme pH (1h)
