FIG. 5.

Phylogenetic relationships among OCS and OM clones related to the Prasinophyceae II lineage. The phylogenetic tree was constructed by the maximum-likelihood method (fastDNAml [43]). This analysis included a mask of 382 nucleotides (nucl.), corresponding to the 5′ end of the plastid SSU rRNA gene. Bootstrap replications (100 resamplings) were performed by distance (above each node) and maximum-parsimony (below each node) methods. Bootstrap values of <50% are not shown. Chloroplast (cp) SSU rRNA sequences from charophytes, a Chara sp. and Klebsormidium flaccidum, were used to root the tree.
