The Institute for Biological Sciences (INSB) at CNRS launched for the second year the call “Diversity of biological mechanisms” that aims at developing studies on so far non-canonical biological models and mechanisms.
Alexandre Berr project is titled: Nuclear organization in extremophytes, the key to thrive in extreme environments ?
A key issue for all living organisms exposed to stress is to protect their DNA to maintain genome integrity while allowing all genomic functions. Because the sacrosanct plant model A. thaliana is by no means a stress-tolerant species, it is unlikely to possess some of the stress determinants that were naturally selected in wild stress-tolerant plants. In this project A. Berr will question whether high-order or sharp nuclear-based mechanisms have emerged in the course of evolution to enable extremophile plants to thrive in extreme environments?
