Gene expression profile of leaf in rice grown under paddy field with macronutrient deficiencies

Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice leaves under nitrogen (N), phosphorus (P), and potassium (K) deficiency conditions in paddy field to obtain a global view of gene regulations associated with plant response to essential nutrients. We performed microarray analysis of rice grown under N, P and K deficiency and control conditions in the paddy field, respectively. Leaf samples were collected at 1 week-interval under nutrient deficiency and control conditions, and obtained a total of 36 microarray data. For the gene expression profile, the uppermost fully-expanded leaf in the main stem was sampled at 12:00 PM.
