phylogeography of the northern atlantic species chondrus crispus gigartinales rhodophyta inferred from nuclear rdna internal transcribed spacer sequences
Hydrobiologia, 2007Co-Authors: Xiaoqi Zeng, Alan T Critchley, Steve L Morrell, Delin DuanAbstract:Eighteen isolates of the red algae Chondrus crispus were collected from Northern Atlantic sites, together with C. ocellatus, C. yendoi and C. pinnulatus from the North Pacific. The nuclear rDNA internal transcribed spacer (ITS) was sequenced and compared, spanning both the ITS regions and the 5.8S rRNA gene. Percentage of nucleotide variation for C. crispus ranged from 0.3% to 4.0%. Phylogenetic analyses were performed using maximum parsimony (MP), neighbor-joining (NJ) and minimum evolution methods. They showed that two main clades existed within the C. crispus samples examined and that suggested C. crispus had a single Atlantic origin. The clustering however did not follow the geographic origin. We hypothesized that the current distribution of C. crispus populations might be a result of three main factors: temperature boundaries, paleoclimate and Paleoceanography. ITS data exhibited abundant molecular information not only for phylogeographical investigation but also for systematics studies.
