Description

Method for improving phosphorus utilization rate of wheat by using gene editing

Technical Field

The invention relates to a method for improving the phosphorus utilization rate of wheat by using gene editing, and relates to the field of gene editing.

Background

Phosphorus is one of the major elements necessary for plant growth and development. It is a main component of nucleic acid, nucleoprotein, phospholipid, adenosine triphosphate, etc. of plants, and also plays an important role in energy metabolism, photosynthesis, respiration, regulation of enzyme activity, redox reaction, signal transduction, carbon metabolism, etc. The lack of phosphorus can affect the formation of nucleoprotein, inhibit cell division and proliferation, reduce protein synthesis, block the transportation of sugar, finally cause the branch of the plant to be less, the stem and the root to be slender, the plant to be short and small, the flower and fruit to be easy to fall off and reduce the yield, etc. The growth and output capacity of plants are obviously dependent on the effectiveness of inorganic phosphorus (Pi), but the content of effective phosphorus in most soil is very low and is only 1-10 mu mol/L. Although the organic phosphorus in the soil can reach 80 percent, the organic phosphorus cannot be absorbed by plants, and the organic phosphorus must be converted into inorganic phosphorus before being absorbed and utilized (Schachtman et al, 1998; Holford, 1997). In agricultural production, phosphate fertilizer is commonly added to ensure normal growth and development of crops, and the global easy-to-harvest phosphate rock resource faces a crisis that has been eliminated in this century (Gilbert, 2009; Vance et al, 2003).

Wheat is an important food crop in China, and how to cultivate a low-fertilizer high-yield environment-friendly wheat variety is a great challenge for wheat breeders. Plants have developed mechanisms to cope with the severe deficiency of available phosphorus in the agricultural natural ecosystem over a long period of evolution. Therefore, the gene for fully exploiting the phosphorus with high efficiency in the wheat has important guiding significance for improving the molecular breeding with low phosphorus, high efficiency, environmental friendliness and sustainable yield increase.

Under Low phosphorus stress, the growth of the main Root of arabidopsis thaliana is inhibited, and in an arabidopsis thaliana mutant with LPR1(Low phosphorate Root1) losing function, the growth of the main Root is normal. LPR1 encodes multicopper oxidases (multicopper oxidases) that control the growth of the main roots by regulating the expression levels of scr (scarecrow) and SHR (Short-root), which slow down growth and increase the number and length of lateral roots under low phosphorus stress (svistonoff et al, 2007). Homologous genes of these genes can be found in rice, maize, wheat, sword bean and white lupin, suggesting that root architecture changes in plants that respond to low phosphorus stress may have similar regulatory pathways.

Disclosure of Invention

The LPR2 gene is located on chromosome four 4A, 4B and 4D in wheat and is named TaLPR2-4A, TaLPR2-4B and TaLPR2-4D respectively. The genome sequence is 1972, 1957 and 1940 bases in the whole length of 4A, 4B and 4D, and the three homologous genes are composed of 3 exons and 2 introns.

Based on this genetic information, we cloned the TalPR2-4A gene in Fielder using homologous cloning and submitted it to NCBI under GenBank accession number MK 676068. The similarity of the coding regions among the three homologous genes is very high, and the characteristic provides a theoretical basis for synchronously silencing the TaLPR2 gene of the three sites by using a gene editing technology.

In practical application, the gene conversion process can realize the silencing of LPR2 gene at genome level, and is a powerful tool for improving the utilization rate of phosphorus in wheat by using genetic engineering technology.

Claims (7)

1. A pBUE411-LPR2 binary vector with the function of knocking out wheat LPR2 gene is characterized by comprising an expression cassette A and an expression cassette B;

the expression cassette A specifically comprises the following elements from upstream to downstream in sequence: the TaU3 promoter A from wheat, the sgRNA of the LPR2 gene and the terminator A; the sequence of the promoter A is shown as SEQ ID NO: 3 is shown in the specification; the DNA sequence of sgRNA of the LPR2 gene is shown in SEQ ID NO: 10 is shown in the figure;

the expression cassette B specifically comprises the following elements from upstream to downstream in sequence: the promoter B, the maize Cas9 coding sequence and the terminator B, wherein the sequence of the promoter B is shown in SEQ ID NO: 4 is shown in the specification; the maize Cas9 coding sequence is set forth in SEQ ID NO: 13 is shown in the figure; the terminator A sequence is shown as SEQ ID NO: 5 is shown in the specification; the terminator B sequence is shown as SEQ ID NO: and 6.

2. The pBUE411-LPR2 binary vector of claim 1, wherein said expression cassette a sequence is specifically set forth in SEQ ID NO: 7 is shown in the specification;

the sequence of the expression box B is specifically shown in SEQ ID NO: 8 is shown in the specification;

the expression cassette A is located at the upstream of the expression cassette B, and the expression cassette A and the expression cassette B are connected in series.

3. The pBUE411-LPR2 binary vector of claim 2, further comprising a resistance marker gene; the nucleotide sequence of the pBUE411-LPR2 binary vector is shown as SEQ ID NO: shown at 9.

4. The method for constructing the binary vector pBUE411-LPR2 according to claim 1, comprising the steps of:

s11 designs sgrnas targeting LPR2 gene, and primers corresponding to oligonucleotides of the sgrnas are as set forth in SEQ ID NOs: 1, LPR2-gR1-TaU3-F shown in SEQ ID NO: 2 LPR2-gR1-TaU 3-R;

s12 phosphorylates and anneals 2 oligos of the synthesized sgRNA to form double chains;

s13, utilizing restriction enzyme BsaI to cut the pBUE411 vector, and recovering vector fragments containing the promoter A, the terminator A, the promoter B and the terminator B;

s14 the recovered pBUE411 carrier fragment and double-stranded sgRNA with sticky ends are connected by T4 ligase to obtain the final pBUE411-LPR2 binary carrier.

5. The use of the pBUE411-LPR2 binary vector of any one of claims 1-4 to increase phosphorus utilization in wheat.

6. Use of the pBUE411-LPR2 binary vector of claims 1-4 in breeding transgenic wheat.

7. A method for improving phosphorus utilization rate of wheat by using gene editing is characterized by comprising the following steps: the function of the wheat LPR2 gene is reduced or lost, and the expression and/or activity of the protein coded by the wheat LPR2 gene is inhibited, so that the phosphorus utilization rate of the wheat is improved;

the method for reducing or losing the function of wheat LPR2 gene is to construct pBUE411-LPR2 binary vector as described in any one of claims 1-5.
