The single nucleotide polymorphism (SNP) in the DRD2 gene ( DRD2 C939T ) was genotyped by PCR restriction fragment length polymorphism (PCR-RFLP). Finally, to ensure the reliability of the
C. kwangsiensis RNA was used to construct cDNA libraries with fragment a length of 200 bp. Then, paired-end sequencing was performed using an Illumina HiSeq TM 2500 following the manu
