‘Total evidence’ refutes the inclusion of Perkinsus species in the phylum Apicomplexa
The phylogenetic affinities of the oyster pathogen Perkinsus marinus were investigated with morphology, 18S-like rDNA data and actin sequence data. Morphological investigations revealed that Perkinsus species do not have a conoid and that other criteria which have been used to place them in the Apic...

| description | The phylogenetic affinities of the oyster pathogen Perkinsus
marinus were investigated with morphology, 18S-like rDNA
data and actin sequence data. Morphological investigations revealed that
Perkinsus species do not have a conoid and that
other criteria which have been used to place them in the Apicomplexa are
general to alveolates. When considered separately,
18S-like rDNA and actin data sets each support a closer affinity for
Perkinsus marinus with the dinoflagellates. However,
each of these separate analyses possess their own biases and weaknesses.
Use of the phylogenetic principle of ‘total
evidence’ in which data sets are combined in simultaneous analysis
yielded a more robust hypothesis that is stable both
to character and taxonomic sampling. The resulting cladogram strongly
corroborates the placement of Perkinsus species
with the Dinoflagellida and not with the Apicomplexa. |
