Abstract
The taxonomic and evolutionary relationships between Porphyra of the boreal North Pacific (NP) and North Atlantic (NA) are being examined using near full length sequences of rbcL and the rbcL rbcS spacer (∼1420 bp). Phylogenetic analysis openface> 20 recognized species produced clusters containing both NP and NA species: Porphyra carolinenesis (NA) and Porphyra perforata (NP); Porphyra. leucosticta (NA) and Porphyra fucicola (NP); Porphyra‘amplissima’ (NA) and Porphyra cuneiformis (NP); Porphyra‘umbilicalis’ (NA) and Porphyra mumfordii (NP). A cluster of NP species including Porphyra abbottae, Porphyra kurogii, Porphyra pseudolinearis, and Porphyra pseudolanceolata formed a sister clade to P. fucicola (NP), P. leucosticta (NA) and several cryptic NA taxa. These results demonstrate that a number of “independent” migrations occurred between the North Pacific and Northern Atlantic. Furthermore these results confirm the hypothesis, based on similarities in morphology, isozymes, and karyotype, of Lindstrom & Cole (1992), that several sibling species pairs exist for Porphyra of the boreal North Pacific (NP) and North Atlantic (NA).
