(Submitter supplied) Down syndrome cell adhesion molecule (Dscam) gene encodes a cell adhesion molecule required for neuronal wiring. A remarkable feature of invertebrate Dscam is massive alternative splicing generating thousands of different isoforms from three variable clusters of alternative exons. Dscam expression and diversity arising from alternative splicing have been studied during development, but whether they exert functions in differentiated brains has not been determined. more...

(Submitter supplied) Our two main aims were 1) to isolate age-related changes in gene expression in queens of the eusocial bumble bee, Bombus terrestris; and 2) to determine whether experimentally increasing the costs of reproduction (by removing eggs) caused changes in age-related gene expression in these queens. To address these aims we extracted RNA from three key tissues (brain, fat body and ovary) from queens at two time points (10% and 60% mortality phases). more...

(Submitter supplied) The effects of neonicotinoid insecticides (NNIs) on honey bee health is intensely debated, with numerous studies showing negative effects of exposure, while others report no such effects. Understanding the cause of these differences is critical for developing evidence-based policy on the use of NNIs. We carried out experiments to study the genetic and molecular basis of NNI tolerance in honey bees, which may underlie the discrepancies observed in the literature. more...

(Submitter supplied) Overwintering mortality is the greatest threat to the supply of healthy bee colonies available for pollination of spring-blooming crops, but efforts to mitigate colony losses are hindered because underlying mechanisms remain poorly understood. In the present study, we identified that sirtuin signaling pathway is the most significantly affected pathway in collapsing overwintering colonies that carried a high prevalence of pathogens and is a convergent signaling hub that links mitochondrial dysfunction and metabolism alterations. more...

(Submitter supplied) Using the assay for transposase-accessible chromatin by sequencing (ATAC-seq), we produce the first genome- wide maps of chromatin accessibility across all three adult honey bee phenotypes. We identify ~ 3000 regulatory regions in queen, ~ 4500 in worker and ~ 4000 in drone, with the vast majority of these sites located within intronic regions. Integrating ATAC-seq, RNA-seq and ChIP-seq data, we show a positive correlation between chromatin accessibility at introns, flanking H3K27ac modified nucleosomes and abundance of the respective mRNA transcript. more...

(Submitter supplied) It is assumed that climate and land-use changes cause increasing stress to pollinators, which play pivotal roles in almost all terrestrial ecosystems, with consequences on population growth, diversity and ecosystem functions. While these responses to global change drivers are well located, the molecular pathways triggering the response are poorly understood. We analysed the transcriptomic response of Bombus lucorum workers in their systematic responses to temperature and livestock grazing, sampled along an elevational gradient from 650 – 1930 m.a.s.l., and from differently managed grassland sites (livestock grazing vs. more...

(Submitter supplied) The honeybee (Apis mellifera) is a well-known eusocial insect. In honeybee colonies, thousands of sterile workers, including nurse and forager bees, perform various tasks within or outside the hive, respectively. The queen is the only fertile female and is responsible for reproduction. The queen and workers share similar genomes, but occupy different caste statuses. We established single-cell transcriptomic atlases of brains from queens and worker subcastes, and identified five major cell groups: Kenyon, optic lobe, olfactory projection, glial, and hemocyte cells. more...

We conclude that small RNAs are likely to play an integral role in honey bee gametogenesis and reproduction and provide a plausible mechanism for parent-of origin-effects on gene expression and reproductive physiology. present in honey bee reproductive tissues: ovaries, spermatheca, semen, fertilised and unfertilised eggs, and testes.
