Summary: In plants, the phytohormone cytokinin plays a major role in promoting cell division. However, the molecular mechanisms underlying cytokinin stimulated cell proliferation remain poorly understood. Here we show that, in the meristems of Arabidopsis thaliana, two transcriptional factors, MYB3R1 and MYB3R4, are master regulators of mitotic cell cycle gene expression and cytokinin response. Overall design: RNA-seq was carried out using dissected inflorescence meristems.

Library Construction Protocol: After the QC procedures, mRNA from eukaryotic organisms is enriched using oligo(dT) beads. For prokaryotic organisms or eukaryotic organisms' long-non-coding libraries, rRNA is removed using the Ribo-Zero kit that leaves the mRNA. First, the mRNA is fragmented randomly by adding fragmentation buffer, then the cDNA is synthesized by using mRNA template and random hexamers primer, after which a custom second-strand synthesis buffer (Illumina) , dNTPs, RNase H and DNA polymerase I are added to initiate the second-strand synthesis. Second, after a series of terminal repair, A ligation and sequencing adaptor ligation, the double-stranded cDNA library is completed through size selection and PCR enrichment.The qualified libraries are fed into Illumina sequencers after pooling according to its effective concentration and expected data volume.
