Project description:Social caste determination in the honey bee is assumed to be determined by the dietary status of the young larvae and translated into physiological and epigenetic changes through nutrient-sensing pathways. We have employed Illumina/Solexa sequencing to examine the small RNA content in the bee larval food source, and show that worker jelly is enriched in miRNA complexity and abundance relative to royal jelly. The miRNA levels in worker jelly were 7-215 fold higher than in royal jelly, and both jellies showed dynamic changes in miRNA content during the 4th to 6th day of larval development. Adding specific miRNAs to royal jelly elicited significant changes in queen larval mRNA expression and in morphological characters of the emerging adult queen bee. We propose that miRNAs in the nurse bee secretions constitute an additional element in the regulatory control of caste determination in the honey bee.

We propose that miRNAs in the nurse bee secretions constitute an additional element in the regulatory control of caste determination in the honey bee. We collected worker and royal jelly of the Italian honeybee (ZND No.1, Apis mellifera ligustica) at 73~90 hours (4th-day larvae), 97~114 hours (5th-day larvae), and 121~138 hours (6th-day larvae) after hatching. After total RNA was extractedM-BM- and quantified , relative equal amounts of total RNAs from each of the three sampling days were pooled into respectively worker and royal jelly samples, and the fraction of small RNAs less than 30nt long was retained and sequenced on the Illumina/Solexa high-throughput platform (HTP).

After total RNA was extractedM-BM- and quantified , equal amounts of total RNAs from each of the three sampling days were analyzed on the LC Science miRNA-array to observe the expression variation of miRNAs between worker jelly and royal jelly along with the development time points (4th-day, 5th-day and 6th-day).

Project description:The timing and amplitude of reproductive effort are central life history variables for all organisms. In social insects, reproductive effort is collectively controlled at the colony level but little is known about the mechanisms that determine how much colonies invest in reproduction. As part of their female reproductive investment, honey bee colonies raise multiple new queens by feeding royal jelly to female larvae. Artificial selection for commercial royal jelly production in China has generated over the past 40 years a stock of royal jelly bees that raises an order of magnitude more queens and provisions each queen with >3x more royal jelly than unselected stock. Here we establish in a reciprocal cross-fostering experiment that this dramatic shift in social phenotype is due to changes in the nurse bees that care for the brood. We demonstrate higher electrophysiological responsiveness to brood pheromones in royal jelly bees than in unselected bees. Comparing the antennal proteome of unselected and royal jelly bees, we identify proteins involved in chemosensation and energy metabolism as candidates for the observed differences. We confirm several candidates, most prominently OBP16 and CSP4, with quantitative differences of corresponding mRNA levels and functional binding assays between the brood pheromones and the chemosensory proteins. Furthermore, we complement analyses of brood volatiles and electrophysiological recordings with behavioral attraction assays to confirm the presumed biological function of one newly discovered and two existing larval pheromones. Together, these findings help our understanding of pheromonal communication in honey bees and explain how sensory changes in nurse honey bees as alloparental caregivers have evolved in response to artificial selection, leading to a profound shift in colony-level resource allocation to sexual reproduction.
