Example 1
The screening method of the primer group comprises the following steps:
1) an index file was constructed on a database of genome sequences of 300 rice BLAST germs using the formatdb command in the BLAST toolkit provided by the National Center for Biotechnology Information (NCBI). Selecting a genome sequence which is most completely assembled as a query sequence, comparing the query sequence with a genome sequence database of 300 rice blast germs by using BLASTN software (the version number is 2.9.0), outputting the sequence in the format of-outfmt 1, setting the maximum output sequence number to be 300, and aligning all genome sequences in the genome sequence database.

Example 2
Two different rice blast germs with monoclonal sources are separated from two different rice areas in Hunan, and the numbers of the rice blast germs are respectively 1 and 2, wherein the number 1 rice blast germs are divided into two parts, and the numbers of the two parts are respectively 1-1 and 1-2. Thus, Pyricularia oryzae nos. 1-1 and 2 are different, Pyricularia oryzae nos. 1-2 and 2 are different, and Pyricularia oryzae nos. 1-1 and 1-2 are the same.
The application of the primer group in identifying the rice blast germs comprises the following steps:
s1, amplifying the detection sites of the genomic DNA of the rice blast germs to be detected and the control rice blast germs by using the primer group through multiple PCR to obtain multiple PCR amplification products.
In this example, all primer sets from site 1 to site 100 in Table 1 were synthesized and mixed by the United states thermal company, the primer sets included a forward primer and a reverse primer, and the sequences of the primer sets were shown in SEQ ID NO. 1 to SEQ ID NO. 200 in the sequence Listing. And amplifying the detection sites of the genomic DNA of the rice blast germs to be detected and the control rice blast germs by utilizing the primer group through multiple PCR, wherein the detection sites comprise a plurality of base sites with single nucleotide polymorphism. Specifically, genomic DNA of rice leaf numbers 1-1, 1-2 and 2 was multiply amplified 3 times in total according to an amplicon kit (cat # 4475345) produced by U.S. thermal power corporation, and the procedure was performed according to the instructions of the kit to obtain multiplex PCR amplification products.
S2, carrying out high-throughput sequencing on the multiple PCR amplification product to obtain a sequencing fragment.
In this example, a high-throughput sequencing library was constructed using an amplicon construction kit (cat 4475345) produced by thermoelectric corporation and the obtained multiplex PCR amplification products, and the procedures were described in the specification of the kit. 3 constructed libraries are mixed together to form a high-throughput sequencing library, and the constructed high-throughput sequencing library is subjected to high-throughput sequencing by using an S5 high-throughput sequencer produced by the United states of America, wherein the operation steps are carried out according to the specification of the kit, each Pyricularia oryzae sample is set as a 1M (1M is 1000000) sequencing fragment in the depth of the high-throughput sequencing, and the length of the high-throughput sequencing is set as 300 bp. The number of sequencing fragments obtained for samples 1-1, 1-2 and 2 was 1.1M, 0.9M and 0.9M, respectively. Thus, the average number of sequencing per detection site per sample was close to 10000 on average.
S3, obtaining the genotype of the detection site according to the sequencing fragment.
In this example, the obtained sequencing fragments were compared with the reference genome of Pyricularia oryzae with a version number of magnaporthe _ oryzae _70-15 using Bowtie2 software (version number: 2.1.0) and its default parameters, and only the sequencing fragments covering the complete sequence between the amplification starting point and the end point listed in Table 1 in the reference genome of Pyricularia oryzae were retained; the combination of the allelic type of the SNP in the reserved sequencing fragment, which is different from that of the reference genome, forms the MNP genotype of the sequencing fragment; the MNP genotype that has the greatest number of sequencing fragments in a detection site is referred to as the genotype of that detection site. For example, in the detection site AMPL3589924 of sample 1-1, the starting point 242345 of the amplicon in chromosome Supercontig _8_1 is set as position 0, the 35 th and 187 th bases are different from the reference genome and are both A, so the MNP genotype is marked as A (35) A (187), and the MNP genotype of total 9898 sequencing fragments is A (35) A (187), which is the largest in number, so A (35) A (187) is the genotype of the detection site AMPL 3589924. In the same manner, the genotypes of the detection sites AMPL3589924 of samples 1-2 and 2 were obtained as A (35) A (187) and C (35) C (187), respectively. Therefore, in the detection site AMPL3589924, the genotypes of samples 1-1 and 1-2 are the same, the genotypes of samples 1-1 and 2 are different, and the genotypes of samples 1-2 and 2 are different. In the same manner, it was judged whether the genotypes of each of the test sites were the same among the samples 1-1, 1-2 and 2.
