摘      要：Dear Editor Strigolactones （SLs） are novel phytohormones that shape plant architecture by inhibiting shoot branching and regulating root growth, besides their established functions in stimulating seed germination of root-parasitic weeds, such as Striga and Phelipanche species, and inducing hyphal branching in arbuscular mycorrhizal （AM） fungi （AI-Babili and Bouwmeester, 2015）. Canonical SLs are divided into strigoland orobanchollike subfamilies with a typical structure consisting of a tricyclic （ABC-ring） and a monocyclic lactone （D-ring）, which are connected by an enol ether bridge （Figure 1A and Supplemental Figure 1）. SLs are synthesized from carotenoids via carlactone, which lacks the B/C-ring （Alder et al., 2012）. In Arabidopsis, carlactone （Figure 1A） is converted by MAX1, a member of the CYP711 family, into carlactonoic acid, after methylation, which, can bind to SL receptor （Abe et al., 2014）. In rice, a MAX1 homolog, the carlactone oxidase, introduces B/C-rings into carlactone,
