| Outline of Final Research Achievements |
The organelle arrangement is different between mesophyll and bundle sheath cells, which are two types of photosynthetic cells of C4 plants, and is closely related to metabolic pathways. In this study, we aimed to elucidate the molecular mechanism and physiological significance of the organelle arrangement, and obtained the following results. (1)The intracellular arrangement and shape of bundle sheath chloroplasts in gramineous plants were three-dimensionally understood. (2)The three-dimensional changes in the intracellular arrangement and morphology of the mesophyll chloroplasts were revealed. (3)The acquisition step of the aggregation movement of mesophyll chloroplasts during the evolution of C4 plants was clarified. (4)The opposite distribution of Rubisco and starch granule was revealed in the bundle sheath chloroplasts of NAD-ME type C4 plants.
