Strigolactones are a group of terpenoid lactones that act as a host-derived signal in the rhizosphere communication of plants with arbuscular mycorrhiza and root weeds. They also occur as endogenous plant hormones regulating shoot branching in plants. All natural strigolactones contain a tricyclic ring system connected to a butenolide via an enol ether bridge. Most of the germination stimulants identified so far are strigolactones.
