Figure 1.

FootPrinter identified 12 highly conserved motifs in the metallothionein gene family. Each input sequence is the 590 bp located upstream of the start codon. For more details on each motif, see Table 1. The phylogenetic tree is derived from Binz and Kägi (1997; branch lengths not to scale). Numbers along branches indicate when each motif was created (unboxed) or lost (boxed), ignoring any less conserved occurrences of the motif not reported by FootPrinter.
