FIG. 3.

Phylogenetic analysis of Cry proteins. Neighbor-joining phylograms were constructed after sequence alignment of the deduced amino acid sequences of selected known toxins and protein fragments corresponding to partial DNA sequenced fragments from FCC4, FCC7, and FCC41 by using the CLUSTAL X program and a BLOSSUM matrix. The tree was generated by using TREEVIEW. Sequences were obtained from the databases of the National Center for Biotechnology Information. The arrows indicate the positions of three novel Cry sequences. The positions of amino acid sequences deduced from known cry genes used in the analysis are indicated by asterisks. Numbers at nodes represent the percentages of bootstrap resamplings based on 1,000 replicates.
