Phylogeny of chitinase clone sequences from September libraries. Alignments were made by using ClustalW, and clone sequences were aligned with known chitinase sequences taken from GenBank and Swissprot. Trees were drawn by using PHYLIP 3.5. Bootstrap values are based on 100 resamplings of the data set; values below 50 were removed from the tree. Bootstrap values for the neighbor-joining analysis are given above the node, and those for maximum-parsimony analysis are given below.
