Les réseaux mycorhiziens

Au cours de son développement dans le sol, un champignon peut rencontrer plusieurs plantes différentes, il se forme alors des réseaux qu’on appelle les réseaux mycorhiziens. Ce réseau joue un rôle clé dans le développement et la survie des plantes. En effet, la symbiose entre le champignon et la plante permet d'une-part des échanges de nutriments entre plantes qui s'avèrent nécessaires pour certaines plantes non chlorophylliennes et d'autre-part des échanges d'informations nécessaires à leurs survie en cas d'attaque par un parasite. De plus, les graines issues de plantes qui sont en symbiose avec les champignons établissent à leur tour ...

It remains largely unknown how these pressures trigger evolutionary changes for various phenotypic traits. We address this issue here for temperate European oaks (Quercus petraea and Q. ...
