Hypothesis
How Zmufo1 regulates BETL differentiation and contributes to grain filling has remained poorly understood.
Conclusion
Zmufo1 encodes a nuclear protein that regulates aspects of the cell's epigenetic status and redox potential, positively influencing BETL differentiation.
Supporting Evidence
- Zmufo1 is strongly expressed in the BETL during differentiation.
- Loss-of-function mutants showed impaired BETL differentiation.
- Overexpression of Zmufo1 led to excessive expression of BETL marker genes.
- Antioxidant treatments alleviated growth defects in mutant lines.
- Increased histone acetyltransferase activity was detected in mutant lines.
- ZmUFO1 localizes in the nucleus and interacts with nuclear proteins.
Takeaway
Zmufo1 is a protein that helps maize plants grow better by keeping their cells healthy and organized, especially in the part that stores food.
Methodology
The study analyzed the effects of Zmufo1 loss-of-function and overexpression on BETL differentiation using specific maize lines.
