^aGenes of Rhizobium leguminosarum biovar viciae 3841 (Rlv3841) are classified by whether they are unique to this genome (R) or have homologs in the genomes of A. tumefaciens (A), S. meliloti (S), or M. loti (M). ^bOf the 546 genes shared by the three rhizobia (R+S+M) but missing from A, 264 had homologs in B. japonicum, a distantly related rhizobium.
