A working model for the ABI5–FLZ13 module in seed germination and seedling establishment.

After seed germination under suitable conditions, the level of ABA and the activity of ABI5 decrease, diminishing the suppression of downstream growth-related genes to promote normal germination and seedling establishment. If germinating seeds are exposed to adverse conditions, the increased ABA activates ABI5, and the ABI5–FLZ13 module represses transcription of growth-related genes to arrest seedling establishment.
