Box plots show the percent amino acid (aa) identity for metagenomics reads (32 metagenomes, POV) recruiting to predicted genes from <i>Pseudoalteromonas</i> phage B8b as well as the abundant Pelagiphage HTV0C10P (GenBank No/ KC465898) and the non-marine Enterobacteriaphage T4 (GenBank No. NC_000866).

<p>Metagenomes were grouped in 6 categories product of the combination of photic zone and site location as appear in Hurwitz and Sullivan [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0114829#pone.0114829.ref025" target="_blank">25</a>]. A) Percentage of the genome that is being covered by the metagenomics reads. B) Percentage of reads that better align to ORFs in the indicated genome (as per bitscore comparison) than the rest of NR. In box plots boxes mark the upper and lower quartile with the median shown in red, whiskers are extended to 1.5 times the interquartile range, finally, red crosses show outliers.
