Nitrogen and phosphorus are macro-element required by plants, playing important roles in promoting plantgrowth , improving crop yield and quality. Nitrogen and phosphorus deficiency can slow down plant growth, inhibit photosynthesis, affect changes in osmoregulatory substances.membrane systems, and related enzyme activities. At this time.plants will trigger corresponding physiological and molecular response mechanisms to maintain normal growth. Based onthe above research results, this paper reviews the research results on the impaet of nitrogen and phosphorus deficiency onplant growth and development, and summarizes the molecular response mechanisms of plants under nitrogen and phos.phorus deficiency, and key response genes in response to nitrogen and phosphorus deficiency were selected to facilitate theconstrucetion of transgenic plants with high nitrogen and phosphorus utilization efficiency in the future, providing refer.enee for plant cultivation management, sereening, and creating efficient economic plants that utilize nitrogen and phos.phorus.
