Characterization of the mitochondrial genome of Phyllomimus sp. (Orthoptera: Pseudophyllidae).

ABSTRACT: The nearly complete mitochondrial genome (mitogenome) without tRNA-Met and with a partial A?+?T-rich region of phyllomimus sp. has been sequenced with the length of 15,543?bp. We found 140?bp-long intergenic spacers (IGSs) which located between tRNA-Gln and ND2, while this region should be tRNA-Met in most orthopteran mitogenomes. The content of As, Ts, Cs Gs and AT in the mitogenome is 37.3%, 32.5%, 20.6%, 9.5% and 69.8%, respectively. All protein-coding genes start with typical ATN codon except for ND1, which initiates with TTG codon instead, and end with either complete TAA/TAG codons or incomplete T(aa) codons. Phylogenetic analysis indicated that genetic distances of phyllomimus sp. and Orophyllus montanus was closer than other species.

The nearly complete mitochondrial genome (mitogenome) without tRNA-Met and with a partial A + T-rich region of phyllomimus sp. has been sequenced with the length of 15,543 bp. We found 140 bp-long intergenic spacers (IGSs) which located between tRNA-Gln and ND2, while this region should be tRNA-Met in most orthopteran mitogenomes.

Characterization of the mitochondrial genome of Alloxiphidiopsis emarginata (Orthoptera, Tettigoniidae, Meconematinae).

Project description:The length of Alloxiphidiopsis emarginata complete mitogenome was 16,207 bp and contained the typical gene arrangement, base composition, codon usage found in other related species. The overall base composition exhibited obvious anti-G (10.6%) and AT bias (71.6%). The initiation codons of all PCGs were typical ATN (ATA/ATG/ATT), and the termination codons were TAA, TAG, or incomplete stop codon T. All tRNAs could be folded into typical cloverleaf secondary structures, except tRNASer (AGN). Phylogenetic analyses showed that A. emarginata was closer with Xizicus howardi.

Complete Mitochondrial Genome Sequence of Acrida cinerea (Acrididae: Orthoptera) and Comparative Analysis of Mitochondrial Genomes in Orthoptera.

Project description:The complete 15,599-bp mitogenome of Acrida cinerea was determined and compared with that of the other 20 orthopterans. It displays characteristic gene content, genome organization, nucleotide composition, and codon usage found in other Caelifera mitogenomes. Comparison of 21 orthopteran sequences revealed that the tRNAs encoded by the H-strand appear more conserved than those by the L-stand. All tRNAs form the typical clover-leaf structure except trnS (agn), and most of the size variation among tRNAs stemmed from the length variation in the arm and loop of TΨC and the loop of DHU. The derived secondary structure models of the rrnS and rrnL from 21 orthoptera species closely resemble those from other insects on CRW except a considerably enlarged loop of helix 1399 of rrnS in Caelifera, which is a potentially autapomorphy of Caelifera. In the A+T-rich region, tandem repeats are not only conserved in the closely related mitogenome but also share some conserved motifs in the same subfamily. A stem-loop structure, 16 bp or longer, is likely to be involved in replication initiation in Caelifera and Grylloidea. A long T-stretch (>17 bp) with conserved stem-loop structure next to rrnS on the H-strand, bounded by a purine at either end, exists in the three species from Tettigoniidae.

Mitochondrial genome characterization of the family Trigonidiidae (Orthoptera) reveals novel structural features and nad1 transcript ends.

Project description:The Trigonidiidae, a family of crickets, comprises 981 valid species with only one mitochondrial genome (mitogenome) sequenced to date. To explore mitogenome features of Trigonidiidae, six mitogenomes from its two subfamilies (Nemobiinae and Trigonidiinae) were determined. Two types of gene rearrangements involving a trnN-trnS1-trnE inversion and a trnV shuffling were shared by Trigonidiidae. A long intergenic spacer was observed between trnQ and trnM in Trigonidiinae (210-369 bp) and Nemobiinae (80-216 bp), which was capable of forming extensive stem-loop secondary structures in Trigonidiinae but not in Nemobiinae. The anticodon of trnS1 was TCT in Trigonidiinae, rather than GCT in Nemobiinae and other related subfamilies. There was no overlap between nad4 and nad4l in Dianemobius, as opposed to a conserved 7-bp overlap commonly found in insects. Furthermore, combined comparative analysis and transcript verification revealed that nad1 transcripts ended with a U, corresponding to the T immediately preceding a conserved motif GAGAC in the superfamily Grylloidea, plus poly-A tails. The resultant UAA served as a stop codon for species lacking full stop codons upstream of the motif. Our findings gain novel understanding of mitogenome structural diversity and provide insight into accurate mitogenome annotation.

