英文摘要	An important characteristic of arbuscular mycorrhizal (AM) symbiosis is the transfer of phosphate from AM fungi to plants. This transfer is facilitated by mycorrhiza-inducible phosphate transporter proteins. Lysophosphatidylcholine (LPC) stimulates mycorrhiza-inducible phosphate transporter gene expression. This study aims to detect the pattern of five Petunia hybrida phosphate transporter (PhPT1-5) genes associated with AM development and their response to LPC in petunia roots. Using the method of real-time reverse transcription-polymerase chain reaction (RT-PCR), we explored the transcriptional changes of PhPT1-5 genes. Our results reveal that the PhPT4 transcript level is enhanced by 8,320-fold at 40 days after inoculation in mycorrhizal roots compared with uninoculated roots. However, PhPT4 is depressed by LPC, which acts as a mycorrhiza signal in several mycorrhizal plants. Our results suggest that PhPT4 is a mycorrhiza-specific phosphate transporter and LPC is not always a universal signal in AM fungi-plant symbiosis.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000310326100023&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Biochemical Research Methods; Plant Sciences; SCI(E); 1; ARTICLE; 6; 1480-1487; 30
