Figure 2. Maximum likelihood analysis of chloroplast genomes (a), rbcL sequences (b), mitochondrial genomes (c), and CO1 sequences (d) of Pyropia and Porphyra.

Numbers above branches are maximum likelihood bootstrap values based on 1,000 replicates. The legend below represents the scale for nucleotide substitutions. The analysis was performed using RAxML and the default parameters in Galaxy⁴³,⁴⁴,⁴⁵. The tree was constructed with TreeDyn 198.3 at Phylogeny.fr⁴⁶.
