2019) The first mitochondrial genome of Megabalanustintinnabulum (Sessilia: Balanidae) from China: phylogeny within Cirripedia based on mitochondrial genes, Mitochondrial DNA Part B, 4:2, 4016-4018, ABSTRACTHere we present the complete mitochondrial genome of Megabalanus tintinnabulum. The genome is 15,107 bp in length with a 67.35% AT content. It contains 13 protein-coding genes (PCGs), 2 rRNAs genes, and 22 tRNAs. Both rRNAs are encoded on the light strand, as in the other crustacean and barnacle mitochondrial genomes. Besides five tRNAs are encoded on the light strand (nad1, trnV, trnL1, trnC, trnQ, and trnK). Only one PCG is encoded on the light strand (nad1), whereas the other 12 PCGs are located on the heavy strand, which is consistent with M. ajax. Phylogenetic analysis based on mitochondrial PCGs shows that M. tintinnabulum is clustered with M. ajax into a branch (BP ¼ 100), and the group with M. volcano with high support. This study contributes to further phylogenetic analysis within Cirripedia.
