| Research Abstract |
Strigolactones (SLs) are released from plant roots and function as communication signals for symbionts arbuscular mycorrhizal fungi and root parasitic plants in the rhizosphere. In planta, SLs function as a novel class of plant hormones regulating shoot and root architecture. In this study, SLs produced by Marchantia polymorpha, which is evolutionary most apart from angiosperms, and by a fern Selaginella moellendorffii were examined. LC-MS/MS and GC-MS analyses confirmed the presence of SLs in Marchantia and S. moellendorffii extracts, and identified several SLs, and six novel SLs, respectively. These results indicate that SLs existed when plants first colonized land.
