Abstract: Phosphorus (Pi) is one of the major nutrients for higher plant growth and development, Recently studies show that plant phosphate transporters mediate the uptake and translocation of this nutrient within plants. Under conditions of Pi starvation, the major mechanism for Pi uptake by roots is usually considered to be the high affinity system. And the majority of the plant PTs belong to the Pht1 family. In this paper, the research progresses of rice phosephate transporters Pht1 on expression regulation and biological properties in last decade were reviewed.
