Phylogeny of sequenced genes encoding GH6, GH7 and GH45 family proteins from the thermophilic fungi. All the genes sequenced in the present study except GH7 from R. miehei that was too short to produce any significant alignment and the genes found in NCBI (see Table 3) were aligned with MUSCLE before curating the alignments with Gblocks and building of phylogenetic trees with PhyML (Dereeper et al. 2008). The three were depicted with TreeDyn. O: Onygenales; S: Sordariales; E: Eurotiales; M: Mucorales. See Table 1 for abbreviations of fungal names.
