  abstract = {{C}omparative transcriptomics of two actinorhizal symbiotic plants, {C}asuarina glauca and {A}lnus glutinosa, was used to gain insight into their symbiotic programs triggered following contact with the nitrogen-fixing actinobacterium {F}rankia. {A}pproximately 14,000 unigenes were recovered in roots and 3-week-old nodules of each of the two species. {A} transcriptomic array was designed to monitor changes in expression levels between roots and nodules, enabling the identification of up-and downregulated genes as well as root-and nodule-specific genes. {T}he expression levels of several genes emblematic of symbiosis were confirmed by quantitative polymerase chain reaction. {A}s expected, several genes related to carbon and nitrogen exchange, defense against pathogens, or stress resistance were strongly regulated. {F}urthermore, homolog genes of the common and nodule-specific signaling pathways known in legumes were identified in the two actinorhizal symbiotic plants. {T}he conservation of the host plant signaling pathway is all the more surprising in light of the lack of canonical nod genes in the genomes of its bacterial symbiont, {F}rankia. {T}he evolutionary pattern emerging from these studies reinforces the hypothesis of a common genetic ancestor of the {F}abid ({E}urosid {I}) nodulating clade with a genetic predisposition for nodulation.},
