Phosphorus (P) is one of the most important macronutrients for plant growth and yield. Low availability of inorganic phosphate (Pi) in soil substantially curbs crop production, whereas excessive Pi fertilization causes economic and ecological problems. The rapid depletion of global rock phosphate (RP) reserves calls for efficient plant Pi-management. To cope with low Pi (LP) stress, plants have evolved morphological, physiological, molecular, and biochemical adaptations. Apart from arbuscular mycorrhizal fungi (AMF)-mediated Pi acquisition, Pi uptake, it's export, utilization, and remobilization depend on transport processes mediated by membrane bound PHosphate Transporters (PHTs), which are grouped into five families. Among these, the PHT1 family is the primary transporter involved in the acquisition of Pi from soil and redistribution within plants. In this review, we present a brief account on 5 PHTs (PHT1 to …
