| Research Abstract |
Stringent response is a global regulatory system in bacteria that responds to nutrient conditions. Recently, stringent response-related genes have been identified in plants, although physiological function of the genes are not clarified. In this study, we characterized genetically modified Arabidopsis in which stringent response-related genes are over-expressed. The results indicated that plant stringent response is function in chloroplasts that controls a wide variety of metabolic and gene expression processes.
