RNA-Seq of Camellia crassicolumna
Fresh, mature and healthy leaves were collected and then frozen in liquid nitrogen. Total RNA was extracted from these frozen leaves using the Spectrum Plant Total RNA Extraction Kit (Sigma-Aldrich, Burlington, MA, USA), the cDNA library preparation and 2  150 bp paired-end sequencing was performed at Novogene, China. Transcriptome sequencing library construction, Illumina HiseqXten sequencing, raw data cleaning and quality control were performed at Novogene, China.
