| Outline of Final Research Achievements |
Plants regulate cell elongation in response to various phytohormones and environmental conditions, and competitive HLH/bHLH systems, controls cell elongation under various signals. The competitive HLH/bHLH systems are composed of typical bHLH transcriptional activators and non-DNA-binding atypical HLH inhibitors; typical bHLH activators directly bind to the DNA and regulate gene expression, and atypical HLH interfere with the DNA binding of the bHLH activators by forming heterodimers. In this study, we tried to isolate novel transcription factors which related to regulation of plant cell elongation. By using the yeast two hybrid method, we isolated 116 candidate factors. The candidate factors included various novel factors in addition to known elongation regulators, PIF4, ACE and PREs.
