    • Phylogenetic tree　Phylogenetic tree was constructed by maximum likelihood method using successive mitochondrial gene (cox1) and chloroplast genes (psbA and rbcL). Red and blue box shows Southern Hokkaido dulse and Atlantic dulse, respectively. Chloroplast genomes were similar between them, however, these species were genetically separated in this tree.

    • Mitochondrial genome structures　There are two different between Southern Hokkaido dulse and Atlantic dulse. One is intron size in ribosomal RNA large subunit. The other is the direction of two genes (orf43 and orf44) were opposite.


    • The amount of protein in Southern Hokkaido dulse contains about 40% of dry weight, which is higher than the Atlantic dulse and Palmaria mollis (Devaleraea mollis). We need to investigate in future studies whether the difference from growth condition or genetics.
