Assessment of genetic variation in Apis mellifera jemenitica (Hymenoptera: Apidae) using Cytochrome Oxidase I gene sequences

ABSTRACT: The Arabian Honeybee Apis mellifera jemenitica is endemic to the Arabian Peninsula. It is highly adapted to temperature extremes and drought dominating the region. In this study, the mitochondrial Cytochrome Oxidase I (COI) was analyzed in 133 specimens of A. m. jemenitica from eight localities along the Red Sea cost of Saudi Arabia. Results revealed 33 synonymous, and 6 non-synonymous mutations within the COI sequences, resulting in change of 4 amino acids. Phylogenetic analysis based on either type of mutations revealed two main haplogroups accounting for 94% of the samples. In total Eighteen new haplotypes were identified and uploaded in the genebank, Fourteen of them are restricted to one/both haplogroups. All haplotypes identified in this study clustered with reference COI sequences of the sub-lineag Z (African Lineage). However one Haplotype (MW428270) represents high COI variability compared to other haplotypes and may resemble different evolutionary sub-lineage. Tajima's Neutrality Test (Ps = 0.025; D = -1.5) indicated population size expansion that took place after selective sweep and/or purifying selection.

Assessment of Genetic Variation in Apis nigrocincta (Hymenoptera: Apidae) in Sulawesi Revealed by Partial Mitochondrial Cytochrome Oxidase I Gene Sequences.

Project description:Asian cavity-nesting honey bee Apis nigrocincta, a native bee species from Sulawesi and the Philippines, plays a vital role in pollinating flowering plants in local ecosystem and agriculture. In this study, we assessed the intraspecific genetic variation of A. nigrocincta using the sequence of cytochrome c oxidase subunit I (COI). Molecular phylogenetic analysis showed that there were three main clades in A. nigrocincta specimens from Sulawesi based on their respective locations (North, Central, and South Sulawesi). Genetic distance analysis using the Kimura 2-parameter (K2P) model showed that the intraspecific genetic distance in Sulawesi specimens ranged from 0.000 to 0.055. There are 26 nucleotide polymorphic sites within Sulawesi A. nigrocincta. The variation was dominated by transition T ↔ C. The molecular identification result was supported by morphological identification. The results of the two methods agree that the specimen under study was A. nigrocincta. The result of genetic distance calculation indicated that although the tested specimens were derived from remote locations, the genetic variation was still within the range of intraspecific variation.

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.

Crystal structure of peptidoglycan recognition protein SA in Apis mellifera (Hymenoptera: Apidae).

Project description:Peptidoglycan recognition protein SA (PGRP-SA) is a key pattern recognition receptor in the insect innate immune system. PGRP-SA can bind to bacterial PGN and activate the Toll pathway, which triggers the expression and release of antimicrobial peptides to prevent bacterial infection. Here, we report the first structure of Apis mellifera PGRP-SA from Hymenoptera at 1.86 Å resolution. The overall architecture of Am-PGRP-SA was similar to the Drosophila PGRP-SA; however, the residues involved in PGN binding groove were not conserved, and the binding pocket was narrower. This structure gives insight into PGN binding characteristics in honeybees.

Proteomic analysis in the Dufour's gland of Africanized Apis mellifera workers (Hymenoptera: Apidae).

Project description:The colony of eusocial bee Apis mellifera has a reproductive queen and sterile workers performing tasks such as brood care and foraging. Chemical communication plays a crucial role in the maintenance of sociability in bees with many compounds released by the exocrine glands. The Dufour's gland is a non-paired gland associated with the sting apparatus with important functions in the communication between members of the colony, releasing volatile chemicals that influence workers roles and tasks. However, the protein content in this gland is not well studied. This study identified differentially expressed proteins in the Dufour's glands of nurse and forager workers of A. mellifera through 2D-gel electrophoresis and mass spectrometry. A total of 131 spots showed different expression between nurse and forager bees, and 28 proteins were identified. The identified proteins were categorized into different functions groups including protein, carbohydrate, energy and lipid metabolisms, cytoskeleton-associated proteins, detoxification, homeostasis, cell communication, constitutive and allergen. This study provides new insights of the protein content in the Dufour's gland contributing to a more complete understanding of the biological functions of this gland in honeybees.

