Prof. Ko Shimamoto (Graduate School of Biological Sciences) received the Prizes for Science and Technology (Research Category) by MEXT on April 11, 2011.
I am very happy to receive the award for the study of flowering regulation and florigen in rice. This research started a few years before I came to Nara and it has been the major project in my laboratory for the last 17 years. Many students, faculty members, and technical staff were involved in this research and I am grateful to all who participated in the project. The main achievements in this area of research are: identification of a conserved and distinct mechanism to generate photoperiodic regulation of flowering in a short day plant, rice and identification of Hd3a protein as a long-sought florigen in rice. These discoveries made a foundation to understand regulation of flowering in plants. The current research in our laboratory is involved in understanding molecular mechanisms for floral induction, role of florigen in growth and differentiation of plants, and development of synthetic florigen which can be used to regulate plant growth and flowering. Our study on these just started and we hope to gain insights into these questions in the future.
