Hypothesis
Do the adhesion proteins Capricious and Tartan play redundant roles in the development of the Drosophila eye?
Conclusion
Capricious and Tartan are essential for proper spacing and structure of ommatidia in the Drosophila eye.
Supporting Evidence
- Capricious and Tartan have dynamic expression patterns in the eye imaginal disc.
- Single mutants of Capricious or Tartan show no defects in eye development.
- Double mutants exhibit reduced apical constriction and mispositioning of ommatidia.
Takeaway
Two proteins help cells in the Drosophila eye stick together and stay in the right place as they grow.
Methodology
The study involved creating null mutations of the proteins and analyzing their effects on eye development in Drosophila.
Limitations
The study primarily focused on the roles of Capricious and Tartan without exploring other potential adhesion proteins.
