Phylogenetic tree of the viral contigs based on the terminase large-subunit domains (A) and family B DNA polymerase (B) in the South China Sea viromes (SCSV) data set. The maximum likelihood phylogenetic trees of the Caudovirals terminase large-subunit domains (PF03237, A) and family B DNA polymerase (B) are shown (1000 iterations, JTT + G model). Only bootstrap values >50% are indicated at the nodes of the tree, and bootstrap scores greater than 90% are indicated with a black dot. The original terminase and family B DNA polymerase sequences from the surface viromes in the SCSV are indicated by wathet blue, and the original sequences from the deep sea viromes in the SCSV are in dark blue. Reference sequences are marked (see color legend at the bottom).
