Hypothesis
Do corals exhibit diurnal patterns of gene expression that are regulated by an endogenous biological clock?
Conclusion
Corals show diurnal patterns of gene expression that are influenced by both light and an internal biological clock.
Supporting Evidence
- Corals exhibit diurnal patterns of gene expression that may participate in the regulation of circadian biological processes.
- Many biological processes in corals vary between day and night, indicating a complex regulatory system.
- Some genes continue to cycle in constant darkness, suggesting they are regulated by an internal clock.
Takeaway
Corals have a daily routine for their genes, which helps them know when to do things like eat and reproduce, even when it's dark.
Methodology
The study used deep RNA sequencing and quantitative PCR to analyze gene expression in coral larvae and adult tissues under different light conditions.
Potential Biases
Potential biases may arise from differences in light intensity and sample handling between larvae and adult tissues.
Limitations
The study was limited to two time points for sequencing, which may not capture all diurnal patterns.
Participant Demographics
The study focused on the coral species Acropora millepora, specifically larvae and adult colonies collected from the Great Barrier Reef.
