Description

Upland cotton transformation event C006-10-13 and its specific identification method

technical field

The invention belongs to the field of biotechnology, and in particular relates to an upland cotton transformation event C006-10-13 and a specific identification method thereof.

Background technique

The transformation event is a molecular structure composed of the upstream and downstream flanking regions of the exogenous gene at the genome insertion site and the exogenous gene. Usually, a plant transformed with an exogenous gene can obtain a population of transformants comprising a large number of independent events, each of which is unique. The expression of exogenous genes in plants is influenced by the chromosomal location where the exogenous genes are inserted. This may arise from the influence of chromatin structure or transcriptional regulatory elements near the integration site. The expression levels of the same gene in different transformation events can vary widely, and there may also be differences in the spatial or temporal patterns of expression. Moreover, the insertion of exogenous genes may also affect the expression of endogenous genes. Thus, each independent transformation event affects recipient plants differently. Obtaining plant transformation events that can effectively express exogenous genes without affecting the agronomic traits of the plant itself has important application value in the cultivation of new varieties of transgenic crops.

my country is the world's largest producer and consumer of cotton, as well as the largest producer and exporter of textiles and clothing. The total cotton production accounts for about 25% of the world's cotton production. The rise and fall of cotton production has a certain impact on the development of my country's national economy and even the improvement of people's living standards. Cotton is one of the crops most seriously damaged by pests. There are at least 300 kinds of cotton pests in my country. Before the cultivation of transgenic insect-resistant cotton (i.e. cotton bollworm-resistant), the cotton aphid, cotton bollworm, cotton spider mite and cotton red bollworm were the most serious pests, and the annual loss of cotton production due to insect damage was 15% to 20%. %, the annual cost of pesticides for pest control is as high as 1200-1800 yuan per hectare. With the widespread planting of BT cotton and the substantial reduction in the amount of pesticides used in the field, the Lepidoptera pests such as cotton bollworm have been fundamentally and effectively controlled. However, a series of changes have taken place in the ecosystem of the cotton field. While effective control has been achieved, the number of non-target pests such as cotton aphids, mirid bugs, and whitefly has increased significantly, and they have gradually risen to become the main pests in cotton fields, especially mirid bugs, which have caused huge losses to cotton production.

In 2007, Huang Dafang submitted the Cry51Aa1 protein isolated from the Bt strain F14-1 and the Cry51Aa1 gene sequence encoding the protein to NCBI GenBank with the accession number DQ836184. The Cry51Aa1 protein is one of the parasporal crystals produced by Bacillus thuringiensis , has important application prospects in the field of biological control. The inventors of the present invention conducted site-directed mutation and in vitro virulence test research on the Cry51Aa1 gene, and screened and obtained the Cry51Aa1.C006-1 gene with strong anti-migus bug characteristics.

The pollen of the first cotton is removed by hand or human action in the afternoon before flowering, and the stigma of the flower is covered with a wax tube to prevent foreign pollen from contacting the stigma. When the pollen of the second cotton loosens in the next morning, pass Humans manually collect pollen from the second cotton and contact the pollen with the style or stigma of the first plant to complete the hybridization process. Wherein, when the first cotton is C006-10-13 in the embodiment, the second cotton is other cotton, or the second cotton is C006-10-13, and the first cotton is other cotton.

The hybrid bolls are harvested in the floc opening stage, and the cotton is naturally dried, ginned, and towed with concentrated sulfuric acid to obtain hybrid seeds. Planting to obtain hybrid offspring, which is the offspring of C006-10-13 breeding.

2. Selfing

One day before flowering, use grafting clips to directly clamp the flower buds of C006-10-13 or tie the flower buds with thin wires to prevent external pollen from contacting the stigma of C006-10-13 during flowering; or cover the entire cotton plant with a mesh bag It can effectively prevent pollination by insects and the like, and can realize self-pollination of cotton. Self-crossing can be accomplished through the above steps.

The hybrid bolls were harvested at the boll opening stage, and the cotton was naturally dried, ginned, and towed with concentrated sulfuric acid to obtain selfed seeds, planted, and selfed offspring were obtained, which were the offspring of C006-10-13 breeding.

2. Identification of traits of breeding offspring of C006-10-13 and analysis of its agronomic traits

(1) Identification method of traits of C006-10-13 breeding offspring

Use the genomic DNA of the offspring bred by C006-10-13 as a template, and use specific primers for PCR amplification. DNA molecules synthesized by the amplification technology), indicating that the offspring of C006-10-13 have the same traits as C006-10-13, if the PCR amplification product does not contain the amplicon of C006-10-13, it means that the C006-10-13 Breeding offspring do not have the same traits as C006-10-13. The specific identification method is as follows:

1. Identification method 1

(1) Using the genomic DNA of the offspring bred by C006-10-13 as a template, a primer pair consisting of primer 5 and primer 22 was used for PCR amplification to obtain a PCR amplification product.

