Description

Fusarium proliferatum specific detection target FPRO-09882 and application thereof
Technical Field
The invention belongs to the technical field of gene detection, and particularly relates to a specific detection target FPRO-09882 of a layered Fusarium (Fusarium proliferatum) and application thereof.
Background
Fusarium proliferatum (F. proliferum) can infect crops such as rice, wheat, corn, asparagus, garlic, onion and the like and woody plants such as rhododendron, camellia oleifera, camellia, cedar and the like to cause root rot. The layered fusarium can grow on a PDA (personal digital assistant) plate, the morphological characteristics of the layered fusarium can be similar to those of fusarium verticillioides F.verteticiloides, bacterial colonies are circular after being cultured for 5 days at 25 ℃, the bacterial colonies are often aggregated into bundles, central mycelia grow vigorously, peripheral mycelia grow sparsely, the mycelia are changed from white to light yellow, and the central mycelia show a light purple shape in the later period. The large conidia are in a fusarium shape or a spindle shape, colorless and transparent, slightly bent, gradually tapered towards two ends, and provided with 2-5 diaphragms, the size of the small conidia (24.2-46.7 mu m) is 1.5-3.7 mu m, the small conidia are observed to be in a long oval shape or an elliptical shape under a microscope, colorless and transparent, the size of the small conidia (4.4-8.4 mu m) is 1.2-3.1 mu m), no diaphragm or one diaphragm exists, the conidia are stringed or pseudocephalic, the pair of spore chains is in a V shape, the number of pseudocephalic is short, the number of single phialides or multiple phialides is large, and the number of multiple phialides is large. No chlamydospore was produced. Under artificial culture conditions, the optimal growth temperature of the strain is 25 ℃, the optimal growth pH value is 5-7, conidia can germinate well when the relative humidity is 100%, and the lethal growth temperature of the strain is 60 ℃ for 10 min. The carbon source with good growth of the germs is soluble starch, and the nitrogen source is ammonium chloride. The optimum growth temperature of the Fusarium proliferatum is 25 deg.C, and the growth of hypha at a high temperature of above 35 deg.C is inhibited. The disease is wide in distribution, serious in harm, difficult to control and difficult to distinguish caused disease history symptoms, and is one of the most serious diseases in plant production. When environmental conditions favor the occurrence of root rot, the plant can be caused to produce a substantial reduction in yield or be dead. The root rot caused by Fusarium proliferatum is a kind of soil-borne disease, and occurs at home and abroad.
In recent years, molecular detection methods for Fusarium species have been developed. In 2010G mu ue et al used a part of calmodulin gene sequences (calmodulin gene sequences) to design specific primers for Fusarium delavayi (F. proliferum) isolated from Asparagus officinalis, and detected by general PCR. Huofang et al, in 2009, isolated Fusarium proliferatum (F. proliferum) from Camellia oleifera root rot, and designed specific primers according to ITS, with a sensitivity of up to 1pg, and a sensitivity of up to 100ag after nested pcr amplification. Riikka Peltomaa et al detected Fusarium in food in 2016 using Fusarium sensors, species-specific capture and detection probes, bound to the IGS region. The oligonucleotide functionalized magnetic microbead is used for capturing target DNA, and then the target DNA is detected by using a biotinylated detection probe and a streptavidin coupled label, wherein the detection sensitivity of the oligonucleotide functionalized magnetic microbead on Fusarium proliferatum (F.pr oliferatum) can reach 2.0 pg. In 2012, Jonathan and the like design a probe of real-time fluorescence quantitative PCR by using Cal gene, and the sensitivity can reach 11 pg. Yan Wang et al utilized the TEF-1 alpha region as the target of LAMP detection in 2020, and the minimum detection concentration of the target gene was 10pg by SYBR Green I visual evaluation and agarose gel electrophoresis detection. Maria et al designed a probe for real-time fluorescent quantitative PCR based on TEF gene and could be used to infect Fusarium proliferatum in early stage of rice seed. The primers designed in these methods are mainly derived from conserved genes such as the transcribed spacer (ITS) or TEF gene. These regions or genes are high copy in the genome and are therefore easily detected. However, more and more researches show that the ITS sequences of part of phytophthora species have small difference, and primers designed by using the sequence as a target are difficult to distinguish different species. The specificity and sensitivity of different target sequence detection have certain difference, and the result has great difference due to different selected target sequences and different fragment sizes. Therefore, the discovery of target genes with good specificity is the core of the current detection technology of Fusarium japonicum.

Therefore, after the primer designed in the embodiment 1 is used for carrying out the RPA amplification reaction, the detection result of the LFD lateral flow chromatography test strip shows 2 brown bands, and the target band is analyzed, so that Fusarium proliferatum can be effectively detected. While other fungi and oomycetes only have a brown band in the quality control area, and the negative control only has a brown band in the quality control area.
Example 3

The RPA detection time is only 30min, expensive instruments such as a PCR instrument and the like are not needed, the operation procedure is simple and convenient, and the method is more favorable for popularization and application in production.
Example 4
The DNA of the diseased pine needles inoculated with fusarium is extracted by adopting an NaOH alkaline lysis method and is used as a template for PCR amplification. Using 1uL of the DNA solution, the RPA-LFD assay was performed in the same manner as in example 3. The results are shown in fig. 6, which shows the test results as 1 from the left to the right, and the DNA extracted from fusarium solani (f. proliferatum) was used as a positive control; 2-4 artificially inoculating DNA extracted from pine needles (Cedrus dedara) of Fusarium (F.proliferum); 5-7 DNA extracted from pine needles (Cedrus deodara) artificially inoculated with agar blocks; 8 DNA extracted from pine needles (Cedrus deodara); 9 sterile water (negative control).
After RPA amplification reaction, the detection result of the LFD lateral flow chromatography test strip shows that the diseased pine needles (2, 3 and 4) inoculated with the layered fusarium can display 2 brown bands, and the target bands are analyzed and can effectively detect the layered fusarium. While other fungi and oomycetes only have a brown band in the quality control area, and the negative control only has a brown band in the quality control area.
