Figure 1.
Phylogenetic analysis of 11 mitochondrial genomes with 15 protein-coding genes common to all strains, including eight haptophytes, two cryptomonads, and a diatom. Sequences were aligned with Clustal Omega (Sievers et al. 2011), prepared with GBlocks (Talavera and Castresana 2007), and concatenated to a length of 11,594 nucleotide positions. Tree construction was performed in MEGA-X with neighbor-joining and 1000 bootstrap replications. Units are substitutions per site and support values are indicated.
