Strigolactones are plant secondary metabolites which function as host recognition signals for arbuscular mycorrhizal (AM) fungi and root parasitic plants, Striga and Orobanche. Plants exudates cocktails of strigolactones and their compositions differ with plant species, their growth stages, and growth conditions. In this study, characterization of strigolactones produced by pea (Pisum sativum L.), a host of Orobanche, was conducted by comparing retention times of germination stimulants on ODS-HPLC with those of synthetic standards and by LC/MS/MS. In the root exudates collected from pea plants grown hydroponically, orobanchol, orobanchyl acetate, and a novel strigolactone were detected as major stimulants. Purification and structural elucidation of the novel strigolactone will be presented.
