Frankia Symbiosis: Proceedings of the 12th Meeting on Frankia and Actinorhizal Plants, Carry-le-Rouet, France, June 2001

The 12th meeting on Frankia and Actinorhizal Plants that took place in Carry-le-Rouet, France in June 2001 was the opportunity for scientists to communicate about latest developments on this symbiosis that concerns a wide range of dicotyledonous plants, initiates ecological successions and is used in a number of countries to protect crops from winds or improve soil status. Selected papers on plant ecology, __Frankia's__ genetics or physiology, and host plants' genetics or physiology are published in this special __Plant & Soil__ issue.
