Complete mitogenome of the cutlassfish Trichiurus haumela (Scombriformes: Trichiuridae) from Ningde, Fujian province, Southeast China

Abstract

The cutlassfish, Trichiurus haumela (Scombriformes: Trichiuridae), is well adapted to benthopelagic life with high commercial value in the world. In this study, mitogenome of this species was assembled with high coverage using Illumina sequencing data and the 16,855 bp length was acquired. The base composition is 28.75% for A, 29.33% for C, 16.14% for G, and 25.78% for T. The mitogenome includes 13 protein-coding genes, 21 transfer RNA, and two ribosomal RNA genes. The phylogeny showed that it is closely related to Trichiurus japonicus with high bootstrap value supported. The complete mitogenome of T. haumela can provide essential DNA molecular data for further phylogenetic and evolutionary analysis.

Complete mitogenomes of four Trichiurus species: A taxonomic review of the T. lepturus species complex

“…3), the sequences of the genus Trichiurus were grouped into five lineages (I-V). Trichiurus haumela (MH846121 in Zheng et al 2019) was included within T. japonicus (lineage I), and T. lepturus (MW719078) in our study and "T. lepturus" (MK333401 in Mukundan et al 2020) were not considered monophyletic (lineages II and III). Thus, our study used COI sequences to examine the taxonomic status of Trichiurus species.…”

“…The remaining high-quality reads were assembled using SPAdes v3.10 (https://github.com/ablab/spades). Compared with the corresponding complete mitogenome sequences of the genus Trichiurus (Liu and Cui 2009;Liu et al 2013;Xu et al 2019;Zheng et al 2019;Mukundan et al 2020; Table 1), protein-coding genes (PCGs), tRNA-coding genes and ribosome-coding genes were identified by BLAST. Codon usage, nucleotide substitution and base composition were determined using MEGA-X and DnaSP version 5.10 (Librado and Rozas 2009), and the rules for the vertebrate mitochondrial genetic code was used.…”

“…Many studies have suggested that Clupea haumela Fabricius, 1775 is a synonym of T. lepturus Parin 1993, 2021;Fricke 2008;Golani and Fricke 2018); however, a recently published study (Zheng et al 2019) mentioned this species as a valid Trichiurus species without taxonomic evidence and presented its complete mitochondrial genome. In addition, many studies (Tucker 1956;Nakamura and Parin 1993;Nelson 1994) suggested that T. japonicus Temminck & Schlegel, 1844 is synonymous with T. lepturus, but other studies (Lee et al 1977;Nakabo 2000;Chakraborty et al 2006a, b;Tzeng et al 2007;Hsu et al 2009;He et al 2014;Fricke et al 2021) suggested that T. japonicus is a valid species.…”

The complete mitogenome of the Lepturacanthus savala (Perciformes: Trichiuridae) from the Yellow Sea

“… 2019 ; Zheng et al. 2019 ). Most of the genes are transcribed on the heavy strand (H-strand), except for seven tRNA genes (Gln, Ala, Asn, Cys, Tyr, Ser-UGA, Glu).…”

“…Different with typical 22 tRNA genes in vertebrate mitogenome, the mitogenome contained 21 tRNA genes except for tRNA Pro . The tRNA Pro gene is absent also in T. japonicus and T. nanhaiensis (Liu and Cui 2009;Liu et al 2013;Xu et al 2019;Zheng et al 2019). Most of the genes are transcribed on the heavy strand (H-strand), except for seven tRNA genes (Gln, Ala, Asn, Cys, Tyr, Ser-UGA, Glu).…”
