Hypothesis
The evolution of caste diphenism in honey bees involves adoption of TOR signaling as a mechanism for regulating phenotypic plasticity in response to nutrient status.
Conclusion
The TOR pathway is a key factor in determining the developmental fate of honey bee larvae, influencing whether they become queens or workers.
Supporting Evidence
- Queen-destined larvae showed higher levels of amTOR mRNA compared to worker-destined larvae.
- Rapamycin treatment induced worker characteristics in queen-destined larvae.
- amTOR gene knockdown resulted in all individuals developing worker morphology.
Takeaway
Honey bees can grow up to be either queens or workers based on their diet, and a specific pathway in their bodies helps decide which one they become.
Methodology
The study used pharmacology and RNA interference to examine the role of the TOR pathway in caste determination in honey bees.
Limitations
The study primarily focused on late larval stages and may not account for earlier developmental influences.
Participant Demographics
Honey bee larvae from two different colonies.
