Characterization of the complete mitochondrial genome of Caryopemon giganteus Pic (Coleoptera: Chrysomelidae: Bruchinae).

ABSTRACT: We sequenced, assembled, and annotated the complete mitochondrial genome of the seed beetle Caryopemon giganteus, which represents the first report in the tribe Caryopemini from the subfamily Bruchinae of Chrysomelidae. The circular mitochondrial genome of the species contains 15,727 bases, 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a non-coding region. The GC content of the genome is 25.3%, which is higher than any other reported mitochondrial genomes within Bruchinae. The 16S ribosomal RNA gene and the 12S ribosomal RNA gene are 1284 and 835 bp in length, respectively. 12 PCGs started with the typical ATN codon, except for ND1 initiated with TTG. Five PCGs have the typical stop codon of TAA or TGA, while the remainder PCGs are terminated with incomplete stop codons (TA or T). The phylogenetic analysis based on a combination of 13 genes of the mitochondrial genomes of six species of Bruchinae and 23 species from other 10 subfamilies of Chrysomelidae recovered a generally well resolved and strongly supported tree topology, which shows that C. giganteus has the basalmost position in Bruchinae.

The complete mitochondrial genome of the seed-borer weevil, Bruchidius uberatus (Coleoptera: Chrysomelidae: Bruchinae).

Project description:In this study, the complete 15,892 bp mitochondrial genome of Bruchidius uberatus (Fåhraeus) was sequenced using Illumina NovaSeq6000 platform. The mitogenome is a double-stranded circular molecule of 15,892 bp in length with 22 transfer RNA genes, 13 protein-coding genes and two ribosomal RNA genes as in other insects. Twenty-five species from 8 subfamilies of Chrysomelidae were selected as ingroups and 3 species of Lamiinae as outgroups for phylogenetic analysis based on mitogenome. The results showed that the subfamily Bruchinae was monophyly. Genus Bruchidius had more closed relationship with Acanthoscelides than Callosobruchus in Bruchinae with high support values.

The complete mitochondrial genome of the cowpea weevil, Callosobruchus maculates (Coleoptera: Chrysomelidae: Bruchinae) and a related phylogenetic analysis of Chrysomelidae.

Project description:In this study, the complete 17,809?bp mitochondrial genome of Callosobruchus maculates (F.) (Coleoptera: Chrysomelidae: Bruchinae) was sequenced using Illumina's HiSeq2000 platform. The mitogenome is a double-stranded circular molecule of 17,809?bp in length with 21 transfer RNA genes, 13 protein-coding genes, and two ribosomal RNA genes as in other insects. Specially, there is a 2008?bp-inserted segment between ND2 and tRNA-Trp from 1180 to 3187, which cannot be aligned to any known gene of mitogenomes. To estimate the taxonomic status of Bruchinae, total 17 species from eight subfamilies of Chrysomelidae were selected as ingroups and three species of Lamiinae as outgroups for phylogenetic analysis based on mitogenome. The results showed that three major lineages were formed, including a basal 'Eumolpine' clade (Cassidinae, Eumolpinae, Cryptocephalinae, Clytrinae), ''Criocerine' clade (Criocerinae, Bruchinae) and 'Chrysomeline' clade (Chrysomelinae, Galerucinae s. l.). Bruchinae showed more closed relationship with Criocerinae than other subfamilies. More thorough taxon sampling will be needed to well understand the relationship in Chrysomelidae.

The complete mitochondrial genome of Monolepta hieroglyphica (Motschulsky) (Coleoptera: Chrysomelidae).

Project description:Monolepta hieroglyphica (Motschulsky) (Coleoptera: Chrysomelidae) is an important agricultural insect pest. In this study, the complete mitochondrial genome of M. hieroglyphica (GenBank accession number MW732714) was sequenced using Illumina HiSeq X Ten. The mitogenome was 16,213 bp long and comprised 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs) and a putative control region (CR). The nucleotide composition of the M. hieroglyphica mitochondrial genome was significantly biased (A, G, C and T accounted for 41.04%, 8.01%, 11.76% and 39.18%, respectively) with 80.23% A + T content. Two rRNAs were located between tRNA-Leu and the CR, separated by tRNA-Val. The CR, located between 12 s rRNA and tRNA-Ile, was 1,661 bp long. The length of the 22 tRNAs ranged from 61 to 71 bp. Phylogenetic analyses of 29 Chrysomelidae-Galerucinae species based on 13 mitochondrial protein-coding genes reconstructed using Bayesian 3.2.0 showed that the M. hieroglyphica mitogenome was clustered with the existing three different species of the Monolepta genus mitogenomes in a monophyletic manner. The M. hieroglyphica mitogenome provides an important data resource for further studies and contributes to our understanding of the phylogeny of this group.

All the 22 tRNAs have the typical cloverleaf secondary structure, except for trnS1 which lacked the dihydrouracil (DHU) arm. The phylogenetic relationship based on the neighbor-joining method showed that P. balyi is closely related to Agasicles hygrophila, which agrees with the conventional classification.

Complete mitochondrial genome of a leaf-mining beetle, Podagricomela nigricollis (Coleoptera: Chrysomelidae).

Project description:Podagricomela nigricollis is a citrus pest that distributes in South China. Currently, there was no complete mitochondrial genome of Podagricomela species available in GenBank. Here, we reported the complete circular mitogenome of P. nigricollis. It had a total length of 16,756 bp, including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one A + T-rich region. Among the 13 PCGs, only four (NAD5, NAD4, NAD4l, NAD1) located on the L-strand, whereas the other nine (NAD2, COX1, COX2, ATP8, ATP6, COX3, NAD3, NAD6, COB) located on the H-strand. Phylogenetic analysis using nucleotide sequences of the 13 PCGs indicated that P. nigricollis were clustered with six Galerucinae species, which was consistent with previous morphological classification.
