Roles, Regulation, and Agricultural Application of Plant Phosphate Transporters.

Phosphorus (P) is an essential mineral nutrient for plant growth and development. Low availability of inorganic phosphate (orthophosphate; Pi) in soil seriously restricts the crop production, while excessive fertilization has caused environmental pollution. Pi acquisition and homeostasis depend on transport processes controlled Pi transporters, which are grouped into five families so far: PHT1, PHT2, PHT3, PHT4, and PHT5.

Establishment of a gene function analysis system for the euhalophyte Salicornia europaea L.
