| Outline of Final Research Achievements |
When plants are exposed to environmental stress (heat, salt etc.) the translation state changes dramatically. Translation state changes due to heat and salt stress are very similar when compared on the genome wide scale, but there are also mRNAs that differ in translation state change between two stresses such as being maintained by heat but suppressed by salt.
In this study, transient expression experiments and analysis using a transformant in which the 5'UTR of mRNA showing specific behavior was fused to a reporter gene were performed. As a result, the possibility that the CU repeat region in the 5'UTR contribute to the stress state-specific translation state change (heat suppression and salt maintenance) and the change of the translational state of mRNA under heat stress by change of transcription initiation site in response to heat stress were indicated.
