Resumen:

To improve their nutrition, most plants associate with soil microorganisms, particularly fungi, to form mycorrhizae. A few lineages, including actinorhizal plants and legumes are also able to interact with nitrogen-fixing bacteria hosted intracellularly inside root nodules. In the N2-fixing root-nodule symbioses between actinorhizal plants and Frankia, our knowledge of the molecular biology of the symbiotic interaction has progressed considerably during the last decade. The onset of large-scale nodule transcriptome analysis in different actinorhizal systems have revealed the expression of numerous genes potentially implicated in actinorhizal nodulation providing access to more information on the symbiosis and its evolution. Moreover data suggest that the molecular mechanisms involved in these root nodule symbioses (RNS) have been partially recycled from more ancient and widespread arbuscular mycorrhizal (AM) symbiosis. In this chapter, we review all the recent advances and current researches on genomic applied to actinorhizal symbioses and give some potential future research directions. © 2015 by John Wiley & Sons, Inc.
