| Research Abstract |
In this study, we showed that the petal specific InMYB1 promoter recognizes nature of petal cell, but not position of floral organs and that element of this recognition exists 300-200 b upstream of InMYB1. We studied possibilities of molecular breeding to create new flower characters using InMYB1 promoter and transcription factors. Although our trial to make green petal using transcription factor which induce chloroplast formation was not successful, petal morphology of Arabidopsis was successfully changed by controlling transcription factor which controls morphology of epidermal cell.
