| Outline of Final Research Achievements |
We have been constructed novel technique, in which a plant can acquire useful phenotypes by a chemical compound, pyrrole-imidazole (Py-Im) polyamide, which may bind to any nucleotide sequences. In order to construct this technique, we selected an Arabidopsis transcription factor, NST3, of which suppress cause inhibition of cell wall synthesis, and synthesized a compound, of which can bind to NST3 target sequence in MYB46 promoter. By using yeast-one hybrid system, the interaction between synthesized compound and the MYB46 promoter was verified. So we checked the effectiveness of the compound on the Arabidopsis plant. When plants were planted in the compound-containing medium, we observed the growth retardation. The transcriptome analysis suggested that growth retardation was caused by decreasing of expression levels of many genes including these related with synthesis of cell wall. This study is first possibility of regulation of gene expression in plant by using Py-Im polyamide.
