细胞器、细胞以及源组织和库组织之间的代谢运输不仅能够协调途径，而且还促进整个植物的通讯，特别是在有关资源可用性的信息传输方面。碳同化与氮同化相协调，以确保生物质生产的组成部分、氨基酸和碳骨架以所需的量和化学计量提供，并通过相关的运输过程确保这些重要资源从合成地点运输到利用地点。在可能参与代谢和运输的有效协调的许多可能的翻译后机制中，仅详细描述了可逆的硫醇-二硫化物交换机制。蔗糖和海藻糖代谢在信号中枢中交织在一起，确保适当的资源分配，以在最佳和应激条件下驱动生长和发育，其中海藻糖 6-磷酸充当蔗糖可用性的重要信号。强大的植物代谢物转运蛋白套件在途径间协调和源库相互作用方面提供了巨大的灵活性和适应性。着眼于碳代谢网络，我们强调了不同转运蛋白家族的功能，以及硫氧还蛋白在源组织和库组织之间代谢对话中的重要性。此外，我们还讨论了如何定制这些系统以改善作物。代谢物运输不仅可以完美协调不同细胞器和细胞之间的途径，而且还可以平衡整个植物的能量供应和利用。植物代谢运输表现出巨大的可塑性和灵活的调控能力。本综述特别关注碳转运蛋白，讨论了源器官和汇器官中的转运功能，其中蔗糖和海藻糖在源-汇通讯中包含复杂的感知和信号系统。代谢物运输促进途径间调节、细胞间通讯以及源和库过程的协调。本综述强调碳代谢网络，重点关注转运蛋白、碳流和信号传导的作用。-探讨了蔗糖和海藻糖途径作为植物生长和信号传导调节节点的整合。
Metabolite transport between organelles, cells and source and sink tissues not only enables pathway co-ordination but it also facilitates whole plant communication, particularly in the transmission of information concerning resource availability. Carbon assimilation is co-ordinated with nitrogen assimilation to ensure that the building blocks of biomass production, amino acids and carbon skeletons, are available at the required amounts and stoichiometry, with associated transport processes making certain that these essential resources are transported from their sites of synthesis to those of utilisation. Of the many possible posttranslational mechanisms that might participate in efficient co-ordination of metabolism and transport only reversible thiol-disulphide exchange mechanisms have been described in detail. Sucrose and trehalose metabolism are intertwined in the signalling hub that ensures appropriate resource allocation to drive growth and development under optimal and stress conditions, with trehalose-6-phosphate acting as an important signal for sucrose availability. The formidable suite of plant metabolite transporters provides enormous flexibility and adaptability in inter-pathway coordination and source-sink interactions. Focussing on the carbon metabolism network, we highlight the functions of different transporter families, and the important of thioredoxins in the metabolic dialogue between source and sink tissues. In addition, we address how these systems can be tailored for crop improvement. Metabolite transport not only allows the flawless coordination of pathways in different organelles and between cells, but it is also balances energy provision and utilisation throughout the whole plant. Plant metabolite transport displays enormous plasticity and flexible regulation. Focussing particularly on carbon transporters, this review discusses transport functions in source and sinks organs, with sucrose and trehalose in source-sink communication that encompasses sophisticated perception and signalling systems. Metabolite transport facilitates inter-pathway regulation, cell to cell communication and co-ordination of source and sink processes. Highlighting the carbon metabolism network, this review focuses on the role of transporters, carbon flow, and signalling.- The integration of sucrose and trehalose pathways as nodes in the regulation of plant growth and signalling is approached.
