Abstract
Description
The present invention relates to a set consisting of four primers for isothermal amplification reaction for detecting cucumber mosaic virus, a composition comprising the same, and a method for detecting cucumber mosaic virus using the composition.
Cucumber mosaic virus is a virus that infects lily, asteraceae, bacillus, and the like, and is a virus that contains foreign RNA in spherical particles having a diameter of 28 nm.
Cucumber mosaic viruses are very broad, with 39 or 117 species of hosts known to date, and weed or crops are widely distributed, so there are infectious sources everywhere. It is also transmitted non-exclusively by more than 80 species of aphids. It is very susceptible to infection by contact during the work because of the easy transmission of juice. There is no soil infection or seed transmission, but it is possible to spread the graft. Aphids are widely distributed throughout Korea, and in particular, they are susceptible to rapid spread by causing more than 80% of infections caused by peach aphids and cotton aphids. In Korea, silver or vinyl tape is installed in houses or open fields to prevent aphid deposits. However, since there is no treatment after the onset of the disease, there is no way to treat only the infected objects. The main host plants are the major crops such as tomatoes, eggplant, pepper, cucumber, melon, melon and lettuce, so the damage is great.
On the other hand, an electron microscope or a serological method was mainly used as a conventional virus diagnosis method. Electron microscopy can detect the presence of virus but it is almost impossible to diagnose the species as a morphological feature. Among the serological methods, ELISA (Enzyme-Linked Immunosorbent Assay) is about 1,000 times lower than the most commonly used diagnostic methods or Polymerase Chain Reaction (PCR) It is often the case that accurate diagnoses fail due to unexpected nonspecific reactions. In recent years, PCR methods with high detection sensitivity and convenience have been widely used for the diagnosis of viruses. However, it is very important to develop specific primers for the diagnostic method using PCR. It must be confirmed by electrophoresis and finally subjected to a sequence of DNA sequencing. In addition, this method requires specialized equipment such as a thermocycler and a professional manpower to operate it, and sequencing of the amplification product for final confirmation is a process requiring high cost and high technology. In addition, this process is time-consuming to perform and is not visually detectable. Therefore, the ability to use analytical equipment in the field is significantly reduced. In order to effectively detect the virus in such a short time, development of a method capable of real-time detection on the spot without professional equipments is required.
The isothermal amplification method (LAMP) is similar to the conventional PCR method, but the conventional PCR method repeatedly performs three steps of denaturation, splicing, and elongation to amplify the gene, The isothermal amplification method has the advantage of being able to bond and stretch at a fixed temperature. This is because the Taq DNA polymerase ( Taq DNA It is because the polymerase) may result in place of the nucleic acid ends hydrolysis (denaturation of the double helix of DNA without depending exonuclease) by using the Bst DNA polymerase (Bst DNA polymerase) that has a function that uses the heat. Therefore, isothermal amplification does not require a temperature change during amplification of the gene, which makes gene amplification possible at fixed temperature with no special equipment.
The inventors of the present invention have developed a primer set for isothermal amplification reaction that can detect various species of cucumber mosaic virus without any specialized equipment in the field as a result of studying for easy detection of cucumber mosaic virus which is a big problem in a farmhouse Thereby completing the present invention.

The present inventors have completed the present invention by studying a method for detecting cucumber mosaic virus in real time in a field without professional equipment in order to effectively detect cucumber mosaic virus in a short time.
The present invention provides a primer set for isothermal amplification reaction for detecting cucumber mosaic virus consisting of SEQ ID NOS: 1 to 4. The primer set of the present invention was prepared using a sequence of a coat protein (virion protein) as a template rather than a whole viral sequence. Coat protein is a protein that is essential for the virus to be made into an individual. It is known that some viruses are involved in the movement of viruses within the plant. That is, coat protein is used as a template because it is an unconditionally produced protein if the virus is infected. The genbank number of variants detectable by the present invention represents the full sequence of the virus variant. Sequences of the coat protein coding region of each mutant actually used in the preparation of the primer of the present invention are attached to the sequence listing.
The present inventors used loop-mediated isothermal amplification (LAMP) to detect cucumber mosaic virus in a short time without professional equipments. Unlike conventional polymerase chain reaction (PCR), the isothermal amplification method does not require temperature control to amplify the gene, so it can amplify the gene without specialized equipments and it is possible to amplify the gene at a high concentration in a short time. In order to use loop-mediated isothermal amplification (LAMP), four primers (F3, B3, FIP, and BIP) must act as one set, and F3 and FIP bind in five directions Primer, and B3 and BIP are primers that bind in the reverse direction in three directions. In addition, FIP and BIP are primers that contain the nucleotide sequence of F2 (or B2) and F1c (or B1c).
The present invention also relates to a method for producing a plant, comprising extracting total RNA (total RNA) from a plant; Performing a reverse transcription reaction using the whole RNA as a template to synthesize a total cDNA (total cDNA); Isothermal amplification reaction was carried out at 60 ° C to 65 ° C for 30 minutes to 2 hours using the above cDNA as a template using a primer set of the present invention, a DNA polymerase for isothermal amplification reaction, dNTPs, and a reaction buffer Amplifying the target sequence; And detecting the amplified product. The present invention also provides a method for detecting cucumber mosaic virus. DNA can be extracted directly from red pepper suspected of being infected, but it can also be applied to specimens and cultured cells that have been artificially infected for research purposes.
In one embodiment of the present invention, it has been confirmed that cucumber mosaic virus can be detected by performing isothermal amplification using the universal primer set of the present invention. When SYBR Green I is used at a concentration of 1,000 to 10,000 times, electrophoresis (See Example 4), under natural light, without going through the steps of FIG.

