| Research Abstract |
Reactive oxygen species (ROS) play key roles in intra- / inter-cellular signal transduction. Recent studies revealed that Ca2+-signal and ROS-signal are interplaying for the precise intracellular signal transduction through generating [Ca2+]c oscillation and playing the other key roles of still unknown. In the present study, we tried to develop a novel method to monitor [ROS]c and [Ca2+]c simultaneously using Ca2+- or ROS-sensitive photoproteins and spectrometry of luminescence to clarify the physiological roles and mechanisms of ROS-signal and their interplay with Ca2+-signal in plants.
