FIG 2.

Phylogenetic tree of deep-sea fungal isolates (red) and 454 pyrotags (gray) obtained by analysis of SSU rRNA genes. The tree topology is based on maximum likelihood criteria and a ClustalW (version 1.83) alignment. Bootstrap values greater than 50% are shown at the nodes. Phylogenetic data of Ciobanu et al. (15) were integrated as 454 pyrotags. Mucor luteus (GenBank accession number FJ605511), which belongs to the phylum Glomeromycota, was used as an outgroup. Dark and light gray boxes, Basidiomycota and Ascomycota, respectively. OTU, operational taxonomic unit.
