In plants, the phytohormone abscisic acid (ABA) plays a vital role in repressing seed germination and subsequent early seedling establishment, and ABA-INSENSITIVE 3 (ABI3) and ABI5 are two essential regulators of these developmental processes. Although remarkable progress has been achieved in recent years, the precise mechanism of how ABA signaling is attenuated still need to be further explored.
