Molecular genetic studies on the mechanisms for stress sensing and response in plants.

As autotrophic sessile organism, plants have developed unique systems to regulate biological phenomena such as development, environmental stress responses, and reproduction process. Without central nervous system and sophisticated circulatory system as animals have, plant also developed unique systems to exchange information between cells or tissues. To understand and manipulate the plant behavior, we have been trying to describe the regulatory system for these molecules, deciphering the information possessed by these plant signaling molecules by molecular genetic approaches using model plants such as Arabidopsis.

Establishment of data driven crop design technology.

It has been known that useful agronomical traits of crops are dependent on both the genetic factors the crop possesses and environmental factors the crop lives. Importantly, these two factors are not independent and affect each other in a complex manner.

We have been trying to identify the genetic factors or environmental factors critical to the useful traits by describing the dynamics in physiological status of filed crop through life course concomitant with the filed environment data. Using such important factors, we will build a model that predicts the the agronomical traits. Such the model will enable us to design the crops with suitable genetic factors to a given filed conditions including the forecasted climate in near future.
