Hypothesis
The study investigates how the transcriptional activity of the rst gene influences the concentration of kirre mRNA during the final stages of eye development in Drosophila.
Conclusion
The study concludes that the expression of the rst and kirre genes is co-regulated and that kirre can compensate for the loss of rst function during eye development.
Supporting Evidence
- Rst protein redistribution in interommatidial cells correlates with changes in rst mRNA levels.
- High levels of kirre expression can compensate for the loss of rst function during eye development.
- Both rst and kirre are co-regulated at the transcriptional level.
Takeaway
This study shows that two genes, rst and kirre, help Drosophila develop their eyes, and if one doesn't work, the other can step in to help.
Methodology
The researchers used quantitative real-time PCR to analyze the transcriptional dynamics of rst and kirre in the developing retina of Drosophila.
