| Outline of Final Research Achievements |
Mechanisms of drought-induced extra energy dissipation were newly identified in drought-tolerant photosynthetic organisms. Analysis by picosecond fluorescence lifetime measurement revealed this mechanism in a wide variety of species. Fluorescence lifetime was shown to become shorter due to the quenching of excited state that is faster than the photoreaction rate. Similar mechanisms were identified in 5 species of cyanobacteria, 10 species of mosses, 55 species of lichens (symbionts of fungi and cyanobacteria/algae) and 1 higher plant. Different types of mechanism were identified in organisms living under various environments.
