Phosphorus is an essential mineral nutrient element for plants, which plays an important role in the growth of plants. However, under normal circumstances, the effective phosphorus content in the soil is low, and the phosphate fertilizer applied to the soil is easily adsorbed and fixed as insoluble organic phosphorus, which cannot be directly absorbed by plants. . Root exudates play an important role in the transformation of soil phosphorus and are an important strategy for plants to adapt to low phosphorus. Under low-phosphorus conditions, plant roots can directly or indirectly affect the conversion of soil phosphorus by secreting organic acids, acid phosphatase, protons and sugars, and improve the availability of soil phosphorus. This article reviews the changes of plant root exudates under low phosphorus conditions and the mechanism of action of different root exudates on soil phosphorus transformation, revealing the influence mechanism of plant root exudates on soil phosphorus transformation under low phosphorus conditions, and further understanding Plant low-phosphorus adaptation strategies are of great significance.

Phosphorus is an essential mineral nutrient of plants and play an important role in plant growth, but usually the effective phosphorus content in soil is low, and the phosphorus fertilizer application into the soil is easy to be adsorbed and fixed as insoluble organophosphorus, which cannot be directly absorbed and utilized by plants. Root secretions play an important role in soil phosphorus conversion and are an important strategy for plant low phosphorus adaptation. Under the condition of low phosphorus, plant root system directly or indirectly affects the conversion of soil phosphorus by secreting organic acid, acid phosphatase, proton and sugar, and improves the effectiveness of soil phosphorus. This paper summarizes the mechanism of soil phosphorus conversion by the change of plant root secretions under low phosphorus and the mechanism of soil phosphorus conversion of different root secretions, and reveals the influence mechanism of plant root secretions under low phosphorus on soil phosphorus conversion, which is of great significance to further understand the strategy of plant low phosphorus adaptation.

Phosphorus is an essential mineral nutrient element for plants, which plays an important role in the process of plant growth. However, the content of available phosphorus in soil is usually low, and the phosphorus fertilizer applied to soil is easy to be adsorbed and fixed as insoluble organic phosphorus, which can not be directly absorbed and utilized by plants. Root exudates play an important role in soil phosphorus transformation, which is an important strategy for plants to adapt to low phosphorus. Under the condition of low phosphorus, plant roots directly or indirectly affect the transformation of soil phosphorus by secreting organic acids, acid phosphatase, protons and sugars, so as to improve the availability of soil phosphorus. In this paper, the changes of plant root exudates under low phosphorus and the mechanism of different root exudates on the transformation of soil phosphorus were reviewed. The mechanism of plant root exudates on the transformation of soil phosphorus under low phosphorus was revealed, which is of great significance for further understanding of plant low phosphorus adaptation strategy.
