We have reported the complete sequence of the DNA polymerase gene from the virus that infected a filamentous brown alga, Feldmannia sp. (FsV). The DNA polymerase gene from FsV encoded 986 amino acids and contained all the conserved motifs of 3′‐5′ exonuclease domains and catalytic domains found in B‐family (α‐like) DNA polymerases. The codons for the FsV DNA polymerase appeared to have some bias toward guanine/cytosine (G/C) in the third position. The phylogenetic analysis of the FsV DNA polymerase gene and other viral DNA polymerase genes indicated that FsV belongs to a family of algal viruses recently defined as Phycodnaviridae.
