Problems solved by technology

[0006] There is no report on the expression of OR gene of A. chinensis at home and abroad, so real-time fluorescent quantitative PCR was used to study the expression of different CO 2 The expression characteristics of the OR gene of A. chinensis under the concentration treatment, the results showed that with the CO 2 With the increase of concentration, the expression of OR gene in both male and female worms increased, which was consistent with the trend of up-regulation of transcriptome expression, indicating that CO 2 Elevated concentrations can affect the expression regulation of OR genes

Embodiment 1

[0058] Handling of Test Material

[0059] In the control CO 2 Concentration (420μL·L -1 ) and high CO 2 Concentration (750μL·L -1 ) in the artificial climate box to cultivate the hollow lotus, which is used to raise the male and female A. chinensis. Different CO 2 Nine female and male worms with different concentrations were collected into Eppendorf tubes, and divided into three biological replicates, with a total of 12 groups of samples. After the worm samples were collected, they were quickly fixed in liquid nitrogen and stored at -80°C for later use.

Embodiment 2

[0061] Primer design

[0062] (1) Primer design: According to the sequence of the OR gene of A. chinensis obtained by transcriptome sequencing, DNAMAN software was used to design specific primers suitable for fluorescent quantitative PCR detection. The primer sequences are as follows:

[0063] OR-F:5`-ATCCTTACTCAATTCTGGACTTCC-3`

[0064] OR-R: 5`-TGCTTATCTCATGCTGGACAA-3`

[0065] The length of the fluorescent quantitative PCR product of the OR gene of A. chinensis is 105 bp, and the result of agarose gel electrophoresis shows that the amplified product has the same length and is a single band, indicating that the designed primers have strong specificity. Suitable for real-time fluorescent quantitative PCR detection, agarose gel electrophoresis results such as figure 1 shown.

[0066] (2) At the same time, according to the sequence of the A. chinensis tubulin gene obtained by transcriptome sequencing, primers for the internal control of fluorescent quantitative PCR were des...

[0071] Extraction of total RNA

[0072] Refer to Quanshijin's TransZol TM Extract the total RNA according to the instructions of the Up Plus RNA Kit kit, grind the worms into powder with liquid nitrogen, add 1ml TransZol TM Up, transfer to a 1.5 ml centrifuge tube, let stand at room temperature for 5 minutes, then add 200 μL chloroform / 1 ml TransZol TM Up, shake vigorously for 30 s, and incubate at room temperature for 3 min. After centrifugation at 10,000 g at 4°C for 15 min, transfer the upper aqueous phase (generally <80%) to a new centrifuge tube, add 1 / 3 volume of absolute ethanol, and gently invert to mix. Put the RNA spin column in a 2 ml collection tube, transfer all the mixture from the previous step into the spin column, centrifuge at 12000 g for 30-60 s, discard the mobile phase, and reuse the collection tube. Add 500 μLCB9, centrifuge at 12,000 g for 30 s at room temperature, discard the mobile phase, then add 500 μLCB9, centrifuge at 12,000 g for 30 s at ...

Abstract

The present invention provides primers and methods for detecting the OR gene transcription level of A. lotusiae. The sequence of the primers is shown in SEQ ID NO.1-2. 2 Fluorescent quantitative PCR method for detection of OR gene expression after concentration-cultivated A. japonicus, and sequencing of the transcriptome, compared the expression trend of OR gene fluorescence quantification with the expression trend of the transcriptome. The defense mechanism and OR gene expression characteristics of Orthosteraster under environmental stress laid the foundation.

Description

technical field [0001] The invention relates to a primer and a method for detecting the OR gene transcription level of A. chinensis, belonging to the field of biotechnology. Background technique [0002] A. chinensis is one of the main bio-defense natural enemies of A. japonicus. George Vogt discovered for the first time in 1962 that A. chinensis had a good control effect on A. chinensis. Afterwards, A. chinensis was widely used in the control of A. japonicus in the United States, Australia and other places, and achieved good control effect. In 1986, my country introduced A. chinensis from the United States and applied it to the biological control of A. chinensis. It has achieved certain success in Sichuan, Zhejiang, Fujian, Guangxi and other places. [0003] Insects are diverse and widely distributed in various environments. Some insects are beneficial to humans, while others seriously affect human production and life. Insects use sensitive chemosensory systems to detec...
