Abstract
The complete sequence (37 654 bp) of the mitochondrial DNA (mtDNA) of the Saccharina sp. ye-C12 was determined using Illumina sequencing data. The genome contains 38 protein-coding genes (PCG), three ribosomal RNA (rRNA), 25 transfer RNA (tRNA) genes and the phylogenetic analysis based on the mitochondrial genomes of brown algae indicated that Saccharina sp. ye-C12 and Saccharina japonica are the most closely related species, which strongly supports their close phylogenetic affinity.
