Plants have evolved various strategies to cope with common in nature phosphorus deficiency. Efficient inorganic phosphate (Pi) acquisition and distribution system within the plant and between cellular compartments is the most important of them. Amount and variety of transporters involved in this process indicates the complicity of Pi transport system in plants. In this work membrane transporters involved in Pi acquisition from soil (Pht1), Pi transport from root to shoot (Pht2) are characterized. Some proteins which seem to take part, or regulate this process, are also described.
