Nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) act as an integral regulator of plant core energy metabolism, growth and development, and stress response, which can directly and indirectly influence many key cellular functions. As the cornerstone of cell metabolism, NAD(P)+ homeostasis is crucial for normal plant growth and development, and stress response. Impaired synthesis of NAD(P)+ or deficiency can trigger metabolic disorders and a series of defective phenotypes, and may even lead to plant death in severe cases. Currently, NAD(P)+ biosynthesis pathway and its key enzymes have been well studied in plants, but its homeostatic regulation in plants and the mechanism of coordinating plant growth and stress response are still unclear. Therefore, isolating NAD(P)+ deficiency-related mutants is crucial for exploring the regulatory mechanisms of NAD(P)+ homeostasis and its balancing in plant growth and stress response. This review summarizes the biosynthetic metabolic pathways of plant NAD(P)+, focuses on the participation of NAD(P)+ in plant growth and stress response processes, and looks into the future on the research prospects of NAD(P)+ in plants.
