Embodiment 1
[0021] Take 10 μg of total genomic DNA from mustard root, digest with restriction endonuclease Tail (MaeII*) at 65°C overnight, and stop the digestion reaction at 80°C for 20min. Dilute DNA concentration to 2ng / L, use T 4 DNA ligase performs self-cyclization reaction, using the cyclization product as a template, and performing nested PCR amplification with specific primers N2 / N3 and N1 / N4, respectively, to obtain a single sequence of about 800bp, T-cloning, and sequencing.
[0022] Referring to the operation manual of the Genome Walking Kit (TaKaRa) kit, 3 primers SP1, SP2, and SP3 were designed according to the full-length gene sequence of ChlRB7. Three rounds of nested PCR amplification were carried out sequentially with the total genomic DNA of Alpine mustard as a template, and a single fragment of 1282bp was obtained, which was sequenced by T-cloning and sequenced. The obtained fragment was highly homologous to the previous 800bp fragment sequence, and further analysis de...
