Hypothesis
Sema1a signaling will function in the development of the mosquito embryonic nervous system.
Conclusion
Sema1a is required for the development of the insect ventral nerve cord, with some differences in function observed between mosquitoes and fruit flies.
Supporting Evidence
- Sema1a and plexA are expressed in the embryonic ventral nerve cords of Aedes aegypti and Anopheles gambiae.
- Knockdown of sema1a resulted in thinning, breakage, and fusion of the longitudinal connectives in the nerve cord.
- Similar phenotypes were observed in Drosophila melanogaster sema1a loss-of-function mutants.
Takeaway
Sema1a helps mosquitoes develop their nerve cords, and when it's not working right, the nerve cords can be all messed up.
Methodology
The study used siRNA-mediated knockdown to investigate the function of sema1a in Aedes aegypti embryos.
Limitations
The study did not assess motor neuron phenotypes due to the lack of available markers in Aedes aegypti.
