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.
Inhibitor of Arabidopsis GSK-3, SHAGGY-related Kinase, and GSK-3-like Kinase BIN2
Glycogen synthase kinase 3 (GSK3) is a key regulator in signaling pathways in both animals and plants. Three Arabidopsis thaliana GSK3s are shown to be related to brassinosteroid (BR) signaling. In a phenotype-based compound screen we identified bikinin, a small
DNA demethylation is important for the erasure of DNA methylation. The role of DNA demethylation in plant development remains poorly understood. Here, we found extensive DNA demethylation in the CHH context around pericentromeric regions and DNA demethylation in the CG
Casein kinase 1 (CK1) is an evolutionarily conserved protein kinase family among eukaryotes. Studies in non-plants have shown CK1-dependent divergent biological processes, but the collective knowledge regarding the biological roles of plant CK1 lags far behind other members of the

Grain size is a key agronomic trait that determines the yield in plants. Regulation of grain size by brassinosteroids (BRs) in rice has been widely reported. However, the relationship between the BR signaling pathway and grain size still requires further
High temperature adversely affects plant growth and development. The steroid phytohormones brassinosteroids (BRs) are recognized to play important roles in plant heat stress responses and thermotolerance, but the underlying mechanisms remain obscure. Here, we demonstrate that the glycogen synthase kinase
