Debranone

Phenoxyfuranone-type SL mimics. Agonistic activity for the D14 and AtD14 receptors of strigolactone. Potent bioactivities, including reduction of the tiller number on rice, and stimulation of seed germination in the root parasite Striga hermonthica. Halogenated debranones were more effective than the others and SL agonist GR24 for inhibiting rice tiller but far less effective in the induction of S. hermonthica germination. Nitrile and methyl derivatives clearly stimulated the germination of S. hermonthica seeds
