FIG 2.

Genome organization of phage ΦLM21 and comparison of its protein sequences with those of the other Sinorhizobium-specific phages. Arrows indicate the transcriptional orientation of the genes. P1 and P2 indicate promoters. The plot shows the GC content of the ΦLM21 sequence (mean value of 60.6%). The graphical representation of the proteome comparative analyses of ΦLM21 and other Sinorhizobium phages (16-3, PBC5, and ΦM12) is shown below the linear map of ΦLM21 along with two putative prophage sequences of Sinorhizobium meliloti Rm41 (positions 741832 to 794129; accession number HE995405), named Rm41 prophage, and S. meliloti AK83 (positions 794767 to 844536; CP002781), named AK83 prophage. White, gray, and black circles indicate the presence of homologous proteins with levels of amino acid identity ranging between 20 and 49% (white circles), 50 and 74% (gray), 75 and 100% (black).
