title: CLN
design: Total RNA was isolated separately from primary dormant, nn-dormant, secondary dormant seeds using RNAiso Plus and RNAiso-Mate for Plant Tissues (TAKARA, Dalian, China). The interegraty and quantity of total RNA were assessed using a BioAnalyzer. Then, cDNA library was prerared and pair-end sequencing was performed using the Illumina HiSeq 2500 platform.
