Outline of Final Research Achievements

Strigolactones (SLs) function as host recognition signals for root parasitic plants and symbiotic arbuscular mycorrhizal fungi in the rhizosphere and as plant hormones regulating shoot branching in plants. In spite of such important physiological functions in agricultural production, its biosynthetic pathway has not been elucidated. In this study, the functions of SL biosynthetic enzymes MAX1 and LBO were analyzed. As a result, it has been shown that a biosynthetic pathway for two-ring SL derivatives led by MAX1 and LBO exists in plants.
