In the present work a molecular genetic analysis of the receptor part of the nfr5 gene in 15 plants of the conjugate collection (the plant component Melilotus albus, the bacterial component Sinorhizobium meliloti) has been done. Was studied the LysM domains structure and found a high level of the nucleotide polymorphism in LysM domains of this gene. A clear relationship of nucleotide and amino acid polymorphism in the receptor region of the nfr5 gene with the genetic diversity of the rhizobial component (bacterial symbiotic locus nodD) was observed. Based on these data, the computer modeling of binding of the bacterial Nod-factor with two different variants of the plant receptor was performed.
