library_construction_protocol: Seeds were sown on MS medium containing 0.8% m/v agar, stratified for four days in the dark at 4°C, and then transferred to continuous white light at 22°C. After nine days of growth, entire seedlings were collected and total RNA was purified using the QIAGEN RNeasy Plant Mini Kit following the manufacturer's protocol. cDNA libraries were generated based on the Illumina TruSeq RNA Sample Preparation Guide. Polyadenylated mRNA was extracted from 3 μg of total RNA and then fragmented. Reverse transcriptase SuperScript II (SSII RT) (Thermo Fisher Scientific, Waltham, MA, USA) and random hexamers were used to synthesize cDNA. Finally, specific adapters were added to each sample and the libraries were sequenced on the Illumina GAIIx platform with 100 bp reads. Reads were analyzed using version 1.3 of the Illumina pipeline and underwent quality filtration using standard Illumina procedures.
