[0022] Experimental Example 1: Cloning of the BjCBP1 gene of BjCBP1
[0023] 1 Main reagents: column type small amount plant total RNA extraction kit (W7021) was purchased from Shanghai Huashun Biotechnology Co., Ltd.; DNA purification and recovery kit was purchased from Tiangen Biochemical Technology Co., Ltd.; 5'-Full RACE Kit kit , M-MLV Reverse Transcriptase, Premix Ex Taq, DL2000DNA Marker, and pMD19-T vectors were all purchased from Dalian Bao Biological Engineering Co., Ltd.
[0024] 2 Experimental methods and steps:
[0025] Acquisition of BjCBP1 gene sequence fragment SEQ ID NO.4: The total RNA of the tuber mustard stem was extracted by using the column type small amount plant total RNA extraction kit method, and a small part of the total RNA was detected by UV spectrophotometer for OD260 / OD280 The ratio of 1.92, the brightness of 28S by agarose gel electrophoresis is about 2 times that of 18S, indicating that the RNA has high purity and no degradation, which meets t...
