Outline of Final Research Achievements	In contrast to mobile animals, which can seek environments suitable for survival, immobile plants must use their flexible and efficient environmental response systems in order to respond rapidly to a variety of environmental changes. However, it remains unclear how plants control, assess, remember, and transmit information from the environment without brains or nerves. This area of study seeks answers to profound and longstanding biological questions. Our objective is to understand the mechanisms of plastic growth in response to the environment that are unique to plants. To this end, we seek to elucidate the long-distance signal transduction system ? which is completely different from those of animals ? that constitutes the local and autonomous environmental response system. Additionally, elucidation of the environmental memory system, which involves spatiotemporal caching of information via chromatin modifications, will be important for understanding plastic growth.
