Abscisic acid (ABA) acts as a major phytohormone in regulating seed dormancy and germination. Endogenous ABA level in the seed and embryo sensitivity to ABA jointly regulate the seed dormancy and germination processes, ensuring that the dormant seed can maintain self-reproductive ability under adverse situations and germinate under optimal conditions. A number of key genes are involved in regulating the ABA metabolism and signaling transduction pathway, and these genes accurately control the processes of embryogenesis, seed maturation, dormancy, and germination via a complicated regulation network. In this paper, we review the latest research in the molecular mechanism of ABA-regulated seed dormancy and germination and pinpoint prospects for future research.
