 The study found that the European honeybees ECR gene is expressed in the brains of both adult workers and foragers, suggesting that it may play a role in regulating metabolism during foraging behavior. Additionally, the study identified several genes that are differentially expressed in the brains of foragers compared to those of nurses, including genes involved in ectosone signaling and metabolic processes. This suggests that ECR may be involved in regulating metabolic processes in the forager brain during foraging behavior.
