Strigolactones are plant hormones that control diverse aspects of plant growth, but are also exuded into soil as recruitment signals for arbuscular mycorrhizal fungi interactions. Highly damaging parasitic weeds in the Orobanchaceae family have coopted strigolactones as germination cues that indicate the presence of a host. Recent studies have established how strigolactones are actively transported within and out of plants. Key components of the strigolactone signaling system have been identified, including strigolactone receptors in angiosperms and parasites, as well as downstream targets that are polyubiquitinated and proteolyzed following strigolactone perception. The basis for protein-protein interactions among these signaling components has also been explored. We propose several strategies to translate current knowledge of strigolactone transport and signaling into parasite control methods. |
