| Outline of Final Research Achievements |
Here, we aimed to identify novel factors that make anthocyanins blue and to elucidate the mechanism that yields a pure blue flower color through anthocyanins. This work is useful for breeding ornamental flowers that possess a more beautiful, vibrant blue color. Using the species Nigella damascena and Vinca minor, factors related to the development of blue flowers including the pH, pigment composition, and pigment structures of petals and sepals were investigated and compared between the blue and red flowers of each plant. We are currently proceeding with further verification about the new candidate factors that could influence the blue pigmentation of the anthocyanins identified here. Furthermore, we identified three novel anthocyanins in a series of studies.

| Academic Significance and Societal Importance of the Research Achievements |
青色花色を担う色素はアントシアニンである。アントシアニンがどのような条件で青く発色するようになるのかについて解明することは、花色研究分野で長い間取り組まれてきたテーマであり、新たな知見が蓄積されることになる。園芸花きの中には青色花色を欠く品目が多い。青色花色品種の育種を行う上でも、アントシアニンの青色発現の仕組みは、基礎科学的な情報として有用である。新たなアントシアニン青色化条件の候補因子が見つかることは、青色花色品種育成が潜在的に可能となる植物種の幅を広げる可能性があると考えている。
