Abstract:The phosphate transporter named CoPht1;1 was isolated from oil tea(Camellia oleifera’Xianglin4’)with the method of RT-PCR and RACE. Its expression under different phosphorus level at different time was checked with qRT-PCR. The CDS of CoPht1; 1 is 1 626 bp in length and it codes a predicted protein of 542 amino acids. The amino acid identity compared with other phosphate transporters is highly conserved and shows the highest similarity(88%)with the CoPht1;1 of Catharanthus roseus. Putative secondary structure and topology of the encoding protein have the main feature of transmembrane protein, and is consistent with Pht1 encoding protein in other species. The real-time RT-PCR result showed that expression of CoPht1;1 is induced by P-deficiency,and varied at different time. The results showed that CoPht1; 1 play an important role in phosphate uptake in camellia.
