| Outline of Final Research Achievements |
The major component of plant tissues is water. Water freezes at sub-zero temperatures. Wintering woody perennials are exposed to recurrent freezing temperatures. How do these plant organs can avoid lethal intracellular freezing? In this study, noninvasive visualization of freezing behaviors in these thick complicated plant organs was successfully achieved using high resolution temperature-variable MRI. The results show that the method is very powerful in investigating the diversity, dynamics and mechanisms of freezing behaviors. We also successfully constructed a temperature-variable probe for MRI system in Japan and successfully visualized freezing behaviors of plant tissues.
