| Outline of Final Research Achievements |
The carotenoid-derived strigolactones (SLs) are a class of plant hormones that regulate various developmental processes such as shoot branching and senescence. They also have multiple roles as allelochemicals against arbuscular mycorrhizal fungi and root parasitic plants in the rhizosphere. Natural SLs are structurally divided into canonical SLs and non-canonical SLs with tetracyclic and non-tetracyclic structures, respectively.
It has been reported that canonical SLs, such as 4-deoxyorobanchol and orobanchol, are biosynthesized in rice. In this study, we identified a cytochrome P450 monooxygenase that plays an important role in the production of non-canonical SLs in rice.
