Project description:Genomic comparison of the sister species V. destructor and V. jacobsoni mite
| PRJDB6279 | ENA
Project description:Experiment was designed to study the effect of Deformed wing virus (DWV) and the mite Varroa destructor on global gene expression using microarray transcriptional profiling in developing worker honeybee (Apis mellifera). Newly hatched bee larvae (day 3 of bee development) were transferred from a Varroa-free colony with low DWV levels to a Varroa-infested colony with high levels of DWV in bees and Varroa mites. All transferred larvae were receiving the DWV strains present in this Varroa-infested colony with the food delivered by the nurse bees until their capping (day 8). About half of these larvae were capped with Varroa mite and were subjected to the mite piercing and feeding on their haemolymph during pupal development until sampling at purple eye stage (day 14). Exposure to the mite piercing and feeding resulted in about 1000-fold increase of the DWV levels in the majority of the mite-exposed pupae compared to the control pupae and the pupae not exposed to Varroa mites.

Project description:The mite Varroa destructor is currently the greatest threat to apiculture as it is causing a global decrease in honey bee colonies. However, it rarely causes serious damage to its native hosts, the eastern honey bees Apis cerana. To better understand the mechanism of resistance of A. cerana against the V. destructor mite, we profiled the metabolic changes that occur in the honey bee brain during V. destructor infestation. Brain samples were collected from infested and control honey bees and then measured using an untargeted liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based global metabolomics method, in which 7918 and 7462 ions in ESI+ and ESI- mode, respectively, were successfully identified. Multivariate statistical analyses were applied, and 64 dysregulated metabolites, including fatty acids, amino acids, carboxylic acid, and phospholipids, amongst others, were identified. Pathway analysis further revealed that linoleic acid metabolism; propanoate metabolism; and glycine, serine, and threonine metabolism were acutely perturbed. The data obtained in this study offer insight into the defense mechanisms of A. cerana against V. destructor mites and provide a better method for understanding the synergistic effects of parasitism on honey bee colonies.

Project description:The parasitic mite Varroa destructor causes both direct and indirect damage to infested honeybees but precise information about the identity of the metabolic pathways that are affected is still missing. In order to gain a deeper knwoledge about the effects of parasitization at various levels, while reducing to the miminum the impact of possible confounding factors, a standardized experiment was carried out under artificial condition.

Project description:Using artificial Parafilm™ dummies, we explored the nutrition of V. destructor females and assessed their survival when fed on hemolymph from bee larvae, pupae or adults. We compared the results to fully synthetic solutions and to filtered larval plasma. The results showed that the parasites could survive for several days or weeks on our different diets. Hemolymph from larva yielded the highest survival rates and filtered cell-free hemolymph was sufficient to maintain the mites for 14 days or more. This cell free solution thus theoretically contains all necessary nutrients for the mite survival. A proteomic analysis on the larval plasma outlined a list of 54 proteins among which several energy metabolism proteins such as vitellogenin, hexamerin or transferrin. These molecules represent key candidate nutrients that could be crucial for V. destructor survival.

Project description:Aims of the project is the identification of soluble chemosensory proteins in the olfactory organs of the honeybee mite Varroa destructor. Different families of soluble proteins acting as carriers for odorants have been identified in hexapods, while very limited information is available for other terrestrial Arthropoda. In mites and ticks olfactory organs are located on the distal part of the forelegs and on the capitulum appendages. These two body tagmata and the second pair of legs as control, have been dissected out of phoretics and reproductives Varroa destructor females and protein extracts have been analysed through shotgun proteomics. Protein identification and relative quantification (Label-free quantification, LFQ) has been performed using MaxQuant (version 1.5.8.3). Among the proteins more abundant in appendages bearing chemosensory organs, considering as a model hexapoda soluble olfactory proteins, we have searched for small secreted proteins whose structure include a hydrophobic binding pocket.

Project description:Background The number of managed honey bee colonies has considerably decreased in many developed countries in recent years and the ectoparasitic mites are considered as major threats to honey bee colonies and health. However, their general biology remains poorly understood. Results We sequenced the genome and transcriptomes of Tropilaelaps mercedesae, the prevalent ectoparasitic mite infesting honey bees in Asia. The de novo assembled genome sequence (353 Mb) represents 53% of the estimated genome size because of the compression of repetitive sequences; nevertheless, we predicted 15,190 protein-coding genes which were well supported by the mite transcriptomes and proteomic dataes. Although amino acid substitutions have been accelerated within the conserved core genes in of two mites, T. mercedesae and Metaseiulus occidentalis, T. mercedesae has undergone the least gene family expansion and contraction between the seven arthropods we tested. The number of sensory system genes has been dramatically reduced; meanwhile, T. mercedesae may have evolved a specialized cuticle and water homeostasis mechanisms, as well as epigenetic control of gene expression for ploidy compensation between males and females., and water homeostasis. T. mercedesae contains all gene sets required to detoxify xenobiotics, enabling it to be miticide resistant. T. mercedesae is closely associated with a symbiotic bacteriuma (Rickettsiella grylli-like) and DWVdeformed wing virus (DWV), the most prevalent honey bee virus. The presence of DWV in both adult male and female mites was also confirmed by the proteomic analysis. Conclusions T. mercedesae has a very specialized life history and habitat as the ectoparasitic mite strictly dependsing on the honey bee inside the a stable colony. Thus, comparison of the genome and transcriptome sequences with those of a tick and free-living mites and tick has revealed the specific features of the genome shaped by interaction with the honey bee and colony environment. T. mercedesae, as well as Varroa destructor, genome and transcriptome sequences not only provide insights into the mite biology, but may also help to develop measures to control the most serious pests of the honey bee.
