Description

Rye stripe rust resistance gene and application thereof
Technical Field
The invention belongs to the field of plant genetic engineering, and relates to a rye SECCE Rv1G0452990 stripe rust resistance gene and application thereof.
Background
Wheat (Triticum aestivum L.) is one of the important grain crops in China, and the maintenance and improvement of the yield are important guarantees of the national grain safety. Wheat stripe rust (WHEAT STRIPE rust) is a common disease of wheat production and is a foliar disease caused by Puccinia striiformis westend.f. sp. The most pronounced feature of stripe rust is the production of pronounced yellow or orange spores in the leaves, generally aligned along the veins. 88% of the wheat production area of the world is easy to be infected by stripe rust, the wheat yield is reduced by 500 ten thousand tons due to the stripe rust each year, the lost economic value is as high as 10 hundred million dollars (see reference :Colin,R,Wellings.Global status of stripe rust:a review of historical and current threats.Euphytica.2011,179:129-141). China is one of the largest stripe rust epidemic areas in the world, four pandemics have occurred since the country was built, and the yield loss is about 130 hundred million kilograms respectively in 1950, 1964, 1990 and 2002 (see reference :Wan A,Zhao Z,Chen X,et al.Wheat stripe rust epidemic and virulence of Puccinia striiformis f.sp.triticiin China in 2002.Plant Disease,2004,88:896-904).. Therefore, the breeding of the stripe rust resistant wheat variety and the excavation and utilization of disease resistant genes have important significance for guaranteeing the national grain safety).
Modern breeding aimed at high yield greatly weakens the genetic diversity of crops, and loss of genetic diversity not only limits further improvements in yield and quality, but also makes it difficult for crops to cope with global climate change and pest epidemic. The related species of wheat contain a plurality of excellent genes and are important genetic resources for genetic improvement of common wheat. Therefore, the introduction of a useful gene of a wheat closely related species into a conventional cultivated wheat is one of important and effective ways of improving wheat varieties.
Rye (SECALE CEREALE l.), a annual or perennial herbaceous crop of the genus lolium of the family gramineae, is one of the wild kindred species of wheat. Rye is a diploid species whose genome is RR. Rye has excellent characters lacking in common cultivated wheat and is an important wild germplasm resource for genetic improvement of common wheat. Triticale is a new species artificially synthesized by wheat (Triticum) and rye (Secale) species via intergeneric sexual crosses and doubling of hybrid chromosome numbers. The wheat hybrid rice combines the characteristics of high yield and quality of wheat, disease resistance and cold resistance of rye, high lysine content and the like, has huge hybrid growth advantages, and can be used as feed, brewing, biological energy and grain. The triticale obtained by doubling diploid rye by crossing with wheat of different ploidy has mainly six ploidy (AABBRR) and eight ploidy (AABBDDRR) 2 types.
There is no literature report on the research content of the stripe rust resistance gene sequence and molecular markers in triticale Rozovskaya-7.
Disclosure of Invention
According to the invention, the two triticale parents Rozovskaya-7 and 4100 are respectively expressed as near immunity and high sense by inoculating and identifying the physiological race CYR32-34 of the stripe rust. The F1 is obtained after crossing two triticale parents, and the F2 group is obtained after selfing. 200 single plants in the F2 group are inoculated and identified, 144 plants are found to be resistant to diseases and 56 plants are found to be high in sense. And respectively selecting 40 extreme disease-resistant and 40 extreme disease-sensitive materials from the F2 population to form an anti-pool and a sensitive pool, taking leaves to extract total RNA, sequencing, and finding that the stripe rust resistance gene is positioned at the tail end of 6RL of rye through BSR (Bulk SEGREGANT RNA sequencing) analysis. 11 co-dominant Indel markers were developed near 6RL using two parental resequencing data, and the stripe rust resistance gene was further mapped to the 1.25Mb interval (corresponding to Lo7 reference genome 6r:878.556-879.809 Mb) using fine mapping with F2 consisting of 1246 individuals. Subsequently 24 genes in the interval were analyzed in combination with anti-pool sensory pool transcriptome data, and 19 genes were found to have FPKM <1 in both anti-pool and sensory pool, possibly pseudogenes. The other 5 genes only had SECCE expression levels of the Rv1G0452990 in the anti-pool higher than in the sensory pool, thus SECCE Rv1G0452990 was identified as a candidate gene. Using the rye reference genome sequence (https:// ftp.ebi.ac.uk/ensemblgenomes/pub/release-56/plant/fasta/secale _ cere ale/dna /), the SECCE6Rv1G0452990 sequence in Rozovskaya-7 was cloned and a specific molecular marker 6R2990-1 was developed. To verify SECCE6Rv1G0452990 function, genetic transformation with stripe rust-sensitive wheat as a receptor material is performed by using an overexpression vector of SECCE6Rv1G0452990, and a transgenic result shows that the over-expression of SECCE6Rv1G0452990 can improve the resistance of wheat to stripe rust, and the result shows that SECCE6Rv1G0452990 is a stripe rust resistance gene.

