In plants, the uptake from soil and intercellular transport of inorganic phosphate (Pi) is mediated by the PHT1 family of membrane-spanning proton : Pi symporters. The Arabidopsis thaliana AtPHT1 gene family comprises nine putative high-affinity Pi transporters. While AtPHT1;1 to AtPHT1;4 are involved in Pi acquisition from the rhizosphere, the role of the remaining transporters is less clear. | Nội dung Text Arabidopsis PHOSPHATE TRANSPORTER1 genes PHT1 8 and PHT1 9 are involved in root-to-shoot translocation of orthophosphate
