Abstract

Striga uses a hypersensitive receptor The strigolactone hormones govern plant growth and development. A nasty parasitic weed, Striga , senses traces of these hormones to identify its targets. After functionally characterizing several strigolactone receptors from Striga , Toh et al. solved the crystal structure of one that is especially sensitive. The structure shows an unexpectedly large ligand-binding pocket, which may explain how Striga manages to sense picomolar concentrations of the range of strigolactones. Science , this issue p. 203
