The complete mitogenome of Saccharina cultivar 'Xinbenniu' (Saccharina japonica xlatissima) and phylogenetic analysis

Here, the complete mitogenome of Saccharina cultivar 'Xinbenniu' was reported. It had a circular mapping organization with a length of 37,657 bp and contained 35 protein-encoding genes, 25 transfer RNA genes (tRNAs), 3 ribosomal RNA genes (rRNAs), and 3 open reading frames (ORFs). Moreover, overall, AT content was 64.70%. The gene content and encoding order were consistent with other reported Saccharina species and cultivars. Mitogenome phylogenetic tree showed that 'Xinbenniu' firstly clustered together with 'Pingbancai' and 'Ailunwan' indicating their closer relationship. The complete mitogenome analysis in this work would help in understanding the genetic background of Chinese Saccharina cultivars.
