Hypothesis
What is the mechanism behind compensation in leaf size control?
Conclusion
The study suggests that the mechanisms controlling leaf size are complex and involve an unknown integration system.
Supporting Evidence
- Leaves are not just the sum of cell size and number; they are controlled by an unknown system.
- Compensation occurs specifically in leaves and related organs with a determinate fate.
- Tetraploid plants are generally larger than diploid plants due to increases in cell size.
Takeaway
Leaves grow bigger when their cells get larger, but it's not just about how many cells there are; there's a special system that controls this.
