| Outline of Final Research Achievements |
Nitrogen is one of the macronutrients of plants and improving the nitrogen use efficiency in plants is important for the sustainable agriculture system. It is thought that plant can monitor the cellular nitrogen status, which is required to response drastic changes of the nitrogen metabolic flows rapidly. However, the mechanism has not yet to been elucidated. Here, we found a chloroplastic ACR11 protein as a novel regulator of the plant's nitrogen metabolism. Our study revealed that ACR11 controled the nitrogen assimilation via a direct interaction with Fd-GOGAT. Given two ACT domain in ACR11, ACR11 may act as a nitrogen sensor.
