| Outline of Final Research Achievements |
Strigolactone (SL) is one of important secondary metabolites which regulate plant growth and development. We have previously demonstrated that enzymatic function of Arabidopsis LBO (LATERAL BRANCHING OXIDOREDUCTASE）acting downstream of SL biosynthetic pathway. In the present project, we generated four knockout lines of dioxygenase encoded by genes closed to the LBO clade and examined their shoot branching phenotypes.

| Academic Significance and Societal Importance of the Research Achievements |
地上部枝分かれ制御は作物の質的良的制限に直結する農業生産上重要な形質に一つであるが、その制御メカニズムはほとんど明らかにされていない。本課題成果は、地上部枝分かれ抑制活性本体の単離構造決定につながるものであり、SL生合成経路の全貌およびその調節メカニズムの解明という学術的意義だけでなく、SL生産制御を介した画期的な農業技術の確立という社会的意義を与えるものである。
