“…The total nucleotide length of the 13 PCGs in P. bilineatus is 10,839 bp in length, and most of the PCGs start with a typical ATN codon, except for the cox1 and atp8 genes, which start with TTG and GTG, an accepted canonical mitochondrial start codon for invertebrate mitogenomes [36,37,38,39]. The stop codons (TAA and TAG) are utilized in these PCGs.…”

The mitochondrial genome (mitogenome) can provide information for phylogenetic analyses and evolutionary biology. We first sequenced, annotated, and characterized the mitogenome of Philomycus bilineatus in this study. The complete mitogenome was 14,347 bp in length, containing 13 protein-coding genes (PCGs), 23 transfer RNA genes, two ribosomal RNA genes, and two non-coding regions (A + T-rich region). There were 15 overlap locations and 18 intergenic spacer regions found throughout the mitogenome of P. bilineatus. The A + T content in the mitogenome was 72.11%. All PCGs used a standard ATN as a start codon, with the exception of cytochrome c oxidase 1 (cox1) and ATP synthase F0 subunit 8 (atp8) with TTG and GTG. Additionally, TAA or TAG was identified as the typical stop codon. All transfer RNA (tRNA) genes had a typical clover-leaf structure, except for trnS1 (AGC), trnS2 (TCA), and trnK (TTT). A phylogenetic analysis with another 37 species of gastropods was performed using Bayesian inference, based on the amino acid sequences of 13 mitochondrial PCGs. The results indicated that P. bilineatus shares a close ancestry with Meghimatium bilineatum. It seems more appropriate to reclassify it as Arionoidea rather than Limacoidea, as previously thought. Our research may provide a new meaningful insight into the evolution of P. bilineatus.

“…Mitochondrial genes overlap and serve to compact the mitogenomes. Each of the snails possessed five overlap sites totaling 11 bp in P. canaliculata , 27 bp in P. diffusa and 13 bp in P. maculate similar to other mitogenomes [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ].…”

The apple snails Pomacea canaliculata, Pomacea diffusa and Pomacea maculate (Gastropoda: Caenogastropoda: Ampullariidae) are invasive pests causing massive economic losses and ecological damage. We sequenced and characterized the complete mitochondrial genomes of these snails to conduct phylogenetic analyses based on comparisons with the mitochondrial protein coding sequences of 47 Caenogastropoda species. The gene arrangements, distribution and content were canonically identical and consistent with typical Mollusca except for the tRNA-Gln absent in P. diffusa. An identifiable control region (d-loop) was absent. Bayesian phylogenetic analysis indicated that all the Ampullariidae species clustered on the same branch. The genus Pomacea clustered together and then with the genus Marisa. The orders Architaenioglossa and Sorbeoconcha clustered together and then with the order Hypsogastropoda. Furthermore, the intergenic and interspecific taxonomic positions were defined. Unexpectedly, Ceraesignum maximum, Dendropoma gregarium, Eualetes tulipa and Thylacodes squamigerus, traditionally classified in order Hypsogastropoda, were isolated from the order Hypsogastropoda in the most external branch of the Bayesian inference tree. The divergence times of the Caenogastropoda indicated that their evolutionary process covered four geological epochs that included the Quaternary, Neogene, Paleogene and Cretaceous periods. This study will facilitate further investigation of species identification to aid in the implementation of effective management and control strategies of these invasive species.

“…The codon alignment ATP6 for species E. maclovinus, N. coriiceps, C. rastrospinosus and C. aceratus show that GTG codes for methionine, as the start codon for the protein. GTG which is originally known for coding the amino acid valine has been accepted as a mitochondrion start codon for invertebrate mitogenomes [45][46][47]. A common feature with the species that have GTG as a start codon is that N. coriiceps, E. maclovinus, C. rastrospinosus have genes coding for myoglobin, where the latter is devoid of haemoglobin.…”

The Channichthyidae family (icefish) are the only known vertebrate species to be devoid of haemoglobin. Mitochondrial changes such as tight coupling of the mitochondria have facilitated sustained oxygen and respiratory activity in the fish. This makes it important to appreciate features in the sequence and structure of the proteins directly involved in proton transport, which could have physiological implications. ATP synthase subunit a (ATP6) and subunit 8 (ATP8) are proteins that function as part of the F0 component (proton pump) of the F0F1complex. Both are encoded by the mitochondrial genome and involved in oxidative phosphorylation. To explore mitochondrial sequence variation for ATP6 and ATP8 we have gathered sequences and predicted structures of these two proteins of fish from the Notothenioidei sub-order, a sub-Antarctic species. We compared these with seven other vertebrate species in order to reveal whether there might be physiologically important differences that can help us to understand the unique biology of the icefish.
