ML and Bayesian phylogenetic tree of the Chlorophyceae constructed by using 58 protein-coding genes of the chloroplast genomes. The concatenated nucleotide (nt) data set treated by three methods (partitioned by gene position, codon position and gene position without 3rd codon positions). The posterior probabilities (PP)/bootstrap support values (BP) above 50/0.50 are only shown on the key nodes. The tree was rooted with four species of the Ulvophyceae. Strains for chloroplast genomes investigated in this study are in bold
