Genomic characteristics and environmental distributions of the uncultivated Far-T4 phages.

ABSTRACT: Viral metagenomics (viromics) is a tremendous tool to reveal viral taxonomic and functional diversity across ecosystems ranging from the human gut to the world's oceans. As with microbes however, there appear vast swaths of "dark matter" yet to be documented for viruses, even among relatively well-studied viral types. Here, we use viromics to explore the "Far-T4 phages" sequence space, a neighbor clade from the well-studied T4-like phages that was first detected through PCR study in seawater and subsequently identified in freshwater lakes through 454-sequenced viromes. To advance the description of these viruses beyond this single marker gene, we explore Far-T4 genome fragments assembled from two deeply-sequenced freshwater viromes. Single gene phylogenetic trees confirm that the Far-T4 ph