Definition of the definition
GISH: genomic in situ hybridization techniques (genomic in situ hybridization) developed based on fluorescence in situ hybridization techniques. The technique employs total genomic DNA from one species as a label probe, and is blocked with total genomic DNA from another species at an appropriate concentration, and in situ hybridization is performed on the target chromosome. Between the blocking DNA and the labeled DNA probes, the blocking DNA preferentially hybridizes with non-specific sequences, the remaining specific sequences are hybridized mainly by the labeled probes, and finally, the chromosome sets, chromosomes or chromosome fragments of different sources are detected.
Inoculation identification: healthy triticale seedlings are cultivated in a greenhouse, inoculated by a method of manually scattering stripe rust spores, and wheat plants are subjected to moisturizing, illumination cultivation and the like to attack diseases so as to identify stripe rust resistance of the material.
Near immunity and high feel: according to the resistance degree of wheat varieties to stripe rust, the disease resistance of wheat varieties can be classified into six grades of immunity, high resistance, medium feeling and high feeling. Immunization did not produce any visible spore pile on the leaves. Near immunity is the appearance of small dead spots on the leaves, which do not produce a spore stack. The high sense is that the spores on the leaves are large and much, and the periphery is not green.
Extreme disease resistance and extreme disease susceptibility: the research of disease resistance inheritance mainly adopts a Mendelian analysis method, namely, hybridization of disease resistance and disease-sensitive plants is carried out, and the disease resistance separation condition of offspring is analyzed. In the F2 separation group, the most disease-resistant material is the extremely disease-resistant material, and the most disease-resistant material is the extremely disease-resistant material.
BSR: the mixed population separation analysis method (Bulked SEGREGANT ANALYSIS, BSA) is a rapid method for positioning the target trait genes by using an extreme trait individual mixed pool. In the segregating population, offspring DNA of extreme characters are selected and mixed in equal quantity, library construction and sequencing are respectively carried out on a mixed gene pool (GenePool) and parents, the Frequency (AF) of sequencing data of different libraries in polymorphic Sites (SNP) is calculated, and correlation is carried out on the sequencing data and a target phenotype, so that gene positioning or linkage molecular marker development related to the target characters is realized.
Co-dominant markers: meanwhile, dominant and recessive alleles can be detected, and the genetic markers of homozygous and heterozygous genotypes can be distinguished.
Indel label: insertion-deletion (InDel) refers to the insertion or deletion of nucleotide fragments of different sizes in the sequence at the same genomic locus between closely related species or different individuals of the same species, i.e., one or more bases in one sequence at a position that is homologous to another sequence. The InDel polymorphism molecular marker is a marker for PCR amplification by designing specific primers based on sequences at two sides of an insertion/deletion site, and the marker belongs to a length polymorphism marker in nature, and can be typed by using a convenient electrophoresis platform.
