Phosphorus (P) is an essential macronutrient for plant growth, but low P availability in soils is also a primary constraint to crop production. To meet the increasing demands for food, P fertilizer applications have been increased, causing the accumulation of surplus P in soils, which has led to the frequency and magnitude of associated risk effects on agroecosystems. Finding solutions for efficient and sustainable crop P utilization is, therefore, an urgent priority. This review summarizes recent progress in bioengineering approaches to improving crop P efficiency and highlights that modifying root architecture in P-deficient soils and reducing P accumulation in grains in soils with P surplus could offer a way forward for improving P use efficiency.
磷（P）是植物生长必需的大量营养素，但土壤中有效磷含量低也是作物生产的主要限制因素。为了满足对粮食日益增长的需求，磷肥施用量不断增加，导致土壤中磷的过量积累，这增加了对农业生态系统产生相关风险影响的频率和程度。因此，找到提高作物磷利用效率的高效且可持续的解决方案是当务之急。本综述总结了生物工程方法在提高作物磷效率方面的最新进展，并强调在缺磷土壤中改变根系结构以及在磷过剩土壤中减少谷物中的磷积累，可能为提高磷利用效率提供一条前进的道路。
