title: mRNA-Seq_5-weeks_ros1 leaves_flg22
design: Arabidopsis Columbia (Col-0) plants were grown for two weeks on plates containing Murashige and Skoog (MS) medium (composition for a 1 L medium (pH = 5.7) : 2.3 g MS, 0.5% sucrose, 0.8% agar, 0.5 g MES, vitamins, 0.5% sucrose and 0.8 % agar, 0.5 g MES).  Seedlings were then transfered onto soil for 3 weeks. Plants were grown under 8 h light condition at 22.5  C and 16 h dark condition at 19,5  C (Percival growth chamber AR-36L2). Rosette leaves were syringe-infiltrated gently with either water or 1  M flg22 peptide.
