Maximum likelihood (ML) tree of plastidal-encoded rbc L sequence of Paralia. The fragment used corresponded to a 540 bp barcode segment of the RuBisCo large subunit (rbcL). Stephanopyxis palmeriana is the outgroup; four clades of taxa are labelled I, II, III and IV with bootstrap support (ML/MP/NJ). Separation valve type is shown to the right of the terminal branches. The number in parentheses next to the taxon name represents the number of clones (or single chains in the case of P. fenestrata) used in construction of the tree if not all are shown (i.e., P. guyana ‘smooth’ genodeme and P. marina). Representative clones were selected based on methods used to generate Figure 10 (see text for explanation).
