Phenotypic plasticity shapes genome architecture in the honeybee Apis mellifera (ChIP-seq)

Project description:Female honeybees are specified as workers or queens based on diet during early development. Workers are essentially sterile with a reduced number of ovarioles and no spermatheca. In the presence of the queen (queen mandibular pheromone) and her brood, worker ovaries are kept in an inactive quiescent state. If the queen is removed, or lost, worker bees are able to sense this change in their environment and their ovaries undergo complete remodelling producing unfertilised haploid eggs that will produce male (drone bees). In this study we analyse gene expression in queen, worker, and laying worker ovaries using RNA-seq and explore differences in the chromatin landscape (focussing on H3K27me3).

mRNA-Seq of brain tissue from honeybee (Apis mellifera) drones (male) and workers (female)

Project description:Transcriptional profiling of brain tissue of was performed by RNA-SEQ in females and males. The sex specific expressed and spliced genes were examined comparing drone and worker honeybees. Examination of mRNA profiles in heads of male and female honeybees pupae were compared.

Comparison of Apis mellifera workers and queens hind leg development at prepupal stages

Project description:In Apis mellifera, the female eggs can develop into workers or queen depending on the diet offered during early development. The outputs of the developed honeybee females are two morphs with particular morphological traits and related physiology. Among the specialized structures in workers the hind tibia forms the corbicula or the pollen basket, a smooth region surrounded by a row of a long scopal hairs, used for carrying pollen and other materials to the nest. This morphological trait and the respective behaviour are absent in queens. Herein we show details of the initial steps of hind legs morphogenesis in honeybee castes. Using results from the hybridization of whole genome-based oligonucleotide arrays with RNA samples from hind leg imaginal discs of pre-pupa honeybees of both castes we present a list of differentially expressed genes.

Comparison of Apis mellifera workers and queens brain development at fourth instar larvae

Project description:In Apis mellifera, the female eggs can develop into workers or queen depending on the diet offered during early development. The outputs of the developed honeybee females are two morphs with particular morphological traits and related physiology. The differential feeding regime experienced by the queen and the worker larvae of the honeybee Apis mellifera shapes a complex endocrine response cascade that ultimately sets up differences in brain morphologies. Herein we report on aspects of brain morphogenesis during larval development and the brain gene expression signature of fourth instar larvae (L4) of both castes, a developmental stage characterized by the greatest differences in juvenile hormone (JH) titers between castes Using results from the hybridization of whole genome-based oligonucleotide arrays with RNA samples from brain of fourth instar larvae honeybees of both castes we present a list of differentially expressed genes.

Analysis used one dye-swap combination to compare workers and queens brain development at fourth instar larvae when juvenile hormone titers is higher in queens.
