Phylogenetic tree based on <i>rbcL</i> sequences.

<p>Maximum likelihood (ML) phylogeny of the class Ulvophyceae based on 1254 nucleotide positions of the chloroplast-encoded <i>rbcL</i> gene. The phylogram of the entire tree on the upper left is colored to match the inset. <i>Chlamydomonas reinhardtii</i> (class Chlorophyceae) was chosen as the outgroup. Red, <i>rbcL</i> sequences from <i>P. ocellatus</i>. Black, algal <i>rbcL</i> sequences. Bootstrap support (BS) values >50% are provided at the nodes (neighbor-joining/ML). “-“, BS <50%; “NC”, nonconsensus node that was not observed in the neighbor-joining tree.
