Figure 2. Phylogenetic tree of GHF5. Numbered clones (for example SM2030B48) are cellulase genes identified in this study from the symbiotic protists of termites.

Letters in parentheses after each clone denote host termite species (Rs  =  Reticulitermes speratus, Nk  =  Neotermes koshunensis, Hs  =  Hodotermopsis sjostedti, Md  =  Mastotermes darwiniensis, Cp  =  Cryptocercus punctulatus). Accession numbers of reference sequences are denoted after species names. SF are indicated the sub-family (21) and SSFs are indicated sub-sub families that were used in Fig. 3. In sub-family 1 and 2, gray boxed sub-sub-family indicated that composed by symbiont's sequences and other sub-sub-families composed by bacterial sequences.
