Project description:This experiment examines gene expression profiles in the brains of adult honey bee workers (Apis mellifera) performing different behavioral tasks in the hive. The different behavioral groups examined were nurse, comb builder, guard, undertaker, and forager. The comb builder, guard, and undertaker behavioral groups perform their respective tasks over a relatively short time scale (typically 1 day), while nursing and foraging are longer duration (lasting > 1 week). The purpose of this study was to examine whether behaviors that persist over different time scales are associated with differences in the extent of gene expression changes in the brain.
Project description:Expression profiling of bees that have been selected for their high tendency to perform VSH behavior (VSH+) versus control bees, who performs normal VSH behavior (VSH-)
Project description:Expression profiling of brains of free-flying forager bees and hive-restricted bees that rushed toward the hive entrance when the screen was removed, apparently to attempt to forage.
Project description:We analyzed the changes in brain gene expression after alarm pheromone exposure. Bees from single-drone inseminated colonies were exposed to alarm pheromone at the hive entrance and collected 1h after exposure for analysis.
Project description:Brain expression profiling of bees perfroming consistently vibration signal (modulatory signal that stimulates the performance of several different activities in the hive).
