The mitochondrial genome of Apion squamigerum (Coleoptera, Curculionoidea, Brentidae) and the phylogenetic implications.

ABSTRACT: In this article, we present the nearly complete mitochondrial genome (mitogenome) of the weevil beetle Apion squamigerum (Curculionoidea, Brentidae), assembled using data from Illumina next generation sequencing (NGS). This mitogenome was found to be very large, with the total length of 18,562 bp. Two trnM genes were identified. A large non-coding intergenic spacer spanning 1,949 bp occurred between trnI and trnM2. Combined with 111 existing weevil mitogenomes, we conducted phylogenetic reconstructions based on various datasets under maximum likelihood and Bayesian inference. Firstly, phylogenetic analyses robustly supported a sister group of A. squamigerum and Rhopalapion longirostre, namely, that two species of Apioninae (Brentidae) formed a clade. Within the entire Curculionoidea, the Nemonychidae diverged firstly, following the families Anthribidae and Attelabidae. In addition, a large clade comprising the sister families Brentidae and Curculionidae was strongly supported in all trees.

First Complete Mitochondrial Genome of Melyridae (Coleoptera, Cleroidea): Genome Description and Phylogenetic Implications.

Project description:To explore the characteristics of the mitogenome of Melyridae and reveal phylogenetic relationships, the mitogenome of Cordylepherus sp. was sequenced and annotated. This is the first time a complete mitochondrial genome has beengenerated in this family. Consistent with previous observations of Cleroidea species, the mitogenome of Cordylepherus sp. is highly conserved in gene size, organization and codon usage, and secondary structures oftRNAs. All protein-coding genes(PCGs) initiate withthe standard start codon ATN,except ND1, which starts with TTG, and terminate with the complete stop codons of TAA and TAG, or incomplete forms, TA- and T-. MosttRNAs have the typical clover-leaf structure, except trnS1 (Ser, AGN), whose dihydrouridine (DHU) armis reduced. In the A+T-rich region, three types of tandem repeat sequence units are found, including a 115 bp sequence tandemly repeated twice, a 16 bp sequence tandemly repeated three timeswith a partial third repeat and a 10 bp sequence tandemly repeated seven times. Phylogenetic analyses based on 13 protein-coding genes by both Bayesian inference (BI) and maximum likelihood (ML) methods suggest that Melyridae sensu lato is polyphyletic, and Dasytinae and Malchiinae are supported as independent families.

The complete mitochondrial genome of Lixus subtilis Boheman, 1835 (Coleoptera, Curculionidae) and its phylogenetic implications.

Project description:The first complete mitochondrial genome of Lixus subtilis Boheman is reported in this study. The circular genome is 15,223 bp long, including a standard set of 21 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), 13 protein-coding genes, and a non-coding control region. The trnI gene was not found in the L. subtilis mitogenome. All tRNAs had the typical cloverleaf structure, except for trnS1, which lacked the dihydrouridine arm. The phylogenetic tree of 13 Curculionidae species based on the concatenated nucleotide sequences of complete mitochondrial genomes strongly supported that L. subtilis is closely related to Curculioninae and Molytinae.

The complete mitochondrial genome of Philus pallescens Bates, 1866 (Coleoptera: Vesperidae) and its phylogenetic implications.

Project description:We sequenced and assembled the complete mitochondrial genome of Philus pallescens from Madou, Tainan County, Taiwan. The complete mitogenome of P. pallescens is 15,750 bp long, and contains 13 protein-coding, 22 tRNA and two rDNA genes. Nucleotide compositions of the mitogenome of P. pallescens are A: 38.08%, T: 32.25%, C: 18.67%, and G: 11.00%. The AT and GC skewness of the mitogenome sequence were 0.0828 and -0.25845 respectively, showing the genome composition skewed toward adenine and cytosine. The phylogenetic position of Chrysomelidae is sister to all the other families in the superfamily Chrysomeloidea. The results indicate that Chrysomeloidea Cerambycidae is not a monophyletic group. Philus is phylogenetically close to Spiniphilus. Vesperidae is monophyletic and sister to Disteniidae. Mitogenomic data from this study will provide useful information for further studies on the population genetics, speciation, and pest management of P. pallescens.

Characterization of the Complete Mitochondrial Genome of Epicauta impressicornis (Coleoptera: Meloidae) and Its Phylogenetic Implications for the Infraorder Cucujiformia.

