| Outline of Final Research Achievements |
When only a small part of the plant is exposed to heat stress, this information transfer to the whole plant (we call it long-distance signaling). Then, mechanisms to respond to severe heat stress are activated in whole plant. In addition, plants possess an ability to remember past exposure to heat stress to be better prepared for subsequent severe heat stress. Based on the knowledge associated with these ability of plants, we attempted to establish the way to enhance heat tolerance of plants by using Arabidopsis plants. We found that plants are able to acquire tolerance to severe heat stress by exposure of only two leaves to heat stress followed by recovery under the normal condition for 3 hours. In addition, tolerance to severe heat stress was also enhanced by direct heat exposure of whole plant only for 5 min followed by 3-hour recovery.
