Comparison of partial amino acid sequences of NFRs in Arachis hypogaea, Glycine max, and Lotus japonicus. a Amino acid sequence of NFR1. b Amino acid sequence of NFR5. The sequences in red boxes are the extracellular LysM domains of NFRs. The sequences in blue boxes are the CXC motifs. Protein IDs were: GmNFR1A (ABB30246.1), GmNFR5A (NP_001341125.1), LjNFR1a (CAE02591.1), LjNFR1b (CAE02592.1), LjNFR5–1 (CAE02597.1)
