Abstract
GLYCOGEN SYNTHASE KINASE 3 (GSK3), a negative regulator of brassinosteroid signaling, phosphorylates and stabilizes the seed dormancy protein DOG1L4, which in turn activates ABSCISIC ACID INSENSITIVE 5 (ABI5) to enhance seed dormancy. GSK3 also phosphorylates ABI5. This dual-target mechanism suggests a strategy for controlling seed dormancy and germination in crops.
