Pyrimidine/purine dinucleotide CT/GA-rich MRI (mid-range inhomogeneity) region. The identified MRI and flanking sequences in the pSymA of GR4-type isolates and that conserved on the chromosomes of S. meliloti and S. medicae are shown. Residues in color are different from the consensus sequence. The location of the replicon and GenBank accession numbers are shown
