磷是植物的三大常量营养素之一。由于其在土壤中的低移动性和高固定，低磷有效性是一个世界性的限制作物生产力的因素。分子生物学为提高植物的磷效率提供了很好的机会。然而，在整合所有关于提高作物/牧场磷效率瓶颈的知识之前，转基因植物不能商业化。本文综述了提高作物/牧草磷效率的生物工程的主要策略，包括常规育种和分子辅助育种，生物技术植物关键基因的识别和应用。它强调了通过将生物工程与磷肥和栽培管理相结合来提高磷效率的理解的最新进展。
Phosphorus (P) is one of the three macronutrients for plants. Because of its low mobility and high fixation in soils, low P availability is a worldwide constraint for crop productivity. Molecular biology provides great opportunities to improve P efficiency in plants. However, transgenic plants cannot be commercialized before integrating all the knowledge on bottlenecks for improving P efficiency of crops/pastures. This review intends to summarize the main strategies of bioengineering to improve P efficiency of crops/pastures, including conventional and molecular assisted breeding, identification and application of key genes for biotech plants. It highlights recent advances in the understanding of improving P efficiency through the integration of bioengineering with P fertilization and cultivation management.
