Fig. 12. Phylogenetic relationships of the vertebrate MyoD sequences published to
date. Note that the cod sequence clusters with the seabream MyoD2 sequence.
Similarities are also evident in the in situ expression patterns. The
tree was constructed in PHYLIP
(Felsenstein 1995) by the
neighbour-joining method. Node numbers refer to the percentage of bootstrap
trials supporting a clade. Bootstrap confidence is based on 1000
pseudoreplications. The amino acid sequence for the single myogenic factor
(AMD1) of the ascidian Halocynthia roretzi (accession no. D13507) was
used as the outgroup. Other accession numbers are seabream Sparus
