豆科植物共生组织中磷酸盐转运的研究进展

Phosphate (Pi) is a key nutrient element essential for plant growth and development, and the dynamics of phosphate transport and metabolism across interfaces in legume-microbe (Rhizobium and arbuscular mycorrhizal fungi) interactions directly regulate the establishment and maintenance of symbiotic relationships. Current research focuses on the functional characterization of phosphate transport proteins in symbiotic systems and the analysis of transport pathways. In this study, we summarized the key proteins of phosphate transport in the symbiotic process, and elaborated the transmembrane phosphate transport mechanism in plant roots, rhizomes and mycorrhizal tissues, with the aim of analyzing the regulation logic of legume-microbe complex symbiosis, and at the same time, providing theoretical support for the efficient use of phosphorus resources by legumes, which has great significance for the promotion of sustainable development of agriculture and the enhancement of the efficiency of ecosystem phosphorus cycling. This is of great significance to promote the sustainable development of agriculture and enhance the efficiency of ecosystem phosphorus cycle.
