Bikinin has been used: as a glycogen synthase kinase-3 (GSK3) inhibitor in Arabidopsis Col-0 seedlings to test its effect on gene expressionas a component of induction medium and as a GSK3 inhibitor to test its effect on mesophyll cells in Arabidopsis leaf discs or cotyledonsas a brassinosteroid agonist to test its effect on the leaf index of R. trichophyllus terrestrial leaves
Biochem/physiol Actions
Bikinin is a strong activator of brassinosteroid (BR) signaling. It is an Arabidopsis GSK-3 Inhibitor, an Arabidopsis SHAGGY-related Kinase Inhibitor, and a GSK-3-like Kinase BIN2 Inhibitor. Bikinin directly inhibits BIN2 (group II GSK3s) by interfering with ATP binding. Bikinin is specific toward a subset of Arabidopsis GSK3 kinases including BIN2 and ASK α, γ, ε, ι, and θ.
