Phosphate and sulfate are two macro-elements essential for plant growth and development. Both elements play a central role in numerous aspects of plant metabolism and their deficiencies have profound effects on the transcriptome as well as on numerous metabolic pathways. The research emphasis so far has been on elucidating the molecular physiology of these individual nutritive elements. Recent data proved the existence of complex connections between the various regulatory layers of the homeostasis of these elements, but the molecular bases and biological significance of such interconnections remains poorly understood. This review provides an update on recent advances to identify the components involved in phosphate and sulfate homeostasis crosstalk. In light of this case study, developing a comprehensive understanding of the coordination of the ion homeostasis and identifying genes which can be used as good molecular markers for monitoring the “integrative ionic status” of plants is not only of great scientific interest, but also crucial for biotechnological and agronomic applications.
磷酸盐和硫酸盐是植物生长和发育所必需的两种主要元素。这两种元素在植物代谢的许多方面都起着核心作用，它们的缺乏对转录组以及许多代谢途径都有深远的影响。迄今为止，研究的重点一直是阐明这些单个营养元素的分子生理学。最近的数据证明了这些元素的内稳态的各种调节层之间存在着复杂的联系，但这种相互联系的分子基础和生物学意义还知之甚少。本文综述了最近在鉴定参与磷酸盐和硫酸盐内稳态相互作用的组分方面的进展。有鉴于此，深入了解离子内稳态的协调，并确定可作为监测植物“综合离子状态”的良好分子标记的基因，不仅具有重要的科学意义，而且对生物技术和农业应用也至关重要。
