Symbiosis: Enforced Surrender?



Scientists from INRA and Lorraine University in France unraveled a key mechanism in the symbiosis between fungi and trees. During this mutually beneficial interaction, the fungus takes control of its host plant by injecting a small protein that neutralizes its immune defenses thereby allowing the fungus to colonize the plant. This finding is a major advance in our understanding of the evolution and functioning of symbiotic interactions between fungi and plants - relationships that play a significant role in supporting the health and sustainability of our natural ecosystems. These results are published in the advance online edition of the PNAS on 19 May 2014.
