Biochem/physiol Actions

Highly potent & selective strigolactone receptor ShHTL7 agonist. Femto-/Pico-molar germination stimulant of the parasitic plant Striga hermonthica/Orobanche minor.
Sphynolactone-7 (SPL-7) is an active site-targeting, highly potent and selective strigolactone receptor ShHTL7 agonist (YLG competitive binding IC50 = 310 nM/ShHTL7, 1.2 μM/ShHTL8, >7.0 μM/ShHTL2-6, ShHTL9-11, AtD14) that acts as a seeds germination stimulant with femtomolar- and picomolar-level potency, respectively, toward the parasitic plants Striga hermonthica ecotypes and Orobanche minor, while exhibiting no Arabidopsis-stimulatory efficacy.

The parasitic plant Striga hermonthica has been causing devastating damage to the crop production in Africa. Because Striga requires host-generated strigolactones to germinate, the identification of selective and potent strigolactone agonists could help control these noxious weeds. We developed a
