主　　题：rice phosphate transporter abiotic stress subcellular localization expression profile 

摘      要：The transport of phosphate between cytoplasm and subcellular compartments is critical for plant metabolic *** conducted bioinformatic analysis,heterologous expression in yeast,gene expression pattern and subcellular localization analysis to characterize the possible functions of OsPHT4 gene family in *** with the PHT4 genes from higher plants,OsPHT4s can be classified into six distinct ***4;1-OsPHT4;4 are targeted to chloroplasts,and OsPHT4;6-1 and OsPHT4;6-2 are located to Golgi ***4 proteins can mediate inorganic phosphate(Pi)transport in *** addition,dynamic transcriptional changes determined by qRT-PCR revealed different expression profiles of OsPHT4 genes in response to phosphate starvation,salicylic acid,abscisic acid and salt stress *** results suggested that OsPHT4 proteins are involved in Pi distribution between the cytoplasm and chloroplast or Golgi apparatus and also involved in stress responses.
