title: RNA-Seq of Quercus suber: pollen tissue
design: RNA-seq library preparation and sequencing was performed by Beijing Genomics Institute BGI (Hong-Kong, China). cDNA synthesis and paired-end library were prepared following the protocol of Illumina® TruSeq RNA Library Preparation kit for normalized libraries. This sample was sequenced in one lane using the Illumina HiSeqTM 4000 platform with a read length of 100nt.  Raw reads were cleaned by removing adaptor sequences, empty reads and low quality sequences.
