The complete mitogenome of ‘Dongfang No.3’, an important Saccharina cultivar in China

摘要

In this work, the complete mitogenome of Saccharina cultivar ‘Dongfang No.3’ is reported. This mitogenome has a circular mapping organization with the length of 37,657?bp and contains 66 genes, including 35 protein-coding genes, three rRNAs, 25 tRNAs, and three open reading frames (orf s). The overall AT content is 64.73%, showing a higher AT content. The gene content and gene sequence are consistent with those reported varieties and cultivars of Saccharina . Chinese main Saccharina cultivars are analyzed by phylogenetic analysis. It indicates that ‘Dongfang No.3’ has a close relationship with Saccharina japonica , which strongly supports its genetic origin. The complete mitogenome analysis in this work would help in understanding the genetic background of Chinese Saccharina cultivars.
