%X 大豆是主要的粮食和经济作物，作为油脂、蛋白质及保健活性物质的重要来源，发展潜力巨大。根系是植物吸收土壤养分、水分的最主要器官，养分和水分主要通过根系的直接截获或者通过质流、扩散到根表后被根系吸收。磷是作物生长发育不可缺少的营养元素，但它在土壤中有效性是非常低的，低磷胁迫是限制大豆产量最主要的因素之一。在磷亏缺的土壤中大豆根系会产生一系列适应性的变化，选育适应低磷胁迫环境和高效吸收利用土壤中有限的有效磷的大豆品种已经成为当前的研究热点，本文分别从低磷胁迫坏境下，大豆根系的形态改变、根系生理生化的适应性变化和响应低磷的分子研究进展进行了初步概述，对大豆耐低磷品种的高效选育进行了展望，以期为我国大豆耐低磷品种高效的遗传育种研究提供参考。<br />
Soybean is the main food and economic crop, and as an important source of oil, protein and health active substances, it has great development potential. Root system is the most important organ for plants to absorb soil nutrients and water. Nutrients and water are mainly absorbed by root system after being intercepted directly by root system or diffused to root surface through mass flow. Phosphorus is an indispensable nutrient for crop growth and development, but its availability in soil is very low. Low phosphorus stress is one of the most important factors limiting soybean yield. In the phosphorus-deficient soil, soybean root system will produce a series of adaptive changes. Breeding soybean varieties that adapt to low phosphorus stress environment and efficiently absorb and utilize the limited available phosphorus in soil has become the current research hotspot. The adaptive changes of root physiology and biochemistry and the molecular research progress in response to low phosphorus were summarized, and the high-efficiency breeding of soybean varieties with low phosphorus tolerance has been prospected, so as to provide a reference for the high-efficiency genetic breeding of soybean varieties with low phosphorus tolerance in China.
