摘要/Abstract

摘要：

磷素是植物必需的大量营养元素,植物对磷素的吸收和植物体内磷素的再度转运是位于细胞原生质膜上的磷转运蛋白介导的需能主动运输过程。概述了植物吸收和转运磷素的生理特征,植物磷转运蛋白(PT)的结构、功能和PT及磷调节子Pho基因的表达调控机制,以及突变体技术在植物磷吸收、转运中的研究进展和应用前景。旨在为今后在分子水平上进一步揭示植物对磷素吸收和转运的生物学机制提供理论依据。

关键词: 磷素吸收、转运;磷转运蛋白;结构;功能;表达调控

Abstract:

Phosphorus is one of the macronutrients in plants. The uptake of phosphorus and redistribution of phosphorus in plants are mediated by the phosphorus transporters located at the cytoplasm membrane in which the driving power was supplied by H+-ATPase conjugated with the phosphorus transporters. In this paper, the physiological characteristics of phosphorus uptake and transportation in plants, the structure, biological function of the phosphorus transporters in plant species and the expression regulation of the phosphorus transporter genes, and phosphorus-responsive genes (Pho regulon) were summarized. Meanwhile, the progress and potential value of plant mutants related to phosphorus uptake and transportation were evaluated. It is aimed to provide molecular basis for further exploring the molecular mechanism of phosphorus uptake and re-distribution in plants in the future.

Key words: phosphorus uptake and transportation, phosphorus transporter protein, structure, function, expressional regulation
