title: RNA-Seq of zea mays: leaf primodium
design: Maize leaf primordium of about 5 mm were partitioned under dissection microscope into three parts: M3tip1.5 mm, M3middle2.5 mm, and M3base1 mm. Maize leaf primordium of about 3 mm were partitioned into two parts: M2top2 mm and M2base1 mm. About 200 leaf primordium and 10 leaf sheath of 1-2 mm were obtained, partitioned, and pooled into different samples with three biological replicates.
