The effects of sucrose on the growth,phosphorus uptake in rice under phosphate deficient conditions were studied.The results showed that exogenous sucrose can increase the biomass of rice,promote the absorption of phosphorus in rice under phosphate deficiency.Using phosphate transporter gene OsPT2 promoter +GUS reporter gene transgenic rice,we further explored the molecular mechanism that the uptake and use of phosphate was promoted in rice by sucrose under phosphate deficiency.The results showed that rice phosphate transporter OsPT2 was involved in this process.
