Manganese (Mn) is an essential heavy metal micronutrient in plants having a range of cellular functions. Mn homeostasis involves the coordinated operation of transporters mediating cellular import and export and distribution between cell organelles. Significant progress has been made in identifying transport mechanisms in plants responsible for Mn uptake from the soil, distribution around the plant and compartmentalisation within the cell. These processes are required to ensure that Mn reaches its correct target proteins and also for cellular Mn detoxification. Transporters that have been implicated in Mn transport include members of the P2A-type ATPase, ZIP, CAX, CDF, NRAMP and OPT/YSL families. Here we discuss their roles in the acquisition, distribution and homeostasis of Mn and aspects of their regulation.
