Develpment of stay-green plants through genetic modification of chloroplast functions

 Genetic modification of plant and organelle genomes sometimes results in retained greeness during leaf senescence in plants. These phenomena are referred to as stay-green. Now that our knowledge on photosynthesis and chloroplast functions is significantly increased, it is possible to explore new strategies to develop new types of stay-green plants. In this project, we aim to produce new stay-green plants that have prolonged photosynthetic activity through the modificatin of the photosythetic machinery, the genetic control of the chloroplast quality, and the improvement of the chloroplast function. In addition, we will attempt to understand the fundamental mechanisms pertaining to the biogenesis, the maintenance and the degradation of the chloroplasts.
