Fig. 5From: Transcriptomic profiling of Burkholderia phymatum STM815, Cupriavidus taiwanensis LMG19424 and Rhizobium mesoamericanum STM3625 in response to Mimosa pudica root exudates illuminates the molecular basis of their nodulation competitiveness and symbiotic evolutionary historyNodulation gene operons in BP, CT and RM, colored following their regulation level (fold change) in response to root exudates at 4.5, 4.5 and 6 h post induction, respectively. Black triangles indicate the presence of a conserved nodbox (AATNGATTGTTTNGATNNNNNNNAT). The regulation color scale is indicated on the right side of the figureBack to article page
