Phylogenetic topology of rumen protozoan and bacterial glycoside hydrolases. A majority-ruled parsimony tree with maximum likelihood branch lengths was calculated using full-length amino acid sequences. Bootstrap values of 1,000 independent trees larger than 60 are labeled on each branch. Major clades are delimited by solid horizontal lines. Sequences identified in this study are shown in white in a black box. Protozoan sequences are shown in bold italics. GenBank accession numbers for each sequence are given within parentheses.
