Fig. 4From: De novo transcriptome analysis of Medicago falcata reveals novel insights about the mechanisms underlying abiotic stress-responsive pathwayExpression pattern of genes involved in early symbiotic nodulation. a Expression pattern of key genes under cold stress. b Expression pattern of key genes under dehydration stress. c Expression pattern of key genes under high salinity stress. Additional abbreviations are as follows: NFR (nod factor receptor); DMI (does not make infections); NSP (Nodulation signalling pathway); ERN (ERF required for nodulation); and ENOD (early nodule). Filled colours correspond with their degree of regulation by the stressesBack to article page
