| Outline of Final Research Achievements |
Progeny seeds of green foxtail mutagenized by heavy ion beam irradiation were collected. We have established a screening method for mutants that do not cause abscisic acid-responsive aggregative movement of mesophyll chloroplasts with the mutant library. We also revealed that the aggregative arrangement in mesophyll cells occurs even in plastids under the dark conditions or in the early stage of development, while a mechanism for dispersing the chloroplasts is working under the non-stressed light conditions.
