Project description:Casuarina glauca belongs to a family of angiosperms called actinorhizal plants because they can develop nitrogen-fixing nodules in association with the soil bacteria Frankia. They can also develop arbuscular mycorrhizae (AM) while associated with Glomeromycota fungi. The aim of this transcriptomic study was to get a global view of the plant symbiotic genetic program in AM and to identify new key plant genes involved in endosymbioses.
