Janpanese scientists have created a chemical bath to treat plants that reduces the visible chloropasts within the plant. Day to weeks after the treatment, the plant become virtually transparent, allowing scientists to see the inner workings of the plant in a live and real-time manner. Researchers introduce fluorescent proteins that target specifc areas or proteins within the plant while its still alive. The plant is then killed with formaldehye, sectioned, and then frozen. These frozen sections can be further cut into cross section to be examined under the microscope. This method has been tested on rice, tobacco, tomato, cucumber, moss, and other flowering plants.
