Abstract
AbstractActinorhizal symbioses are mutualistic associations between plants belonging to eight angiosperm families and soil bacteria of the genus Frankia. These interactions lead to the formation of new root organs, actinorhizal nodules, where the bacteria are hosted and fix atmospheric nitrogen thus providing the plant with an almost unlimited source of nitrogen for its nutrition. Recent progress in actinorhizal plants and Frankia genomics has increased our understanding of the molecular events that control these symbiotic interactions. In this chapter, we summarise our current knowledge of the signalling mechanisms and cellular events that occur during the establishment of actinorhizal symbioses. We describe what is known about the signal exchanges occurring prior to infection. We give an overview of the cellular and molecular mechanisms controlling the infection of actinorhizal plant cells by symbiotic Frankia bacteria. Finally, we review what is currently known about actinorhizal nodule development.KeywordsRoot HairFrankia StrainActinorhizal PlantAuxin InfluxNodule LobeThese keywords were added by machine and not by the authors.
