Figure 7.

Phylogenetic analysis of MSMB-related genes in protostomes. Translated sequences spanning only from the N-terminus of the secreted protein to the last conserved cysteine residue were aligned. The unrooted tree was produced by the neighbor-joining method with 1000 replicates. Significant bootstrap values (> 70%) are shown in bold. * The sequence for "Mimulus lewisii" is presumed to represent a terrestrial gastropod (see text).
