The complete mitochondrial genome of Bombus filchnerae (Hymenoptera: Apidae) and phylogenetic analysis.

ABSTRACT: Here, we report the complete mitochondrial genome (mitogenome) of Bombus filchnerae (Hymenoptera: Apidae). The genome size of B. filchnerae was 18,553 bp with 88.7% A + T content, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an AT-rich control region (D-loop). tRNA rearrangement was observed in this mitochondrial genome when compared to those of other bumblebee species (e.g. Bombus breviceps and Bombus asiaticus). All the 13 PCGs initiated with typical ATN codons. Among them, 11 PCGs terminated with TAA, only nad4 and nad5 with incomplete stop codon TA and T, respectively. All the 22 tRNAs can be folded into typical cloverleaf structure, except for trnS1, whose dihydrouridine (DHU) arm forms a simple loop. The phylogenetic analysis based on the concatenated nucleotide sequences of all 13 PCGs indicated that B. filchnerae showed the closest relationship with Bombus pascuorum, forming a mono clade of the subgenus Thoracobombus, with well-resolved relationships among nine Bombus subgenera.

Complete mitochondrial genome of Bombus breviceps (Hymenoptera: Apidae).

Project description:The complete mitochondrial genome of Bombus breviceps, which belongs to the subgenus of Alpigenobombus in Bombus genus, was sequenced. This circular mitogenome is 16,743 bp (83.5% AT) in length, with two rRNA genes, 22 tRNA genes, and 13 protein-coding genes. All protein-coding genes are initiated with the common invertebrate initiation codon except TTA for ND2, and terminated by the typical stop codon TAA or TAG. tRNA-Ser (TCT) lacks a dihydrouridine (DHU) arm while other tRNA genes form a cloverleaf structure. Phylogenetic analysis shows that genus Bombus has a closer relationship with genus Melipona than any other genera in Apidae family, and B. breviceps clusters closer to B. lapidarius than any other bumblebees with sequenced mitogenome.

Next-generation sequencing of the mitochondrial genome of Bombus longipennis Friese, 1918 (Hymenoptera: Apidae).

Project description:Bombus longipennis is the species of Bumblebees (Hymenoptera: Apidae), which are important pollinators for wild plants and greenhouses crops. The complete mitochondrial genome (mitogenome) of B. longipennis was determined by next-generation sequencing. The mitogenome was 18,458 bp in size with 87.2% A + T content, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an AT-rich control region (D-loop). Gene arrangement was found to be identical to those of other mitogenomes of bumblebees (e.g. Bombus terrestris and Bombus ignitus). All 13 PCGs initiated with typical ATN codons. Among them, 11 PCGs terminated with TAA or TAG; only cox2 and nad4 have incomplete stop codon T. All 22 tRNAs can be folded into typical cloverleaf structure. Phylogenetic analysis based on the concatenated nucleotide sequences of all 13 PCGs indicated that B. longipennis was more closely related to other species of subgenus Bombus, which clustered into a monophyletic group.

The complete mitochondrial genome and phylogenetic analysis of the Arabian Honeybee Apis mellifera jemenitica (Insecta: Hymenoptera: Apidae) from Saudi Arabia.

Project description:Fourteen mitochondrial genomes from workers of the Arabian Honeybee Apis mellifera jemenitica were determined. Genomes range from 16,352 to 16,445 bp. Each consists of 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and one control region. The mitogenome sequences revealed 753 Variable sites in total, distributed within protein-coding loci (199), ribosomal RNAs genes (117), transfere RNAs genes (48), and non-coding AT-rich region's (389). Phylogenetic analysis with Neighbor-Joining method suggested three evolutionary groups for these mitogenomes, closely related to A. m. jemenitica, A. m. lamarckii, A. m. syriaca, and A. m. scutellata.

Project description:The mitogenome of Habropoda rodoszkowskii, the first complete mitogenome sequence of the genus Habropoda (hymenoptera: Apidae), was sequenced. The mitogenome is 18,497 bp (The proportion of A + T in 80.7%) long, with 37 classic eukaryotic mitochondrial genes (including 13 PCGs, 22 tRNAs, and 2 rRNAs) and an AT-rich region (The proportion of A + T in 78.2%). The Bayesian-inference and Maximum-likelihood phylogenetic relationship was constructed using 15 species from Hymenoptera. According to the phylogenetic tree, Habropoda rodoszkowskii converges with genus Nomada bees (Nomada flava and Nomada flavoguttata) to be supported. In addition, Habropoda rodoszkowskii is more closely related to Apidae than to Megahilidae and Colletidae.

The complete mitochondrial genome of the Asiatic cavity-nesting honeybee Apis cerana (Hymenoptera: Apidae).

Project description:In the present study, we determined the complete mitochondrial DNA (mtDNA) sequence of Apis cerana, the Asiatic cavity-nesting honeybee. We present here an analysis of features of its gene content and genome organization in comparison with Apis mellifera to assess the variation within the genus Apis and among main groups of Hymenoptera. The size of the entire mt genome of A. cerana is 15,895 bp, containing 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA (tRNA) genes and one control region. These genes are transcribed from both strands and have a nucleotide composition high in A and T. The contents of A+T of the complete genomes are 83.96% for A. cerana. The AT bias had a significant effect on both the codon usage pattern and amino acid composition of proteins. There are a total of 3672 codons in all 13 protein-coding genes, excluding termination codons. The most frequently used amino acid is Leu (15.52%), followed by Ile (12.85%), Phe (10.10%), Ser (9.15%) and Met (8.96%). Intergenic regions in the mt genome of A. cerana are 705 bp in total. The order and orientation of the gene arrangement pattern is identical to that of A. mellifera, except for the position of the tRNA-Ser(AGN) gene. Phylogenetic analyses using concatenated amino acid sequences of 13 protein-coding genes, with three different computational algorithms (NJ, MP and ML), all revealed two distinct groups with high statistical support, indicating that A. cerana and A. mellifera are two separate species, consistent with results of previous morphological and molecular studies. The complete mtDNA sequence of A. cerana provides additional genetic markers for studying population genetics, systematics and phylogeographics of honeybees.

The complete mitochondrial genome and phylogenetic placement of Apis nigrocincta Smith (Insecta: Hymenoptera: Apidae), an Asian, cavity-nesting honey bee.

Project description:The complete mitochondrial genome of Apis nigrocincta was sequenced. The mitochondrial genome is a circular molecule of 15,855 bp, including 37 classical eukaryotic mitochondrial regions and an A + T-rich region. Gene directions and arrangements are similar to those of other Apis mitogenomes. Most genes initiated with ATT, though ATG and ATA were also used as start codons. Twelve of 13 protein-coding genes terminated with TAA, though ND2 terminated with TAG. Four PCG genes, eight tRNAs and both rRNAs were encoded on the heavy strand while all others were encoded on the light strand (9 PCGs and 14 tRNAs). Overall, the GC content composed 15.6% of the mitogenome. All of the 22 tRNA genes, ranging from 66 to 114 bp, have a typical cloverleaf structure. A phylogenetic tree showed that A. nigrocincta clustered closest to A. cerana. The complete mitogenome of A. nigrocincta provides essential information on the biogeography and evolution of this Asian honey bee species.
