library_construction_protocol: Total RNA was extracted using the RNeasy micro kit (Qiagen, Hilden, Germany), with on-column DNase to remove contaminating genomic DNA. RNA concentration and purity were measured using NanoDrop 2000. (Thermo Fisher Scientific, Wilmington, DE). RNA integrity was assessed using the RNA Nano 6000 Assay Kit from the Agilent Bioanalyzer 2100 system (Agilent Technologies, Santa Clara, CA). A total amount of 1 μg RNA per sample was used as input material for the RNA sample preparations. Sequencing libraries were generated using NEBNext UltraTM RNA Library Prep Kit for Illumina (NEB, USA) following manufacturer's recommendations and index codes were added to attribute sequences to each sample, the library preparations were sequenced on an Illumina platform and paired-end reads were generated.
