The CONSTANS target gene from Brassica napus was cloned, and the full length amplified primer of it was designed and amplified on the sequence released on NCBI. The target gene fragments were sequenced and the restriction loci were analyzed. The enzyme primers (BamHⅠ, SacⅠ) were designed, and the target gene fragments were connected to the eukaryotic expression vector pBI121 through BamHⅠ and SacⅠ double enzyme digestion. PCR identification result indicated that PBI121+CONSTANS overexpression vector was successfully constructed. The overexpression vector was transformed into the competent EHA105 cell, and the seeds of T0 were infected by Arabidopsis thaliana. The positive plants were screened by MS solid medium containing Cara (50 mg/L). PCR identification showed that PBI121+CONSTANS overexpression vector was successfully introduced into Arabidopsis thaliana and 12 transgenic positive seedlings were obtained, which did the preparation for the gene function analysis.
