Embodiment Construction

[0041] 1. PCR amplification of the side sequence of the transgenic rapeseed Rf1 event exogenous insertion vector

[0042] First preheat 20% SDS to 65°C, take 15ml SDS extraction buffer (0.1TrisHCl, 0.05MEDTA, 1M NaCl pH8.0) and add it to a 50ml centrifuge tube, then add 2.5μl β-mercaptoethanol, mix well; grind with liquid nitrogen About 3g of leaves, transfer the powder to 50ml of 50ml centrifuge tube containing extraction buffer, shake and mix on the shaker, add 2ml of preheated 20% SDS, mix well, 65 ℃ water bath for at least 30 minutes, during which it should be light Shake the test tube gently; after the water bath, quickly place the centrifuge tube on ice, add 3ml 3M KAc, mix well, and place on ice for 30 minutes; centrifuge at 5000g at 4°C for 5min; transfer the supernatant to a new 50ml centrifuge tube, add 2 / 3 volume of isopropanol, mix well, place at -20°C for more than 30min; centrifuge at 6000g, 4°C for 15min, pour off the supernatant, wash with 75% ethanol, dry in v...

Abstract

The present invention discloses flanking sequence of exogenous event inserting vector for transgenic rape Rf1 and its application, and relates to bioengineering technology. The present invention obtains flanking sequence, SEQ No. 1, of exogenous event inserting vector for transgenic rape Rf1 with transgenic rape Ms1Rf1 as material. Of the flanking sequence, the 1-330 places bases are the same of that of the inserted vector sequence, and the 331-1116 places bases have no homology with that of the inserted vector sequence and are rape genome sequence. The present invention establishes the specific quantitative and qualitative detection method of exogenous event for transgenic rape Rf1 for the other specific event PCR detection of transgenic rape Ms1Rf1.

Description

technical field [0001] The invention relates to the detection of transgenic rapeseed in the technical field of bioengineering, in particular to a side sequence of an exogenous insertion vector of an exogenous gene integration event Rf1 of transgenic rapeseed and its application. Background technique [0002] In recent years, genetically modified crops such as corn, soybean, cotton, rapeseed and tomato have been approved to be planted and produced in many countries, and some have been processed into food, feed or used as food additives. Since the ecological safety and food safety of genetically modified products have been controversial, more than 30 countries and regions have successively implemented genetically modified product labeling systems. [0003] According to the sequence information of the exogenous gene in the transgenic product, the combination of the exogenous gene on the transgenic construct, and the integration site of the construct on the genome, gene-specific...