Characterization of the complete mitochondrial genome of the Yunnan endemic grasshopper Longchuanacris curvifurculus (Insecta: Orthoptera: Catantopidae).

Project description:Longchuanacris curvifurculus (L. curvifurculus) was once a dominating grasshopper in the Yunnan province (People's Republic of China) that occupy important ecological niche. However, its population has severely declined because of the deterioration of ecological environment. Identifying the species and source of L. curvifurculus is important for biodiversity conservation and ecological/environmental preservation. In the study, the complete mitochondrial genome of L. curvifurculus was assembled from high-coverage (36.8×) Illumina MiSeq sequencing data. The circular genome is 15,450?bp in length, harboring 37 typical mitochondrial genes and one control region. The nucleotide composition is asymmetric (43.0% A, 14.3% C, 10.5% G, and 32.2% T), with an overall A?+?T content of 75.2%. All the protein-coding genes (PCGs) are initiated with typical ATN start codons and terminated by the typical TAA codons or the incomplete T(aa) codon. The control region has a remarkably high A?+?T content (84.9%) and is located between genes rrnS and trnV.

Characterization of the complete mitochondrial genome of Ergatettix serrifemora (Orthoptera: Tetrigidae) from China and its phylogenetic analysis.

Project description:The mitochondrial genome (mitogenome) of the Ergatettix serrifemora (Orthoptera: Tetrigidae: Tetriginae) was sequenced and annotated. The assembled mitochondrial genome was 14,947 bp, containing 45.8% of A, 15.7% of C, 9.6% of G and 28.9% of T, respectively, which is the classical structure for insect mitogenome. The region that we failed to sequence was between rrnS and trnI, and generally contained a putative AT-rich region. Twelve PCGs started with typical ATN codon and eleven ended with complete stop codons (three with TAG, eight with TAA). The phylogenetic trees in the current study confirmed that E. serrifemora was clustered with other Tetriginae species, and this study would improve our understanding for the mitogenomes of Tetrigoidea.

The complete mitochondrial genome of Calliptamus abbreviatus Ikovnnikov (Orthoptera: acridoidea).

Project description:Calliptamus abbreviatus Ikovnnikov (Orthoptera: Acridoidea) is one of the important pests in the grasslands in northern China. The complete mitochondrial genome of this insect was sequenced. This genome is 16,615?bp long, with an AT content of 73.3%, containing 37 typical animal mitochondrial genes and an AT-rich region. All 13 PCGs share the start codon ATN, and the usual termination codons (TAA) are found from 13 protein-coding genes. All of the 22 typical animal tRNA genes were found in C. abbreviatus mt-genome, and most of the tRNAs could be folded into the classic cloverleaf secondary structure except for tRNA-Ser (AGN), which lacks the dihydrouracil (DHU) stem. The sizes of the large and small ribosomal RNA genes are 1555 and 799?bp long, respectively. The AT content of the AT-rich region is 87.0%. Phylogenetic analysis supports that the coleopteran insects from the same family cluster in the same group.

The complete mitochondrial genome of Eclipophleps carinata (Orthoptera: Acridoidea: Gomphoceridae).

Project description:The complete Eclipophleps carinata mitogenome was sequenced through Illumina HiSeq 2500 platform and the resulting data were analyzed in this paper. The mitochondrial genome of E. carinata is a typical circular DNA molecule of 15,781 bp with 37 genes and 74.5% A + T content, which encoded 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and the control region. The E. carinata mitochondrial genome and 27 mitochondrial genomes (downloaded from NCBI) were employed to construct phylogenetic tree, in which Ruspolia dubia and Teleogryllus occipitails were the outgroups. Phylogenetic reconstruction validated the taxonomic status of E. carinata, which was placed in the monophyletic Gomphocerinae in Acrididae.
