- 7. Screening of strigolactone biosynthesis inhibitors
説明
Shoot branching plays an important role in plant morphogenesis. Previous studies have suggested the novel branching hormone derived from carotenoids inhibit bud outgrowth. Recently, it has been reported that strigolactones (SL) act as a novel hormone in shoot branching. Strigolactones are rhizosphere signaling for the root parasitic weeds and symbiotic arbuscular mycorrhizal fungi. In the proposed biosynthesis pathway, carotenoid cleavage dioxygenase 7 (CCD7) and CCD8 are involved in SL biosynthesis and catalyse cartenoid cleavage reaction. 9-cis-Epoxycarotenoid dioxygenase (NCED) is the most characterized CCD in plants, and we previously identified some NCED inhibitors. To design a strigolactone biosynthesis inhibitor, we screened our chemical libraries targeted to NCED and found abamine, previously identified as NCED inhibitor, reduced the level of 5-deoxystrigol in root exudates. However abamineSG, a specific and potent inhibitor of NCED, did not reduced the level of 5-deoxystrigol.
