Supplemental Figure 1. The sequence variations in the MtDNA segments of seven Japanese and North American isolates containing MtORFvar. from A hypervariable mitochondrial protein coding sequence associated with geographical origin in a cosmopolitan bloom-forming alga, <i>Heterosigma akashiwo</i>

Sequence differences compared to NEPCC522 in each of the other strains are highlighted with red, blue, and green. A nucleotide deletion in strain Y is marked with a green triangle.
