The complete mitochondrial genome (mitogenome) of a red alga, Pyropia haitanensis Chang et Zheng, a circular-mapping molecule, was determined to be 37,023 bp. The overall AT content of the mitogenome is 69.32%. It contains 54 genes, including 49 conserved genes, 4 intronic reading frames, and an additional free-standing open reading frame. The rnl gene and cox1 gene are the only two interrupted genes in the mitogenome. All the protein-coding genes and Open Reading Frames (ORF) have typical ATG start codon, except for cox1 and cox2, which contain the unusual GTG and CTG as an initiator codon, respectively. Relative differences are found by comparing the mitogenome of P. haitanensis with that of Porphyra purpurea, reinforcing the viewpoint that the two species belong to different genus.
坛紫菜（Pyropia haitanensis Chang et Zheng）的完整线粒体基因组（线粒体基因组）是一个环状分子，其长度为37,023 bp。该线粒体基因组的总体AT含量为69.32%。它包含54个基因，其中包括49个保守基因、4个内含子阅读框和一个额外的独立开放阅读框。rnl基因和cox1基因是线粒体基因组中仅有的两个中断基因。除cox1和cox2分别含有不寻常的GTG和CTG作为起始密码子外，所有蛋白质编码基因和开放阅读框（ORF）都有典型的ATG起始密码子。通过比较坛紫菜与紫菜（Porphyra purpurea）的线粒体基因组发现了相对差异，这强化了这两个物种属于不同属的观点。
