Project description:We use chromatin immunoprecipitation and high throughput sequencing to produce the first genome-wide maps of chromatin structure in the honeybee at a key larval stage where developmental canalization into queen or worker is irreversible. We find extensive genome-wide differences in H3K4me3, H3K27ac and H3K36me3, many of which correlate with caste-specific transcription. Furthermore, we identify H3K27ac as a key chromatin modification that most robustly defines caste and suggest that these regions may harbour caste-specific cis-acting elements such as enhancers.

Project description:Along with differences in physiological and behavioral characteristics, workers and queens of Apis mellifera also differ in appendage morphology. Some appendage specializations in the hind legs of honeybee workers, which are highly specialized pollinators, deserve special attention. The hind tibia of the worker has an expanded bristle-free region used for carrying pollen and propolis, the corbicula. In queens, this structure is absent. Although these morphological differences have been well characterized, the genetic inputs triggering the development of this alternative morphology have remained unknown. Through microarray analysis, we detected 1,952 genes that are differentially expressed during worker versus queen hind leg development. The gene expression signatures of the two castes have similar patterns of genes controlling development. At the beginning of the last larval instar, Ultrabithorax (Ubx) activators are more strongly expressed than in prepupae and early pupae; at this time Ubx expression is approximately 25 times higher. Within the gene expression signature, we identified a cluster formed by genes in which Ubx, Twist and Zeste binding sites are over-represented. This cluster includes genes for which Drosophila orthologs are known to be bound by Ubx, as in the case of lola. We also tested the extent of Ubx mRNA processing during wing and leg development.

Project description:Female larvae of the honeybee (Apis mellifera) develop into either queens or workers depending on nutrition during larval development. This nutritional stimulus triggers different developmental trajectories, resulting in adults that differ in physiology, behaviour and life-span. To understand how these developmental trajectories are established we have undertaken a comprehensive analysis of differential gene expression throughout larval development. Gene expression of honeybee queen and worker larval samples was analysed at 60 hours with high-throughout sequencing
