FIG. 3.

Comparison of protein homologs to sediment viral concentrate RAPD-PCR sequences (112 of a total of 448 sequenced). Phage, phage-related, or near-phage sequences comprised 69% of the total. Values in parentheses are median log transformed E values. Results are based on tBLASTx E values (E < 0.001). Abbreviations are as follows: Bact, bacteria; Hyp, hypothetical gene; Fxn, gene with defined function; +P, within 60 kb of phage-related gene(s); −P, no close proximity to phage-related gene(s); +T, within 60 kb of transposon-related gene(s).
