Boore, J. L., & J. L. Staton. 2002. The mitochondrial genome of the
sipunculid Phascolopsis gouldii supports its association with Annelida
rather than Mollusca. - Molecular Biology and Evolution 19(2):127-137.
ABSTRACT: "We determined the sequence of about half (7,470 nt) of the
mitochondrial genome of the sipunculid Phascolopsis gouldii, the first
representative of this phylum to be so studied. All of the 19 identified genes
are transcribed from the same DNA strand. The arrangement of these
genes is remarkably similar to that of the oligochaete annelid Lumbricus
terrestris. Comparison of both the inferred amino acid sequences and the
gene arrangements of a variety of diverse metazoan taxa reveals that the
phylum Sipuncula is more closely related to Annelida than to Mollusca. This
requires reinterpretation of the homology of several embryological features
and of patterns of animal body plan evolution."
