The complete mitochondrial genome of the golden apple snail Pomacea canaliculata (Gastropoda: Ampullariidae)

Abstract

We present the complete mitochondrial genome of Cipangopaludina cathayensis in this study. The mitochondrial genome is 15 706 bp in length, containing 13 protein-coding genes, two rRNA genes and 22 tRNA genes. Overall nucleotide compositions of the light strand are 40.97% of A, 30.78% of T, 20.48% of C and 12.60% of G. Its gene arrangement and distribution are different from the typical vertebrates. The absence of D-loop is consistent with the Gastropoda, but, at least, one lengthy non-coding region is an essential regulatory element for the initiation of transcription and replication. A phylogenetic tree is constructed using the maximum-likelihood method based on the complete mitogenomes of the closely related 21 Gastropoda species to assess their actual phylogenetic relationship and evolution. The result provides fundamental data for resolving phylogenetic and genetic problems related to effective management strategies.

Complete mitochondrial genome of the apple snailPomacea diffusa(Gastropoda, Ampullariidae) with phylogenetic consideration

“…The overall nucleotide compositions of the light strand in descending order are 39.62% of A, 30.13% of T, 16.02% of C, and 14.24% of G. The most representative base is A, and the bias against G is observed. The absence of D-loop is consistent with the Gastropoda (Zeng et al 2015;Yang et al 2016aYang et al , 2016bYang et al , 2016c, but, at least, one lengthy non-coding region is an essential regulatory element for the initiation of transcription and replication (Wolstenholme 1992).…”

Piezoelectric effect in GaAs nanowires: experiment and theory

“…The theoretical value of PSCs in WZ NW is found and compared with the experimental data. PSCs cannot be straightforwardly computed by the Berry‐phase method , but they can be determined indirectly through the thermodynamic relationship of d to e vectors . As a result, the PSCs are calculated in (pC/N): d 13 = 1.13–1.2, d 33 = –2.2 to –2.35, d 15 = 3.27–3.47.…”

Comparative Characterization of the Complete Mitochondrial Genomes of the Three Apple Snails (Gastropoda: Ampullariidae) and the Phylogenetic Analyses

“…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 ].…”
