低磷（P）有效性是大豆生长和生产的主要限制。培育能有效利用土壤中自然磷和外源磷的磷高效大豆品种是大豆生产可持续发展的经济途径。本文以大豆磷效率的研究为例，综述了大豆磷效率的可能机制和提高磷效率的遗传策略。它还强调了潜在的障碍，并描绘了未来的前景，在'根育种'。结论为大豆磷效率的机理及磷效率育种策略提供了新的思路。根系生物学是植物生物学研究的一个新的前沿领域。目前，通过“根育种”来提高大豆磷效率已成为大豆生产中的一项重要工作。为了推进这一领域的发展，需要植物育种家和生理学家之间的进一步合作，以及应用和理论研究，以开发更多的大豆品种，通过根系改造提高磷效率，这可能有助于减少磷肥的使用，扩大低磷土壤上的农业，并实现更可持续的农业。
BACKGROUND Low phosphorus (P) availability is a major constraint to soybean growth and production. Developing P-efficient soybean varieties that can efficiently utilize native P and added P in the soils would be a sustainable and economical approach to soybean production. SCOPE This review summarizes the possible mechanisms for P efficiency and genetic strategies to improve P efficiency in soybean with examples from several case studies. It also highlights potential obstacles and depicts future perspectives in 'root breeding'. CONCLUSIONS This review provides new insights into the mechanisms of P efficiency and breeding strategies for this trait in soybean. Root biology is a new frontier of plant biology. Substantial efforts are now focusing on increasing soybean P efficiency through 'root breeding'. To advance this area, additional collaborations between plant breeders and physiologists, as well as applied and theoretical research are needed to develop more soybean varieties with enhanced P efficiency through root modification, which might contribute to reduced use of P fertilizers, expanding agriculture on low-P soils, and achieving more sustainable agriculture.
