Global climate change impacts the yield and quality of rice, thereby restricting the sustainable development of agriculture. When plants cope with environmental stress, the interaction among signal generation, perception, transmission, and defense signal networks jointly enhance their stress resistance. Abscisic acid (ABA), as a key plant hormone, plays an important role in coordinating plant growth and adaptation to environmental stress. This review discusses the regulatory mechanisms of ABA in the growth, development, and stress response of rice; analyses the related signaling pathways, gene...
