The purpose of this RNA Sequencing project was to investigate the transcriptional regulatory relationship between NF-YC3/4/9, NF-YB2/B3 and CO-SAIL. Methods: Total RNA was isolated, and then poly-A purified. 100ng of starting RNA was used to generate RNASeq libraries using the NEXTflex Illumina qRNA-Seq Library Prep Kit, and sequenced on an Illumina HiSeq2500 machine. Results: NF-YC3/4/9, NF-YB2/B3 and CO-SAIL have both shared and independent regulatory targets. Overall design: mRNA profiles of 7-day old Wild Type (WT), nf-yc triple (Q3), nf-yb3/b3, and CO-SAIL seedlings grown in continuous white light were generated from two biological replicates through paired end deep sequencing on an Illumina HiSeq2500 platform.
