Schematic representation of the gene cascades in symbiotic signaling symbiotic genes identified in the Medicago truncatula and Lotus japonicus genomes were classified according to their putative roles in root nodule symbiosis. The genes identified in A. evenia spp. serrulata are black and the symbiotic genes for which no transcripts were detected are grey. Regulation of transcription during the nodulation kinetics is in the circle: in white for constitutive expression; in red for up-regulation; in green for down-regulation.
