Outline of Final Research Achievements

In this project, we performed comprehensive analyses of the WD40 proteins that interact with transcription factors in Arabidopsis, using the trans-repression system and yeast two hybrid system with cDNA library containing only transcription factors, which we had developed. We prepared transgenic Arabidopsis that expressed the chimeric genes of the WD40 protein fused with the SRDX repression domain, and screened the lines with altered phenotype. As a results, we identified that 30 lines that expressed each of WD40-SRDX exhibited altered morphological phenotype. We focused the dwarf lines among them and analysed the transcription factors that interact with the WD40 protein using the yeast two hybrid system.
