摘要

Nitrogen (N) and phosphorus (P) are mineral nutrients essential for plant growth and development, playing a crucial role throughout the plant life cycle. Cotton, a globally significant textile crop, has a particularly high demand for N fertilizer across its developmental stages. This review explores the effects of adequate or deficient N and P levels on cotton growth phases, focusing on their influence on physiological processes and molecular mechanisms. Key topics include the regulation of N- and P-related enzymes, hormones, and genes, as well as the complex interplay of N- and P-related signaling pathways from the aspects of N-P signaling integration to regulate root development, N-P signaling integration to regulate nutrient uptake, and regulation of N-P interactions—a frontier in current research. Strategies for improving N and P use efficiency are also discussed, including developing high-efficiency cotton cultivars and identifying functional genes to enhance productivity. Generally speaking, we take model plants as a reference in the hope of coming up with new strategies for the efficient utilization of N and P in cotton.