To detect CMV by loop-mediated isothermal amplification (LAMP), a primer was prepared using PrimerExplorer V4. In order to use the isothermal amplification method, four primers (F3, B3, FIP, and BIP) should act as one set. In order to detect all kinds of known CMVs, a common part between five kinds of CMV gene sequences is searched Primer was prepared using PrimerExplorer V4 mainly at the site of detection (Fig. 2). As shown in Fig. 3, a universal primer set which is expected to be applied to all viruses of CMV virus was prepared.
Example 3. Collection of plant specimens
Plant samples were collected to confirm that the primer set produced in Example 2 could be used to detect CMV. In the present invention, total RNA was isolated from virus-infected plant samples and then total cDNA was synthesized by reverse transcription.
The extraction buffer used for total RNA isolation was TRI REAGENT (catalog number: TR 118) from MRC. The plant tissue is placed in a mortar and the liquid nitrogen is added, and when the nitrogen is evaporated, the tissue is grinded to a fine powder and the tissue is extracted with 1 ml of extraction buffer using a spatula preliminarily cooled in liquid nitrogen Transferred to a tube. After putting the powdered tissue into the tube, the tube lid was closed and reacted at 4 ° C for 5 minutes. Then, 200 μl of chloroform was added thereto, followed by vigorous shaking for 15 seconds, followed by reaction at room temperature for 10 minutes or more. After reacting, centrifuge at 8,000 × g at 4 ° C for 10 minutes. Collect 500 μl of the supernatant using a pipette, carefully transfer it to a new tube, and add the same amount of isopropanol to the supernatant. The reaction was allowed to proceed at room temperature for 10 minutes. The reaction tubes were centrifuged at 4 ° C and 8,000 × g for 10 minutes to precipitate RNA. The pellet was washed with a mixture of ethanol and DEPC treated water (0.1% diethyl pyrocarbonate aqueous solution) in a ratio of 7.5: 2.5, and centrifuged at 4 ° C and 8,000 × g for 10 minutes. After removing the tube, the tube was placed upside down on the test tube holder, and the RNA pellet was dissolved in 30 μl of DEPC treated water. The concentration of RNA extracted through a spectrophotometer was measured.
Reverse transcription was performed to synthesize cDNA based on total RNA obtained from the above experiment. Reverse transcription was performed using M-MLV Reverse Transcriptase (BIONEER) and random primers according to the manufacturer's instructions. RT-PCR was performed by a 3-step method. The tubes containing total RNA and random primer were reacted at 70 ° C for 10 minutes, and then the temperature was lowered to 4 ° C. After adding dNTP and buffer, After 10 minutes of reaction, the temperature was lowered to 4 ° C, and the reaction was allowed to proceed at 37 ° C for 1 hour, followed by 10 minutes of enzyme inhibition at 70 ° C.
Example 4. Isothermal amplification and validation
To confirm that the primer set prepared in Example 2 was usable for detecting CMV, a primer composition for amplification reaction was prepared.
For the preparation of the primer composition, 2 uL of 10X (10X) Bst 10 mM dNTPs (dATP, 10 mM Tris-HCl, 10 mM (NH 4 ) 2 SO 4 , 10 mM KCl, 2 mM MgSO 4 , 0.1% Triton X- dTTP, dGTP, dCTP mixture was mixed by 10 mM each), 20 mM MgSO 4, 1 ul of 0.4 ul of 10 uM F3 and B3 primer, 1.6 ul of 10 uM FIP and BIP primer, 1 ul (8 Unit) Bst polymerase , 1 μl of 1/10 diluted template cDNA, and 11.5 μl of distilled water were added to the reaction tube and mixed. The prepared amplification reaction composition was reacted at 40 ° C. for 30 seconds and reacted in a reaction vessel at 62 ° C. for 1 hour and 30 minutes to perform isothermal amplification. After the reaction was completed, enzyme activity was inhibited at 80 DEG C for 5 minutes. 5 μl of the total 20 μl reaction was electrophoresed to confirm that the gene was amplified. The results are shown in Fig. As shown in Figure 4, the universal primer set 3 as the template of plants with CMV virus different in the case of using (turnip mosaic virus sulfide (Turnip yellow mosaic virus ; TYMV), fake virus 2 ( Broad bean wilt virus 2; BBWV2), sugar beet sulfide virus ( Beet western yellows virus ; BWYV) was performed by isothermal amplification method to detect only CMV. In the absence of viral gene (lane 5), the gene was not amplified. When CMV (lane 4) was used as a template, the CMV gene was amplified, but the gene was not amplified in other types of viruses (
Then, SYBR Green I concentrated to 1,000 times with the same reagent was added at a rate of 1 μl per 20 μl of the reaction, and the color development was confirmed by natural light. The results are shown in FIG. 5, and the result of color development reaction in ultraviolet light is shown in FIG. 6 . The significance was verified by comparing the results of the electrophoresis of SYBR Green I with the results of amplification of the viral gene. As shown in FIG. 5, even when the SYBR Green I was concentrated at a high concentration and the amplified gene (universal primer set sample) was stained, it was confirmed that the gene was amplified in the CMV infected strain and greens green under natural light. Samples infected with other viruses were found not to be green. As shown in Fig. 6, the result of coloring could be confirmed by green fluorescence on ultraviolet light.
From the above results, it was confirmed that the primer set used in this experiment can be used to specifically detect only CMV. In addition, when SYBR Green I is concentrated at 10,000 times, it is confirmed that the primer set can be visually observed under natural light I could.