Ubiqutin promoter: ubiquitin (UBQ or Ubi) gene promoters, which are constitutive promoters, show significantly higher levels of gene expression in most tissues and many cell types of plants, especially in monocotyledonous plants (e.g. maize), and are often used to drive the overexpression of a gene.
Specific molecular markers: the specific molecular marker is developed based on functional Single Nucleotide Polymorphism (SNP) or insertion and deletion (InDels) loci in a gene sequence, and has the advantages of high selection efficiency, co-dominance, co-separation with a target gene, no influence of genetic background and the like.
FPKM: FPKM (FRAGMENTS PER Kilobase of exon model per Million FRAGMENTS MAPPED) is a commonly used method of quantifying gene expression, and is used to measure the level of expression of a gene (or transcript). FPKM is a formula for measuring the relative expression of genes. FPKM is the number of fragments aligned to a gene divided by the number of all sequences aligned to the genome (in Million) and the length of RNA (in KB).
Genome re-sequencing: methods for sequencing the genomes of different individuals from species whose genomic sequences are known. For analysis of differences between the genomes of different individuals, such as the discovery of single nucleotide polymorphism sites, insertion deletion sites, structural variation sites, copy number variation sites, and the like.
1BL/1RS translocation line: refers to wheat-rye translocation chromosomes formed by translocation of the short arm of the 1R chromosome of rye to the long arm of the wheat 1B chromosome. As the short arm of 1R is provided with genes for resisting wheat leaf rust, stem rust, stripe rust and powdery mildew, the germplasm containing 1BL/1RS is widely applied to the breeding of wheat in the world.

Detailed Description
The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent.
Example 1 identification of rye stripe rust resistance genes
The inventor uses the stripe rust physiological race CYR32, CYR33 and CYR34 (inoculated on a stripe rust identification platform of the national academy of sciences of China and development biology) to carry out mixed inoculation (the inoculation method refers to a powder spraying method in 3.3 wheat stripe rust propagation and preservation section in national standard NY/T1443.1-2007. In actual operation, the inoculation effect is judged by the disease condition of a disease control material), and three mixed physiological races of CYR32, CYR33 and CYR34 are found to be near-immune and high-sense respectively by two triticale parents Rozovskaya-7 (saved by Han Fangpu laboratories of the national academy of sciences of China and development biology) and 4100 (provided by Ni Zhongfu professor of national academy of agriculture). To clone the stripe rust resistance gene in Rozovskaya-7, two triticale parents were crossed to give F1 and selfed to give F2 populations. 200 single plants in the F2 group are inoculated and identified, 144 plants are found to be resistant to diseases and 56 plants are found to be high in sense. And respectively selecting 40 extreme disease-resistant and 40 extreme disease-sensitive materials from the F2 population to form an anti-pool and a sensitive pool, taking total RNA extracted from leaves for sequencing (carrying out transcriptome sequencing at An Nuo reach gene technology company), and finding that the stripe rust resistance gene is positioned at the tail end of 6RL of rye through BSR (Bulk SEGREGANT RNA sequencing) analysis. 11 co-dominant Indel markers were developed near 6RL using genome re-sequencing data of ten times the sequencing depth of the two parents, and the stripe rust resistance gene was further mapped to the 1.25Mb interval (corresponding to Lo7 reference genome 6r:878.556-879.809 Mb) using F2 progeny obtained after crossing of the two parents, which is a population for gene mapping, with disease resistance: 3:1, for fine mapping. Subsequently 24 genes in the interval were analyzed in combination with anti-pool sensory pool transcriptome data, and 19 genes were found to be FPKM <1 in anti-pool and sensory pool, possibly pseudogenes. The other 5 genes only had SECCE.sup.6Rv1G 0452990 expression levels in the anti-pool higher than in the sense pool and higher (Table 2), and therefore SECCE.sup.6Rv1G 0452990 was determined as candidate genes.
Table 1 shows the statistics for the group Rozovskaya-7 and 4100F2 stripe rust identification. The total inoculation of 200 strains, 144 disease-resistant strains and 56 high-sensitivity strains basically accords with the separation ratio of 3:1.