The PCR amplification system was as follows: 10 μl of 2×MASTRE PCR MIX, 0.5 μl of primer 5 (10 μM), 0.5 μl of primer 22 (10 μM), 1 μl of template DNA (50 ng/μl), 8 μl of ultrapure water, and a total volume of 20 μl.

The PCR reaction conditions were as follows: 94° C. for 5 min; 32 cycles of 94° C. for 30 s, 55° C. for 30 s, and 72° C. for 45 s; 72° C. for 5 min.

(2) Perform agarose gel electrophoresis on the PCR amplification product obtained in step (1), and then make the following judgment: if the PCR amplification product contains a DNA fragment of about 500bp, it means that the offspring bred by C006-10-13 contain C006- 10-13 amplicon, the C006-10-13 breeding offspring has the C006-10-13 trait; otherwise, it does not have the C006-10-13 trait.

2. Identification method 2

(1) Using the genomic DNA of the offspring bred by C006-10-13 as a template, a primer pair consisting of primer 7 and primer 23 was used for PCR amplification to obtain a PCR amplification product.

The PCR amplification system was as follows: 2×MASTRE PCR MIX 10 μl, primer 7 (10 μM) 0.5 μl, primer 23 (10 μM) 0.5 μl, template DNA (50 ng/μl) 1 μl, ultrapure water 8 μl, total volume 20 μl.

The PCR reaction conditions are as follows: 94° C. for 5 min; 32 cycles of 94° C. for 30 s, 55° C. for 30 s, and 72° C. for 1 min; 72° C. for 5 min.

(2) Perform agarose gel electrophoresis on the PCR amplification product obtained in step (1), and then make the following judgment: if the PCR amplification product contains a DNA fragment of about 900bp, it means that the offspring bred by C006-10-13 contain C006- 10-13 amplicon, the C006-10-13 breeding offspring has the C006-10-13 trait; otherwise, it does not have the C006-10-13 trait.

(2) Analysis of resistance to mirid bugs and agronomic traits of C006-10-13 breeding offspring

According to the method of 1 in step 2 in Example 1, detect the mirid bug resistance and agronomic traits of the C006-10-13 breeding offspring with the C006-10-13 amplicon obtained in the above step (1) and upland cotton CCRI24 analyze.

The results of the analysis of agronomic traits are shown in Table 5. The results showed that compared with upland cotton CCRI24, the plant height, length of the first fruiting branch, number of fruiting branches, number of bolls and coat percentage of the offspring bred by C006-10-13 were all significantly increased.

Table 5. Comparison of agronomic traits between transgenic cotton C006-10-13 and upland cotton CCRI24

See Table 6 for the results of the identification of the resistance to mirid bugs. The results showed that compared with upland cotton CCRI24, the progeny of C006-10-13 had significantly improved resistance to mirid bugs, and the degree of leaf damage was also significantly reduced.

A method for identifying whether a plant sample is derived from transgenic cotton or its progeny, comprising the steps of: Detect whether the genomic DNA of the plant sample to be tested contains DNA fragment A; the DNA fragment A consists of an exogenous DNA fragment in the upstream flank fragment of the transgenic cotton, the exogenous DNA fragment and the exogenous DNA fragment in the The downstream flank segment composition of the transgenic cotton; If the genomic DNA of the plant sample to be tested contains the DNA fragment A, the plant sample to be tested is or is a candidate for the transgenic cotton or its progeny; If the genomic DNA of the plant sample to be tested does not contain the DNA fragment A, the plant sample to be tested is not or the candidate is not the transgenic cotton or its progeny; The nucleotide sequence of the upstream flanking sequence is shown in sequence 2 in the sequence listing; The nucleotide sequence of the downstream flanking sequence is shown in sequence 3 in the sequence listing; The nucleotide sequence of the exogenous DNA fragment is shown in sequence 1 in the sequence listing; The transgenic cotton is obtained by inserting an exogenous DNA fragment into the position 63328845-63329028 of chromosome D12 of the target cotton genome, and replacing the base sequence of 182 bp between positions 63328845-63329028 of chromosome D12; The mirid bug resistance, plant height, length of the first fruiting branch, number of fruiting branches, number of bolls and lint fraction of the transgenic cotton are all higher than those of the target cotton; the single boll weight of the transgenic cotton is lower than that of the target cotton . 2. The method according to claim 1, characterized in that: the method for detecting whether the genomic DNA of the plant sample to be tested contains DNA fragment A is direct sequencing. 3. A method for obtaining the cotton that the mirid bug resistance improves, the plant height increases, the length of the first fruiting branch increases, the number of fruiting branches increases, the number of bolls increases, the percentage of clothing increases and the weight of a single boll decreases, comprising the steps of: (1) obtaining the transgenic cotton described in claim 1; (2) Selfing or hybridizing the transgenic cotton to obtain breeding offspring, identifying the breeding offspring according to the method described in claim 1 or 2, to obtain the target plant. 4. The method according to claim 3, characterized in that: the deposit number of the transgenic cotton is CCTCC NO:P201822. 5. the application of method described in claim 1 in cotton breeding.
