Abstract
Here, the complete mitogenome of Petalonia binghamiae (J. Agardh) K. L. Vinogradova was determined and analyzed. The length of the complete P. binghamiae mitogenome was determined to be 37,460 bp. The mitogenome contains a set of 68 genes, including 35 protein-coding genes, 3 rRNA genes, 24 tRNA genes, 1 tRNA pseudogene, and 5 unidentified open reading frames (ORFs). The noncoding sequence constitutes 7.03% of the P. binghamiae mtDNA. Twenty-seven of the 35 (77.14%) protein-coding genes ended with a TAA stop codon, 6 (17.14%) with TAG, and 2 (5.71%) with TGA. All protein-coding genes in P. binghamiae were inferred to use the start codon ATG, except for nad11. The mitogenome phylogenetic analysis, based on 35 protein-coding genes, reveals that P. binghamia showed that P. binghamiae was clustered together with P. fascia. The complete mitochondrial genome sequence provided here would be useful for further understanding the evolution of Petalonia.
