The complete mitogenome of ‘Pingbancai’, an important economic Saccharina cultivation variety

Saccharina is one of the most important economic seaweed. We presented the complete mitogenome of Saccharina variety ‘Pingbancai’ (Saccharina japonica × latissima) in this work. Circular-mapping mitogenome was 37,658 bp in length with overall A + T content of 64.70%, encoding 3 rRNAs (23S, 16S and 5S), 25 tRNAs, 38 genes (including 3 open reading frames, ORFs). Gene arrangement and component of ‘Pingbancai’ mitogenome were identical to those Saccharina species and cultivation varieties, which show highly conservative evolution in mitochondrial genomes within Saccharina. The phylogenetic analysis based on mitogenomes showed that ‘Pingbancai’ had a closer evolutionary relationship with Saccharina japonica than Saccharina latissima and the supported mitogenome was maternally inherited.
