    Abstract

    Marine sponges have never been directly examined with respect to the presence of viruses or their potential involvement in horizontal gene transfer. Here we demonstrate for the first time, to our knowledge, the presence of viruses in the marine sponge Hymeniacidon perlevis. Moreover, bacterial 16S rDNA was detected in DNA isolated from these viruses, indicating that phage-derived transduction appears to occur in H. perlevis. Phylogenetic analysis revealed that bacterial 16S rDNA isolated from sponge-derived viral and total DNA differed significantly, indicating that not all species are equally involved in transduction.

    • The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequences from viral DNA retrieved from seawater and from H. perlevis in June 2010 are JQ435953–JQ435983 and JQ435984–JQ436010, respectively.
