AI Summary (NQ-processed)
A joint research team from Shimane University, Chubu University, RIKEN, The University of Tokyo, Okayama University, and Nagoya University has discovered the AHK3 gene, which regulates the long-distance transport of the plant hormone cytokinin from roots to leaves. By using grafting techniques to reduce AHK3 function specifically in roots, they significantly increased cytokinin levels in root and xylem sap, enhancing leaf growth. This breakthrough opens new possibilities for crop yield improvement.

Frequently Asked Questions
- Q: What is cytokinin in plants?
- A: Cytokinin is a plant hormone that promotes cell division and growth, especially in leaves and shoots.
- Q: Where does the AHK3 gene function?
- A: Mainly in roots, regulating cytokinin perception and transport to influence leaf growth.
- Q: Can this technology be used in agriculture immediately?
- A: Currently demonstrated in model plants, but future application to crops like rice is expected.
- Q: What's the advantage of grafting technique?
- A: It allows genetic changes to be limited to specific organs (e.g., roots), enabling precise analysis.
- Q: What are the next research steps?
- A: Application tests on crops like rice or tomato, and evaluation under environmental stress.
