Sphynolactone-7 (SPL7) is an agonist of Striga hyposensitive to light receptor 7 (ShHTL7), which is found in the parasitic plant S. hermonthica.1 It selectively binds to ShHTL7 (IC50 = 0.31 µM) over ShHTL2-6, ShHTL9-10, and the strigolactone receptor AtD14 at 10 µM but does inhibit ShHTL8 and ShHTL11 (IC50s = 1.2 and 7.8 µM, respectively). SPL7 induces S. hermonthica seed germination in the absence of a host, which is fatal to this obligate parasite, with a minimum effective concentration of 10 fM. It induces suicidal germination of S. hermonthica seeds and decreases the number of plants emerging from the soil, as well as reduces S. hermonthica-induced senescence in maize plants when pre-applied to the soil of co-cultivated maize plants and S. hermonthica seeds at a concentration of 10 nM.

A femtomolar-range suicide germination stimulant for the parasitic plant Striga hermonthica
Science 2018 Dec 14;362(6420):1301-1305.PMID:30545887DOI:10.1126/science.aau5445
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 selective agonist, Sphynolactone-7, a hybrid molecule originated from chemical screening, that contains two functional modules derived from a synthetic scaffold and a core component of strigolactones. Cooperative action of these modules in the activation of a high-affinity strigolactone receptor ShHTL7 allows Sphynolactone-7 to provoke Striga germination with potency in the femtomolar range. We demonstrate that Sphynolactone-7 is effective for reducing Striga parasitism without impinging on host strigolactone-related processes.
