Transcriptomic and epigenetic responses to social challenge and their association with future behavior in honey bees (ChIP-Seq)

Project description:We studied behavioral, brain transcriptomic and epigenetic responses of honey bees to social challenge. Bees were exposed to two intruders at different intervals. The initial exposure caused two behavioral effects at the individual level: an increase in the intensity of aggression toward a second intruder at 30 and 60 minutes, and an increased probability of responding aggressively toward a second intruder that persisted for two hours. The shorter-lived response was associated with one pattern of gene expression in the mushroom bodies, highlighted by genes related to cytoskeleton remodeling. The longer-lived response was associated with a different pattern; highlighted by genes related to hormones, stress response and transcription factors. Histone profiling revealed few changes in chromatin accessibility in response to social challenge; most differentially expressed genes were “ready” to be activated. These results demonstrate how biological embedding of a social challenge involves changes in the neurogenomic state to influence future behavior.

Trancriptome analysis of honey bees (Apis mellifera) infected with Nosema ceranae

Project description:The microsporidia Nosema ceranae are intracellular parasites that proliferate in the midgut epithelial cells of honey bees (Apis mellifera). To analyze the pathological effects of those microsporidia, we orally infected honey bee workers 7 days after their emergence. Bees were flash frozen 15 days after the infection. Then, the effects on the gut ventriculi were analyzed and compared to non-infected (control) bees.

The habitat disruption induces immune-suppression and oxidative stress in honey bees

Project description:Background: Honey bee is a major insect used for pollination of a number of commercial crops worldwide. However, the number of managed honey bee colonies has recently declined in several countries, and a number of possible causes are proposed. Although the use of honey bees for pollination can be considered as disruption of the habitat, its effects on honey bees' physiology have never been addressed. In Japan, more than 100 thousands colonies are annually used for pollination, and intriguingly 80% of them are used in greenhouses. Recently, honey bee colonies have often collapsed when they are introduced into greenhouses. Thus, to suppress colony collapses and maintain the number of worker bees in the colonies are essential for successful long-term pollination in greenhouses and recycling honey bee colonies.

Expression differences related to phenobarbital feeding in worker honey bees

Project description:The drug phenobarbital induces cytochrome P450 monooxygenase (P450) gene expression in many animals, but no changes in P450 expression, or expression of any detoxification genes, were observed in worker honey bees fed on phenobarbital-candy relative to bees fed plain candy.

cGMP modulates responses to queen mandibular pheromone in worker honey bees

Project description:Responses to social cues, such as pheromones, can be modified by genotype, physiology, or environmental context. Honey bee queens produce a pheromone (queen mandibular pheromone; QMP) which regulates many aspects of worker bee behavior and physiology. Forager honey bees are less responsive to QMP than young nurse bees engaged in brood care, suggesting that physiological changes associated with behavioral maturation may modulate response to this pheromone. Since cGMP is a major regulator of behavioral maturation in honey bee workers, we examined its role in modulating worker responses to QMP. Treatment with a cGMP analog, 8-Br-cGMP, resulted in significant reductions in both behavioral and physiological responses to QMP in young caged workers. Treatment significantly reduced attraction to QMP (the retinue response) and inhibited the QMP-mediated increase in vitellogenin levels in the fat bodies of worker bees. Genome-wide analysis of brain gene expression patterns demonstrated that cGMP has a larger effect on expression levels than QMP, and that QMP has specific effects in the presence of cGMP, suggesting that some responses to QMP may be dependent on an individual beesM-^R physiological state. Several functional gene categories were significantly differentially expressed, including genes involved in regulating GTPase activity, phototransduction, immunity, and carboxylic acid transmembrane transporter activity. Overall, our data suggest that cGMP-mediated processes play a large role in modulating responses to queen pheromone in honey bees, at the behavioral, physiological and molecular levels.

Nutrigenomics in honey bees: the impact of pollen nutrients on bee health

Project description:We studied the molecular mechanisms underlying the impact of pollen nutrients on honey bee (Apis mellifera) health and how those nutrients improve resistance to parasites. Using digital gene expression, we determined the changes in gene expression induced by pollen intake in worker bees parasitized or not by the mites Varroa destructor, known for suppressing immunity and decreasing lifespan of bees.
