Outline of Final Research Achievements |
We examined the molecular mechanism of light-induced germination in resting spore of a coastal diatom. Photosynthetic activity of resting spore increased just after light-on. Quantity of photosynthetic proteins scarcely changed after light-on, but ATPase increased. Furthermore, proteome analysis indicated that proteins involved in citric cycle, glycometabolism, singling and nutritional metabolism are newly expressed after light-on. These results suggest a scenario that the resting spore used energy to activate nutritional metabolism and so on after light-on, and then photosynthesize to elongate and germinate.
