| Research Abstract |
This research aimed to elucidate the molecular mechanism and physiological significance of the intracellular movement of mesophyll chloroplasts redistributing aggregatively toward the bundle sheath cells of C4 plants in response to environmental stresses. We found that the aggregative movement of mesophyll chloroplasts is induced by abscisic acid, a plant stress hormone, and blue light. A survey of the chloroplast movement in many plant species revealed that the aggregative movement of mesophyll chloroplasts is a universal physiological response of C4 plants, but not C3 plant. It is thought that the response is one of the environmental stress-resistant mechanisms acquired during the evolution from C3 to C4 plants.
