Project description:Seasonal photoperiodic changes have strong impact on development in Nasonia vitripennis. Here, Using high-throughput Reduced Representation Bisulfite Sequencing (RRBS) and single-molecule-based sequencing, we generated DNA methylation maps of female wasps maintained in long vs short day. We have identified differential methylated loci that encode the photoperiodic change. analysis of DNA methylation in female wasps maintained in long vs short day, using RRBS followed by Illumina sequencing

Project description:Honeybees are very important eusocial insects and are involved in the pollination of many plants. Queen bees and worker bees develop from the same fertilized eggs, and are thus genetically identical despite their substantial behavioural and physiological differences. The mechanism governing developmental differences between worker and queen bees has always attracted much interest. While there are several reports on mRNA expression related to caste differentiation, no systematic investigation of small RNAs has thus far been carried out. Results: Using deep sequencing we systematically profiled small RNA expression in 4th-6th day worker larvae and queen larvae (the critical stages at which the fates of workers and queens are determined), and found that 38 miRNAs were differentially expressed between worker and queen larvae. In addition, 639 mature miRNA candidates were identified in our work for the first time, of which, 526 were expressed only in workers (318) or queens (208). Conclusion: We present the first profile of honeybee small RNAs and explore the mechanism of caste differentiation between worker and queen bees. Caste-specific expression patterns and large discrepancies in small RNA profiles between worker and queen bees indicate that small RNAs may be related to the differential development of worker and queen bee larvae. Results presented here will make a valuable contribution to understanding the caste switch between worker and queen bees.

Project description:Parasitoid wasps of the species Diachasmimorpha longicaudata are associated with a heritable poxvirus, known as DlEPV, that is stored in the venom gland of adult female wasps and transferred to tephritid fly hosts of the wasps during oviposition. We conducted a RNA-seq differential expression analysis to gain insight on how DlEPV can replicate in both wasps and their fly hosts but only cause pathogenic effects during replication in flies. Our analysis revealed that 91.2% (176 of 193) of DlEPV genes showed significant differential expression during peak virus replication in wasp venom glands compared to parasitized flies. Over 80% of DlEPV replication genes were significantly upregulated in wasps, while 79% of DlEPV putative virulence genes were significantly upregulated in fly hosts. These data therefore support a dichotomy of viral function, where virus replication is promoted in wasp tissue and virulence in host tissue. Such a division of viral activity could represent an important adaptation to maintain a stable symbiosis between this virus and its associated parasitoid.

Project description:Upon pathogenic infection, drosophila larval host mounts an immune response. Parasitic wasps inject venom that contain virulence factors during oviposition, which can elicit host immune response, and in some cases, suppress host immune responses altogether. Several microarray experiments have been performed on different classes of parasitic wasps. We wanted to compare how Ganaspis xanthopoda-infected hosts respond compared to other classes of parasitic wasps. Third instar y w larvae from a 2-day egglay were infected with G. xanthopoda for three and six hours, respectively, by introducing waps in petri-dish containing larvae. Controls were handled side-by-side without introducing wasps. Host larvae were immediately dissected, infection confirmed by presence of wasp egg, and frozen in liquid nitrogen and ground in Trizol. RNA was isolated and checked by agarose gel-electrophoresis. Samples were then sent to the Microarray Core Facility at Weill Cornell Medical College.

Project description:Experimental infection of (2 days old) adult honey bee workers (30 bees per replicates, 3 replicates per treatments, from 3 different colonies (one colony per cage for each treatment)) with 10^9 genome equivalent of Black Queen Cell Virus (BQCV) in 10µl of sugar solution and/or 10^5 fresh Nosema ceranae spores (control bees were given a similar bee extract in PBS, without pathogen). Bees were kept in cages of 30 bees in incubator (30°C/50%RH). At day 13 p.i., bees were flash frozen, and stored at -80°C. Brain mRNA profiles of 15 old bees were generated by deep sequencing, in triplicates except for bees infected by both Nosema ceranae and Black Queen Cell Virus (duplicates)

Project description:Experiment was designed (i) to analyse the strain composition of Deformed wing virus (DWV) populations in covertly and overtly infected honeybees (Apis mellifera) from Varroa-free and Varroa-infested colonies, and (ii) to determine abundance of the DWV strains following direct injection of the DWV preparations from covertly and overtly infected bees to the bee pupae haemolymph in the absence of Varroa destructor mites. Experiment included isolation of DWV preparations from the following bees: covertly-infected bees from Varroa-free colony, covertly infected bees exposed orally to the Varroa-selected DWV strains, and the overtly infected Varroa-exposed bees. Honeybee pupae were experimentally injected with those DWV preparations and sampled 4 days post injection following development of overt DWV infection. A series of the DWV cDNA fragment covering complete DWV genomic RNA sequences were amplified by RT-PCR using RNA extracted from virus preparations and the injected pupae. The cDNA preparations were sequenced using next generation(Illumina HighSeq 2000) paired-end sequencing to obtain data on the DWV strain composition.