The complete mitochondrial genome of Apis mellifera meda (Insecta: Hymenoptera: Apidae).

Project description:The complete mitochondrial genome of the western honey bee subspecies Apis mellifera meda was sequenced. This mitochondrial genome is 16,248?bp in length, with 37 classical eukaryotic mitochondrial genes and an A?+?T-rich region. Gene direction and arrangement are similar to those of other Apis mitogenomes. All genes initiate with ATT (six genes), ATG (four genes), ATA (two genes), and ATC (one gene) start codons and terminate with a TAA stop codon. Four genes are encoded on the heavy and nine on the light strands, respectively. All of the 22 tRNA genes, ranging from 66 to 78?bp, have a typical cloverleaf structure. The complete mitogenome of A.m. meda provides information on the biogeography and evolution of A. mellifera subspecies.

Long-Distance Transportation Causes Temperature Stress in the Honey Bee, Apis mellifera (Hymenoptera: Apidae).

Project description:Pollination services provided by the honey bee, Apis mellifera (Hymenoptera: Apidae, Linnaeus, 1758) have broad economic impacts and are necessary for production of a diversity of important crops. Hives may be transported multiple times per year to provide pollination. To test how temperature may contribute to transportation stress, temperature sensors were placed in hives in different locations and orientations on the trailer during shipping. Colony size prior to shipping significantly contributed to loss of population immediately after shipping which contributed to colony failure with smaller colonies more likely to fail and fail faster. Colony size also affects thermoregulation and temperature stress. Internal hive temperature varies significantly based on location and orientation. While colonies near the front and rear of the trailer and those oriented toward the center aisle had significantly different average internal temperatures, colony size best predicts loss of thermoregulation. Additionally, we profiled gene expression at departure, on arrival, and after a recovery period to identify transcriptional responses to transportation. Functional and enrichment analysis identified increased methylation and decreased ribosomal and protein-folding activity. Pheromone and odorant-binding transcripts were up-regulated after transportation. After recovery, transcripts associated with defense response, immune activity, and heat shock decreased, while production of antibiotic peptides increased. We conclude that hives experience considerable temperature stress possibly caused by turbulent airflow in exposed locations. Transportation stress should be considered an important component of annual colony losses which can be mitigated with improved management strategies.

Selectivity of the botanical compounds to the pollinators Apis mellifera and Trigona hyalinata (Hymenoptera: Apidae).

Project description:The toxicity of essential oils that can be used in insect pest management to pollinators needs further studies. Apis mellifera Linnaeus and Trigona hyalinata (Lepeletier) (Hymenoptera: Apidae) foragers were exposed by three pathways to ginger, mint, oregano and thyme essential oils to provide their LC50, LD50 and LC90, LD90. Oregano and thyme were more toxic through contact and topically for A. mellifera while the toxicity of mint and ginger was lower. Trigona hyalinata was more tolerant to the essential oils than A. mellifera. In the walking test, the area was treated (totally or partially) with sub-doses (LC50) obtained via contact. The area fully treated with oregano reduced the distance traveled and the movement speed increased the number of stops by A. mellifera. Similar results were observed for T. hyalinata with oregano and thyme oils. Apis mellifera showed irritability remaining shorter time in the area partially treated with ginger, mint and thyme essential oils while T. hyalinata had similar behavior with ginger and thyme. Essential oils did not repel A. mellifera or T. hyalinata, but those of ginger, mint and thyme reduced the time spent by A. mellifera in areas treated with sublethal doses. Oregano and thyme essential oils reduced the survival, mainly, of A. mellifera, while ginger and mint were selective for both pollinators.
