Mitochondrial genome of Chrysochares punctatus (Coleoptera: Chrysomelidae: Eumolpinae) and phylogenetic analysis.

ABSTRACT: Here, we determined the nearly complete mitochondrial genome (mitogenome) of Chrysochares punctatus (Coleoptera: Chrysomelidae: Eumolpinae), an important insect pest on Apocynum venetum in Northwestern China. This mitogenome was 14,451 bp long, encoding 13 protein-coding genes (PCGs), 21 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes. The C. punctatus mitogenome presented an A + T content of 75.11%, with a positive AT-skew (0.064) and a negative GC-skew (-0.192). Ten PCGs started with a typical ATN codon, whereas the remaining three PCGs started with AAC (cox1) and TTG (nad1 and nad2). All tRNAs had a typical secondary cloverleaf structure, except for trnS1 which lacked the dihydrouridine arm. Bayesian phylogenetic analysis based on the nucleotide sequences of 13 PCGs recovered a phylogeny within Chrysomelidae: (((Chrysomelinae + Galerucinae), (((Eumolpinae, Lamprosomatinae), Cassidinae), Criocerinae)), Bruchinae).

The complete mitochondrial genome of Colasposoma dauricum auripenne (Motschlsky, 1860) (Coleoptera: Chrysomelidae: Eumolpinae).

Project description:The sweet potato leaf beetle Colasposoma dauricum auripenne (Motschlsky, 1860) (Coleoptera: Chrysomelidae: Eumolpinae) is one of the main pests in sweet potato. In this study, the complete mitochondrial genome of Colasposoma dauricum auripenne (Motschlsky, 1860) (Coleoptera: Chrysomelidae: Eumolpinae) has been sequenced. The mitogenome length is 15,614 bp (GenBank: MW528208), which includes 13 typical insect protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNAs), and 22 transfer RNA genes (tRNAs), and it contains 78.6% A + T and 21.4% G + C. All PCGs start with ATD (ATT, ATA, ATG) codon and stop with termination codon TAA, TAG and single T. The phylogenetic tree showed that Colasposoma had been cluster together, and form a sister group relationship with Pseudocolaspis. The complete mitogenome of C. dauricum auripenne would help understand Chrysomelidae evolution.

The complete mitogenome of B. fulvipes (GenBank accession number MT627597) is 15,762 bp in size, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and a noncoding D-loop region. The D-loop region is located between 12S rRNA and tRNAIle . The base composition of the whole B. fulvipes mitogenome is 41.66% for A, 8.89% for G, 34.32% for T and 15.12% for C, with a high AT bias of 75.98%. The present data could contribute to further detailed phylogeographic analysis and comprehensive control of this banaba new pest.

Mitochondrial genome of Taiwania circumdata (Coleoptera: Chrysomelidae: Cassidinae) and phylogenetic analysis.

Project description:In this study we sequenced and annotated the nearly complete mitochondrial genome (mitogenome) of Taiwania circumdata (Coleoptera: Chrysomelidae: Cassidinae), an important insect pest on sweetpotato and water spinach in Southern China. This mitogenome was 13,546?bp long and encoded 13 protein-coding genes (PCGs), 19 transfer RNA genes (tRNAs) and 2 ribosomal RNA unit genes. The T. circumdata mitogenome with an A?+?T content of 77.9% presented a positive AT-skew (0.126) and a negative GC-skew (-0.160). Eleven PCGs started with a typical ATN codon, whereas the remaining two PCGs used TTG (nad1) and AAT (cox1) as the initial codon. All the 19 tRNAs had a typical secondary cloverleaf structure, except for trnS1 (AGN) which lacked the dihydrouridine arm. Phylogenetic analyses using Bayesian inference and maximum likelihood methods based on the concatenated nucleotide sequences of 13 PCGs recovered a phylogeny of Bruchinae+?((Galerucinae?+?Chrysomelinae)?+?(Criocerinae?+?Cassidinae)). In Cassidinae, T. circumdata and Laccoptera ruginosa formed a clade, which was sister to three Cassida species.

Mitochondrial genome of Monolepta hieroglyphica (Coleoptera: Chrysomeloidea: Chrysomelidae) and phylogenetic analysis.

Project description:Monolepta hieroglyphica (Motschulsky, 1858) is a major pest of potato, maize, cotton and sorghum in China. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of M. hieroglyphica. This mitogenome was 15,761 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and two ribosomal RNA unit genes (rRNAs). Gene order was conserved and identical to most other previously sequenced Galerucinae Most PCGs of M. hieroglyphica have the conventional start codons ATN (six ATT, five ATG and one ATC), with the exception of nad1 (TTG). Except for three genes (cox1, nad4 and nad5) end with the incomplete stop codon T--, all other PCGs terminated with the stop codon TAA or TAG. The whole mitogenome exhibited heavy AT nucleotide bias (80.0%). Phylogenetic analysis positioned M. hieroglyphica in a well-supported clade within the subfamily Galerucinae with Monolepta occifluvis, Monolepta sp. and Paleosepharia posticata. These results provided an important basis for further studies on mitochondrial genome and phylogenetics of Galerucinae.

Mitochondrial genome and phylogenetic analysis of Psylliodes punctifrons Baly (Coleoptera: Chrysomelidae: Galerucinae).

Project description:We sequenced and annotated mitochondrial genome (mitogenome) of oilseed rape pest Psylliodes punctifrons Baly for the first time. The mitogenome is 15,611 bp, and the nucleotide composition of 37 genes is highly A + T biased (A: 34.2, C: 11.6, G: 12.1, and T:42.1). All PCGs start with ATN and stop with TAR, except COX3 and ND4 that stop with incomplete codon T-. The phylogenetic tree confirms that P. punctifrons is clustered with other Psylliodes species. This study enriches the mitogenomes of agricultural pests.

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.

Complete mitochondrial genome of a leaf-mining beetle, Rhadinosa nigrocyanea (Coleoptera: Chrysomelidae) with phylogenetic consideration.

Project description:The complete circular mitochondrial genome (mitogenome) of Rhadinosa nigrocyanea was 17,965?bp in length, which contained 2 ribosomal RNA genes, 22 transfer RNAs, 13 protein-coding genes (PCGs) and 1 non-coding AT-rich region with the length of 3002?bp. All of the 22 tRNA genes displayed a typical clover-leaf structure, with the exception of tRNASer (TCT). 12 PCGs were initiated by ATN codons, except for ND1 started with TTG. Only six PCGs used the typical stop codon 'TAA' and 'TGA', while seven PCGs terminated with incomplete stop codons (TA or T). Phylogenetic analysis showed that R. nigrocyanea grouped with Cassidinae species, sister to Clytrinae?+?Cryptocephalinae.

A revision and phylogenetic analysis of Stoiba Spaeth 1909 (Coleoptera, Chrysomelidae).

Project description:Stoiba Spaeth, 1909 is revised with a phylogenetic analysis of 38 adult morphological characters for nine Stoiba species and 11 outgroup species (Mesomphaliini, Ischyrosonychini, and Hemisphaerotini). Four Cuban species of Stoiba were not sampled. Parsimony analysis located the four most parsimonious trees. The strict consensus (CI=0.59, RI=0.78, Steps=83) resolved the monophyly of Stoiba. The monophyly of Stoiba is supported by pale yellow antennae, antennomere VII broader than its length, and rounded basal line of pronotum. An illustrated key to ten species of Stoiba is provided along with a distribution map of 11 species. Stoiba rufa Blake is synonymized with Stoiba swartzii (Thunberg) by a morphological comparison which includes female genitalia.
