Follow the provisions of GB/T19495.1 and GB/T19495.3. Alternatively, a plant-based solid tissue DNA extraction kit with the same effect can be used for DNA template preparation.
SDNA concentration determination
Use ultraviolet spectrophotometry to determine the DNA concentration. Dilute the DNA solution appropriately, measure its absorbance at 260nm, and calculate the DNA concentration based on the measured OD value (1OD at 260nm = 50pg/mL double-stranded DNA). The OD value should be in the range of 0.2--0.8. Measure its absorbance at 280nm, and calculate the ODzmam/ODmm ratio of the DNA solution based on the measured OD value. The ratio should be between 1.8 and 2.0
6.6 Real-time fluorescence PCR detection
6.6.1 Setting of negative control, positive control and blank control. The non-transgenic sample is used as the negative control. The corresponding transgenic plant sample strain or the genomic DNA of the transgenic plant sample containing the corresponding exogenous gene, or the plasmid standard molecule DNA containing the above fragment is used as the positive control, and water or TE buffer is used as the blank control. 6.6.2
Real-time fluorescence PCR reaction system
The PCR reaction system is shown in Table 3 or prepared according to the recommended system of the kit that has been verified to meet the requirements. Prepare 2 parallel tubes for each DNA sample. When adding samples, the sample DNA should be completely added to the reaction solution without sticking to the tube wall. The tube cap should be tightly closed as soon as possible after adding samples. Table 3

PCR reaction parameters
iiiKAa~cJouaKAa
Real-time fluorescence PCR amplification parameters: 50C/2min: 95C/10min: 95C/15s.60C/60s, greater than or equal to 40 cycles.
Note: 95C /10min is specially suitable for hot start Ta enzyme with chemical conformational change. The above parameters can be adjusted according to different models of real-time fluorescence PCR instrument and the selected PCR amplification reagent system.
SPCR reaction operation
Place the PCR reaction tubes on the real-time fluorescence PCR instrument in sequence. Before loading the instrument, check whether the reaction tubes are tightly covered to prevent light leakage and contamination of the instrument. Start running the instrument for real-time fluorescence PCR reaction. 7. Result analysis
7.1 Threshold setting
After the real-time fluorescence PCR reaction is over, set the fluorescence signal threshold. The threshold setting principle is adjusted according to the instrument noise situation, and the threshold line just exceeds the highest point of the normal negative sample amplification curve. 7.2 Quality control
Blank control: The internal reference gene detection does not show a typical amplification curve, all exogenous gene detections do not show a typical amplification curve, or the value is greater than or equal to 40.
Expression control: The internal reference gene detection shows a typical amplification curve, and the value is less than or equal to, all exogenous gene detections do not show a typical amplification curve, or the threshold value is greater than or equal to 40. Positive control: The detection of the internal reference gene shows a typical amplification curve, and the Ct value is less than or equal to 30; the detection of all exogenous genes shows a typical amplification curve, and the Ct value is less than or equal to 34. 8 Result judgment and expression
8.1 Result judgment
If all the test samples are reacted in parallel, the detection of the exogenous gene does not show a typical amplification curve or the C value is greater than or equal to 0: The detection of the endogenous gene shows a typical amplification curve, and the Ct value is less than or equal to 30, it can be judged that the sample does not contain the exogenous gene tested. If all the test samples are reacted in parallel, the detection of the exogenous gene shows a typical amplification curve, and the Ct value is less than or equal to 36. The detection of the endogenous gene shows a typical amplification curve, and the Ct value is less than or equal to 30, it can be judged that the sample contains the corresponding exogenous gene. If all the test samples are reacted in parallel, the detection of the exogenous gene shows a typical amplification curve, but the Ct value is between 36 and 40, and the Ct value of the endogenous gene detection shows a typical amplification curve and is less than or equal to 30, the sample should be reprocessed and tested on the machine after eliminating contamination. After re-amplification, if the endogenous gene detection shows a typical amplification curve, and the Ct value is less than or equal to 30, and the exogenous gene detection shows a typical amplification curve, and the t value is still less than 40, it can be determined that the sample contains the exogenous gene to be detected. After re-amplification, if the endogenous gene detection shows a typical amplification curve, and the Ct value is less than or equal to 30, and the exogenous gene detection does not show a typical amplification curve, or the Ct value is greater than or equal to 40, it can be determined that the sample does not contain the exogenous gene to be detected.

No exogenous gene was detected in the sample.
