| Outline of Final Research Achievements |
Root endodermis is covered by suberin lamellae and Casparian strip to limit movement of water, nutrients, and oxygen between inside and outside of root. In this study, we attempt to identify novel regulators for suberin accumulation and to produce stress tolerant plant by them. We screened transcription factors responsible for suberin or Casparian strip formation by inducing dominant negative phenotype. One of identified transcription factors was demonstrated to be involved in salinity tolerance and seed viability under high humidity and temperature. These results shed light on the development of novel technology conferring biotic and abiotic stress tolerance.