Project description:The complete mitochondrial genome (mitogenome) of Epicauta impressicornis Pic (Coleoptera: Meloidae) was determined. The circular genome is 15,713-bp long, and encodes 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region (CR). The 13 PCGs start with the typical ATN codon and terminate with the typical stop codon TAA (ND2, ND4L, ND6, ATP6, ATP8, and CYTB), TAG (ND1 and ND3), and T- (COX1, COX2, COX3, ND4, and ND5). The two rRNA genes (rrn12S and rrn16S) are encoded on the minority strand. All tRNAs genes except trnS1 (AGN) are predicted to fold into the typical cloverleaf structure. The longest overlap (10 bp) is observed between ATP8 and ATP6. CR mainly harbors a conserved poly-T stretch (15 bp), a short repeat unit (17 bp), some universal microsatellite-like repeats, and a canonical poly-A tail. Phylogenetic analysis using Bayesian inferences and maximum likelihood based on nucleotide and corresponding amino acid sequences of the 13 PCGs showed that E. impressicornis is closely related to E. chinensis, this relationship is and supported within Cucujiformia belonging to Meloidae (Tenebrionoidea). Our results further confirmed the monophyly of Tenebrionoidea, Lymexyloidea, Curculionoidea, Chrysomeloidea, Cucujoidea, Coccinelloidea, and Cleroidea within Cucujiformia, and revealed the sister relationships of (Cleroidea + Coccinelloidea), (Lymexyloidea + Tenebrionoidea), and ((Chrysomeloidea + Cucujoidea) + Curculionoidea). We believe that the complete mitogenome of E. impressicornis will contribute to further studies on molecular bases for the classification and phylogeny of Meloidae or even Cucujiformia.

Characterization of the complete mitochondrial genome of Abscondita cerata (Olivier, 1911) (Coleoptera: Lampyridae) and its phylogenetic implications.

Project description:We sequenced and assembled the complete mitochondrial genome of Abscondita cerata from Nankang, Taipei City, Taiwan. The complete mitogenome of A. cerata is 16,964 bp long, and contains 13 protein-coding, 22 tRNA, and two rDNA genes. Nucleotide compositions of the mitogenome of the A. cerata are A: 43.93%, T: 36.74%, C: 11.05%, and G: 8.28%. The AT and GC skewness of the mitogenome sequence are 0.0891 and -0.1434, showing the genome composition skewness toward adenine and cytosine. The clade including all Lampyridae species is well supported. The result indicates that Luciolinae is a monophyletic group but Lampyrinae is not a monophyletic group, as Lamprigera yunnana, which was originally classified into Lampyrinae, is sister to Luciolinae. The genus Lamprigera may share a unique phylogenetic position in Lampyridae. The genus Luciola is a polyphyletic group and the genus Abscondita is a monophyletic group. A. cerata is the sister species to A. chinensis in China. Mitogenomic data from this study will provide useful molecular markers for further studies on the population genetics, speciation, and conservation of endemic species A. cerata in Taiwan.

Characterization of the complete mitochondrial genome of Euwallacea fornicatus (Eichhoff, 1868) (Coleoptera: Curculionidae: Scolytinae) and its phylogenetic implications.

Project description:In the present report, we described the complete mitochondrial genome of Euwallacea fornicatus from Sindien, New Taipei City, Taiwan. The length of the complete mitogenome of E. fornicatus is 15,743 bp and the mitogenome contains 13 protein-coding, 22 tRNA and two rDNA genes. Nucleotide compositions of the whole mitogenome are 39.41% for A, 33.84% for T, 16.64% for C, and 10.11% for G. The AT and GC skewness of mitogenome sequence was 0.076 and -0.244, showing the A-skew and C-skew. The reconstructed phylogenetic relationships of 33 Curculionid species based on 13 mitochondrial protein-coding genes received absolute support (100%). Euwallacea fornicates is sister to the rest species in Xyleborini. The phylogenetic position of Scolytinae is sister to the clade including Cucurlioninae, Molytinae and Cryptorhynchinae. Mitogenomic data from this study will provide useful information for further studies for the population genetics, invasive history and pest control of E. fornicatus in the future.

The complete mitochondrial genome of Coccotorusbeijingensis Lin et Li, 1990 (Coleoptera, Curculionidae, Curculioninae, Anthonomini) and its phylogenetic implications.

