title: GSM2028157: Root_Pi-_polyA-_Rep1; Arabidopsis thaliana; RNA-Seq
library_construction_protocol: The total RNAs were extracted with the Trizol reagent (Invitrogen). After total RNA extraction, ribosomal RNAs were removed using RiboMinus™ Plant Kit repeated two times. The poly(A)+ and poly(A)- constituent were separated with oligo(dT) magnetic beads (Oligotex mRNA Mini Kit, QIAGEN). dUTP based strand-specific library construction protocol
