An overview of the expression profile of all genes in root from rice seedlings under nitrogen (N), phosphorus (P) and potassium (K) deficiency conditions. The 7-day old seedlings were exposed to N, P and K deficiency treatments and control condition, respectively. Root samples were collected at 6 and 24 hours after the treatments (Details of methods
). The RNA isolated from a total of 24 samples in three replicates were labeled with Cy3 and used for hybridization using the Agilent one-color microarray analysis system (Sample list
). The expression profile for each gene is shown as raw signal intensity and normalized signal intensity (log2).
