Column 1 is the site numbered according to genes from Crypthecodinium cohnii (cox1) or Pfiesteria piscicida (cob). Column 2 and 3 are pre-edited and post-edited states in D. baltica. Column 4 is the position within the codon. Column 5 is the amino acid change. Column 6 lists other dinoflagellates where the same editing is found. Abbreviations: Pp, Pfiesteria piscicida; Cc, Crypthecodinium cohnii; Pmic, Prorocentrum micans; Prorocentrum minimum; Km, Karlodinium micrum; Ps, Pfiesteria shumwyae; At, Alexandrium tamarense.

1 This change is absent in Pp and Cc.

2 These changes are absent in Pp and not sampled from Cc.
