Fig 6. Evolutionary relationship of the SPE-50 homologous proteins.

The proteins were identified from a BLASTP search of the NCBI non-redundant protein sequence database. For each protein, the accession number is listed before the slash, and the WormBase identifier after the slash. The duplication event that resulted in creation of the two paralogs occurred prior to the radiation of the species included in the analysis. The phylogeny of the species within Caenorhabditis follows Stevens et al. [36].
