Fig 7. A maximum likelihood phylogeny of nematode GH5 proteins. Orthologues of nematodes are represented using brown branches, and those of other species are shown as grey branches labeled with either green (bacteria) or blue (non-nematode eukaryotes) arcs.

Nematodes included in GH5_1 are Pristionchus pacificus (clade V). The phylogeny was computed using FastTree (as described in the Materials and Methods), and a high bootstrap support values of 0.91 reveals that GH5 orthologues of nematodes can be clearly distinguished from those of other eukaryotes and bacteria.
