The Arabidopsis seedlings treated with 2μM t-zeatin (CTK) for 30 minutes and then total RNA was extracted from Arabidopsis seedlings using TRIzol reagent (Invitrogen) and treated with RNase-free DNase I. The poly(A) mRNA was isolated using oligo (dT) beads. First-strand cDNA was subsequently generated using random hexamer-primed reverse transcription, followed by synthesis of the second-strand cDNA using RNaseH and DNA polymerase I. Then, single-end and paired-end RNA-seq libraries were prepared following Illumina's protocols and sequenced on the Illumina GA II platform.
