大豆磷、硫转运蛋白研究进展

磷、硫转运蛋白是大豆（Glycine max（L.）Merr.）体内磷、硫转运的重要载体，参与调节磷和硫酸盐的吸收与转运，对提高大豆的磷、硫利用效率至关重要。大豆磷转运蛋白可划分为Pht1、Pht2、Pht3、Pho1和Pho2 5大家族，目前对Pht1的研究最为深入。大豆14个Pht1家族可分为3个亚家族，他们对磷吸收和转运具有重要作用。大豆硫转运蛋白基因GmSULTR1；2b可在大豆根中特异性表达并被低硫胁迫诱导。本文基于大豆磷、硫的营养吸收、转运与利用过程中的相关性，对Pht1家族以及GmSULTR1；2b基因在大豆中的研究进展进行了综述，并对近年来大豆磷、硫转运蛋白的研究进展及未来的研究方向进行了展望。

Advances in research on Glycine max (L.) Merr. phosphate and sulphate transporters

Phosphate and sulphate transporters are important carriers involved in the absorption and transport of phosphate and sulfate in Glycine max (L.) Merr., which is essential for improving the utilization efficiency of phosphorus and sulfur in soybean. Phosphate transporter families are responsible for the absorption and movement of phosphate in plants and can be divided into five major families, i.e., Pht1, Pht2, Pht3, Pho1, and Pho2. At present, most research has been conducted on the Pht1 family of G. max phosphate transporters, which has indicated that Pht1 plays an important role in phosphate uptake and transport. The Pht1 family can be further divided into three subfamilies with 14 members. Furthermore, GmSULTR1;2b is a G. max sulphate transporter gene specifically expressed in roots and induced by low sulfur stress. Based on the correlation between nutrient absorption, translocation, and utilization of soybean phosphorus and sulfur, this paper reviews recent research progress on the Pht1 family and GmSULTR1;2b gene, as well as on phosphorus and sulfur transporters in soybean, with predictions given for future research directions.
