Outline of Final Research Achievements

To understand control mechanisms for the development of Chrysanthemum flowers which are consist of ligulate flowers and tubular flowers, comprehensive genetic analyses were performed in Chrysanthemum morifolium. Microarray analyses were performed using floral organs of ten Chrysanthemum cultivars whose floral morphologies are different from each other. In addition, to obtain the information of function of key transcription factors for the development of ligulate flowers and tubular flowers, microarray analyses were performed using ligulate flowers, tubular flowers, and leave of a Chrysanthemum cultivar. In model plants, transcription factors play important roles in the development of floral organs, therefore, transcript factors were intensively studied in this work.
