Background:
Sphynolactone-7 (SPL7) is an agonist ofStrigahyposensitive to light receptor 7 (ShHTL7), which is found in the parasitic plantS. hermonthica.1It 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 inducesS. hermonthicaseed 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 ofS. hermonthicaseeds and decreases the number of plants emerging from the soil, as well as reducesS. hermonthica-induced senescence in maize plants when pre-applied to the soil of co-cultivated maize plants andS. hermonthicaseeds at a concentration of 10 nM.
