根分泌的有机酸使植物能够获得难溶于土壤的磷（P）。我们以前报道过，当大豆种植在蛭石在不溶性磷酸钙的存在下，作为磷源，硫（S）施肥增加有机酸分泌的根，提高磷的收购。在本研究中，我们证实，硫肥增加有机酸，如柠檬酸的分泌时，大豆种植在具有较强的磷固定能力的灰成土。相反，大豆根系中柠檬酸的浓度并没有增加硫肥。因此，研究硫营养与柠檬酸输出蛋白基因表达的关系，以了解S诱导柠檬酸分泌的机制。进一步验证了柠檬酸转运蛋白基因GmMATE13和GmMATE47的表达是否参与了硫肥诱导根系分泌柠檬酸的过程。与不施硫肥相比，施硫肥显著提高了GmMATE13在根中的表达水平。因此，我们的研究结果表明，S营养参与诱导GmMATE13的表达，并有助于从大豆根中分泌柠檬酸。
Organic acid secretion from the roots enables plants to acquire phosphorus (P) which is poorly soluble in soil. We previously reported that when soybeans were cultivated in vermiculite in the presence of insoluble calcium phosphate, as a phosphorus source, sulfur (S) fertilization increased organic acid secretion from the roots and improved P acquisition in soybeans. In the present study, we confirmed that S fertilization increased secretion of organic acids such as citric acid when soybeans were cultivated in Andosols having a strong P fixation capacity. In contrast, concentration of citric acid in soybean roots did not increase by S fertilization. Therefore, the relationship between S nutrition and gene expression of citric acid exporters was investigated to understand the mechanisms of induction of citric acid secretion by S. Further, we verified whether the expression of citric acid transporter genes,GmMATE13andGmMATE47, is involved in the induction of citric acid secretion from the roots by S fertilization. The expression level ofGmMATE13in roots was significantly increased by S fertilization compared to that without S fertilization. Therefore, our results suggest that S nutrition is involved in inducingGmMATE13expression and contributes to the excretion of citric acid from the soybean roots.
