The first mitochondrial genome of Callithamnion corymbosum (Smith) Lyngbye 1819

In this study, the complete mitochondrial genome of Callithamnion corymbosum (Smith) Lyngbye 1819 was reported for the first time, which could be beneficial for systematic studies on Callithamnion. The complete mitochondrial genome was 25,462 bp in length and contained 48 genes including 23 protein-coding, two rRNA, and 23 tRNA genes. The phylogenetic analysis based on the mitochondrial genome sequences revealed that all 16 Ceramiales species grouped into three distinct clades, and C. corymbosum of this study forms a independent clade, showing a unique status within the order Ceramiales.
