RNA-Seq of  wild-type plant Mock -treated
Shortly, messenger RNA was isolated according to polyA selection method by oligo(dT) beads and then fragmented by fragmentation buffer firstly. Secondly double-stranded cDNA was synthesized using a SuperScript double-stranded cDNA synthesis kit (Invitrogen, CA) with random hexamer primers (Illumina).  Then the synthesized cDNA was subjected to end-repair, phosphorylation and A base addition according to Illuminas library construction protocol. Libraries were size selected for cDNA target fragments of 200300 bp on 2% Low Range Ultra Agarose followed by PCR amplified using Phusion DNA polymerase (NEB) for 15 PCR cycles.