S4, judging whether the Pyricularia oryzae to be detected and the Pyricularia oryzae contrast are the same or not according to the genotype of the detection site; if the genotype of the to-be-detected Pyricularia oryzae is the same as the genotype of the reference Pyricularia oryzae, judging that the to-be-detected Pyricularia oryzae is the same as the reference Pyricularia oryzae; and if the genotype of the to-be-detected Pyricularia oryzae is not completely the same as the genotype of the reference Pyricularia oryzae, judging that the to-be-detected Pyricularia oryzae is different from the reference Pyricularia oryzae.
In this example, the genotypes of all the commonly detected 90 detection sites of samples 1-1 and 1-2 were the same; 35 detection sites in 95 detection sites detected together in the samples 1-1 and 2 have different genotypes; of the 92 detection sites detected together in samples 1-2 and 2, 35 genotypes were not identical. Therefore, it is determined that the Pyricularia oryzae 1-1 to be tested is the same as the Pyricularia oryzae 1-2 of the control, the Pyricularia oryzae 1-1 to be tested is different from the Pyricularia oryzae 2 of the control, and the Pyricularia oryzae 1-2 to be tested is different from the Pyricularia oryzae 2 of the control. The result is consistent with the real situation, which shows that the method for identifying the rice blast germs is accurate.
By utilizing the method, the genome DNA is directly extracted from the rice leaves containing the rice blast germs to identify the rice blast germs, so that the separation work of the rice blast germs is avoided, and compared with the methods of whole genotype group sequencing and field inoculation identification, the method greatly saves manpower and material resources; the number of detection sites reaches 100, so the detection fineness is far greater than that of a method based on 1 or a few detection sites, such as an ITS (alternate transcription region) marker and other methods, for example, the ITS marker method can only identify the rice blast fungus, while the method can distinguish 1-1 and 2 and 1-2 and 2 different strains below the rice blast fungus, so the species identification distinguishing capability is stronger; the invention adopts a sequencing method, can know the composition of each base of each locus, and further enhances the fineness of species identification; the sequencing method is the 'gold standard' of any gene detection, so the accuracy of the method is superior to the SSR marker detection method or the SNP marker detection method based on electrophoresis and chip hybridization; because the method only detects 100 sites on the genome, but not every site on the whole genome, the average sequencing time of every detection site is close to 1 ten thousand times, which is far higher than that of the whole genome under the same sequencing cost, and the accuracy of detection is further remarkably improved; the invention mixes all 100 primers together, therefore, the working efficiency is improved by 100 times compared with a method based on single-site or few-site amplification, such as an SSR labeling method or an SNP labeling method. In fact, in this embodiment, only 3 times of multiplex amplification and one time of high-throughput sequencing are performed to detect 3 rice blast pathogen samples, and the working efficiency is greatly improved.
The application of the primer group in identifying Pyricularia oryzae provided by the invention is characterized in that multiple PCR amplification is carried out on multiple regions of genomic DNAs of Pyricularia oryzae to be detected and Pyricularia oryzae to be controlled by adopting the primer group to obtain an amplification product, the amplification product is detected by high-throughput sequencing, multiple (25-96) SNP sites are obtained in each division and are constructed into MNP (multiple Nucleotide polymorphism) genotypes, and whether the Pyricularia oryzae to be detected and the Pyricularia oryzae to be controlled are the same or not is identified by utilizing the MNP genotypes. The invention solves the defects of the existing rice blast germ identification method, and comprises the following steps: by utilizing multiple amplification and high-throughput sequencing, hundreds of marker sites can be detected at one time, and each marker site is repeatedly sequenced hundreds of times, so that the detection accuracy is improved, and the detection workload is greatly reduced; the multiplex amplification primers can be added and reduced at any time, the cost of single sample detection cannot be increased, and the identification flexibility is greatly increased; the detection cost of a single sample is also obviously reduced compared with the whole genome sequencing and chip technology.
