Abstract :
Seed germination of the parasitic plant Orobanche cumana is induced by host-derived strigolactones and dehydrocostus lactone. We show that the KAI2d2 receptor perceives both ligands through distinct modes of interaction. Triazole urea compounds covalently inhibit KAI2d receptors, suppressing germination without affecting sunflower growth. |
