Gene expression data of winter wheat root under drought stress for 7 days by two phosphorus treatments

A complex regulatory network is the mechanism of wheat roots responding to drought stress at low and adequate phosphorus levels. The transcription levels of genes encoding silicon transporters, phosphate transporters, sucrose synthesis, etc., are mostly up-regulated in Xindong20. The genes encoding the electron transport chain and the respiratory chain are mostly down-regulated in Xindong23. These results suggest that wheat roots should maintain the structural integrity of the cells and reduce the energy metabolism during the coupled stress of drought and low phosphorus, which will help to improve the drought tolerance of wheat. The objective of the present data was to increase the information about the effect of drought on the transcriptomes of wheat root cultured by two phosphorus levels. To study the transcriptional responses of two winter wheat (Xindong20 and Xindong23) roots under drought stress during two phosphorus (conventional phosphorus level (CP: 1.0 mmol /L) and low phosphorus level (LP: 0.05 mmol /L)) treatments. The total RNA of the root sampled from two phosphorus treatments at 7d under drought stress was extracted and carried out the following gene chip experiments. Additionally, three biological replicates were performed in this study to reduce the errors caused by biological differences and ensure the accuracy and reliability of gene chip data.
