Neighbor-joining tree of COI sequences of the Gelidiales, Gracilariales and Halymeniales. Sequence diversity based on the COI mitochondrial marker for surveyed Rhodophyta specimens belonging to the orders Gelidiales, Gracilariales and Halymeniales. Neighbor-joining tree is based on the Maximum Composite Likelihood nucleotide model in MEGA 4.0. Scale bar = substitutions per site.
