title: RNA-Seq of medicago truncatula : Macronutrient Deficiencies (Low Phosphorous)
design: RNA-seq libraries were prepared from root and shoot tissues of plants grown under sulfur (S), potassium (K), nitrogen (N) and phosphorus depleted conditions. The response to persistent deficiency was tested by growing the plants for 3 weeks under full nutrition (FN) or under deficiency of N, P, K or S. Additional samples were collected from plants re-supplied with FN for 6 h following the nutrient-deficiency treatment.