Project description:Coccotorusbeijingensis Lin et Li, 1990 belongs to Coleoptera, Curculionidae, Curculioninae, Anthonomini. It is a herbivorous insect that damages Celtisbungeana Blume (Ulmaceae) by affecting branch growth. The mitochondrial genome of C.beijingensis was sequenced and annotated to better identify C.beijingensis and related species. The total length of the C.beijingensis mitochondrial genome was 17,071 bp, contained 37 typical genes (13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes) and two control regions (total length: 2,292 bp). Mitochondrial genome composition, nucleotide composition and codon usage are similar to those of other sequenced Curculionidae mitogenomes. All protein-coding genes initiated with ATN and TTG codons and ended with TAA, TAG or incomplete stop codons (TA, T). In addition, analyses of pairwise genetic distances between individual PCGs in Curculionidae species showed that ATP8 was the least conserved gene, while COI was the most conserved. Twenty-one transfer RNAs had typical cloverleaf structures, while trnS1 lacked dihydrouridine (DHU) arms. ML and BI analyses, based on 13 PCGs and two rRNAs from ten species of Curculionidae, strongly support the relationships between C.beijingensis and species of the genus Anthonomus: ((An.eugenii+ An.rubi) + C.beijingensis + (An.pomorum+ An.rectirostris)) (BS = 100; PP = 1). Our phylogenetic analyses could mean that the genus Coccotorus should be sunk under Anthonomus, but more taxon sampling is needed to verify this result.

The complete mitochondrial genome of Meloeproscarabaeus (Coleoptera, Meloidae): genome descriptions and phylogenetic inferences.

Project description:Oil beetles are meloids, which are characterised for their cleptoparasitic habits in bee nests and oily fluid of cantharidin that causes blistering and swelling of the skin. The complete mitochondrial genome of Meloeproscarabaeus is determined using the next-generation sequencing technology and its genomic characteristics are described. The 15,653-bp long genome is a circular molecule consisting of 13 protein-coding genes (PCG), 22 transport RNA, two ribosomal RNA, and a control region. The A + T bias of the mitochondrial genome is manifested in the complete sequence and the codon usage of protein-coding genes. The genetic distance within and between genera is calculated to confirm the taxonomic status of M.proscarabaeus. The phylogenetic relationships among 15 available meloid taxa are inferred by the maximum likelihood (ML) method based on 13 mitochondrial PCGs. The ML trees resulting from nucleotide and amino acid datasets recover both the monophyly of Meloe and Epicauta and the polyphyly comprising Hycleus and Mylabris. This study provides the first description of a mitochondrial genome belonging to the genus Meloe. The mitochondrial genome sequence and its characteristics are expected to be conducive to future studies on taxonomy, systematics, and molecular phylogenetics of the family Meloidae.

Structural Features and Phylogenetic Implications of Three New Mitochondrial Genomes of Blister Beetles (Coleoptera: Meloidae).

Project description:The mitochondrial genome sequences of Denierella emmerichi, Epicauta curvispina, and Meloe poggii were determined. Their mitochondrial genomes were found to contain 37 genes (13 protein-coding genes [PCGs], 22 tRNA genes, and 2 rRNAs), of which 4 PCGs, 8 tRNA genes, and 2 rRNAs are encoded by the N-strand, and the remaining genes are encoded by the J-strand. The mitochondrial genomes of D. emmerichi, E. curvispina, and M. poggii are 15,702 bp, 15,813 bp, and 15,626 bp in length, respectively, and their guanine-cytosine contents are 28%, 33%, and 36%, respectively. The 13 PCGs of D. emmerichi, E. curvispina, and M. poggii use ATN as the standard start codon and TAA, TAG, and T as the stop codons. The Bayesian inference and maximum likelihood phylogenetic analysis results based on the 13 PCGs and 13 PCGs + 2rRNAs datasets of the mitochondrial genomes of the Meloidae support Epicauta (Coleoptera: Meloidae) ([D. emmerichi, E. curvispina, E. ruficeps, E. aptera] + [E. chinensis, E. impressicornis, E. gorhami, E. tibialis]). We believe that this research enriches the literature on the mitochondrial genomics of Meloidae and serves as a foundation for the further study of the phylogenetic relationships and characterization of Meloidae and Coleoptera.
