Description

Technical Field

[0001] The invention belongs to the field of biotechnology, and in particular relates to sorghum SbMS1 protein and a coding gene and application thereof. Background Art

[0002] Hybrid vigor is a common phenomenon in the biological world. It refers to the phenomenon that the hybrids produced by the crossbreeding of two parents with different genotypes exceed their parents in growth potential, vitality, fecundity, adaptability, yield, quality and other traits. The use of hybrid vigor is also an important way to increase crop yields. Among them, the cloning of male sterility genes and the cultivation of male sterile lines are the premise and basis for the effective use of hybrid vigor in self-pollinating crops. With rice as a representative, there are two main ways of utilization: "cytoplasmic-nuclear interaction three-line" and "photothermal-sensitive sterile two-line". In sorghum, the use of hybrid vigor is realized by using cytoplasmic male sterile lines. However, "cytoplasmic-nuclear interaction three-line" and "photothermal-sensitive sterile two-line" have their own shortcomings. For example, the cultivation of cytoplasmic male sterile lines requires multiple generations of backcrossing, which is time-consuming and labor-intensive; the production of seeds requires the matching of sterile lines, maintenance lines, and restorer lines, and the seed production process is cumbersome; the genetic resources of the restorer line are limited and require special cultivation; the fertility of the photothermal-sensitive male sterile line is unstable and easily affected by environmental changes, etc.

[0003] High male sterility in plants refers to the phenomenon that the female gametophyte of the plant develops normally, while most of the male gametophytes develop abnormally and usually can only produce a small amount of functional pollen. Plants can be maintained by self-pollination with a small amount of normal pollen, especially some crops with high reproduction coefficients such as rice, wheat, sorghum, rapeseed, millet, pearl millet, etc. Using this highly male sterile material to cultivate a sterile line, combined with materials with dominant herbicide resistance traits as a restorer line, hybrids can be prepared, greatly broadening the genetic basis for the use of hybrid vigor, simplifying the seed production process, and the fertility of the sterile line is relatively stable, which has obvious advantages over the traditional "cytoplasmic-nuclear interaction three-line" and "photothermal-sensitive sterile two-line". Summary of the invention

[0004] The first object of the present invention is to provide a new use of SbMS1 protein.

[0005] The present invention provides the use of SbMS1 protein in regulating plant male fertility:

[0031] The nucleic acid molecule may be DNA, such as cDNA, genomic DNA or recombinant DNA; the nucleic acid molecule may also be RNA, such as mRNA or hnRNA.

[0032] A person skilled in the art can easily mutate the nucleotide sequence encoding the protein SbMS1 of the present invention by using known methods, such as directed evolution and point mutation. Those artificially modified nucleotides having 75% or higher identity with the nucleotide sequence encoding the protein SbMS1 are derived from the nucleotide sequence of the present invention and are equivalent to the sequence of the present invention as long as they encode the protein SbMS1 and have the same function.

[0033] The term "identity" as used herein refers to sequence similarity to a natural nucleic acid sequence. "Identity" includes nucleotide sequences that have 75% or more, or 85% or more, or 90% or more, or 95% or more identity to the nucleotide sequence of the protein composed of the amino acid sequence shown in the coding sequence 3 of the present invention. Identity can be evaluated by the naked eye or by computer software. Using computer software, the identity between two or more sequences can be expressed as a percentage (%), which can be used to evaluate the identity between related sequences.

[0034] The aforementioned 75% or more identity may be 80%, 85%, 90% or 95% or more identity.

[0035] In the above application, the stringent conditions are hybridization and washing at 68°C in a 2×SSC, 0.1% SDS solution for 5 min each time, and hybridization and washing at 68°C in a 0.5×SSC, 0.1% SDS solution for 15 min each time; or hybridization and washing at 65°C in a 0.1×SSPE (or 0.1×SSC), 0.1% SDS solution.

[0036] In the above application, the expression cassette (SbMS1 gene expression cassette) containing a nucleic acid molecule encoding protein SbMS1 described in A2) refers to a DNA capable of expressing protein SbMS1 in a host cell, and the DNA may include not only a promoter for initiating transcription of SbMS1, but also a terminator for terminating transcription of SbMS1. Further, the expression cassette may also include an enhancer sequence. Promoters that can be used in the present invention include, but are not limited to, constitutive promoters; tissue, organ and development-specific promoters and inducible promoters. Suitable transcription terminators include, but are not limited to, Agrobacterium nopaline synthase terminator (NOS terminator), cauliflower mosaic virus CaMV 35S terminator, tml terminator, pea rbcS E9 terminator, and nopaline and octopine synthase terminators.

[0037] The recombinant vector containing the SbMS1 gene expression cassette can be constructed with an existing expression vector.

The polyadenylic acid signal can guide polyadenylic acid to be added to the 3' end of the mRNA precursor, such as the Agrobacterium crown gall induction (Ti) plasmid gene (such as the nopaline synthase gene Nos), the non-translated region transcribed at the 3' end of the plant gene (such as the soybean storage protein gene) all have similar functions. When using the gene construction plant expression vector of the present invention, enhancers can also be used, including translation enhancers or transcription enhancers. These enhancer regions can be ATG start codons or adjacent region start codons, etc., but must be identical to the reading frame of the coding sequence to ensure the correct translation of the entire sequence. The source of the translation control signal and the start codon is extensive and can be natural or synthetic. The translation initiation region can come from a transcription initiation region or a structural gene. In order to facilitate the identification and screening of transgenic plant cells or plants, the plant expression vector used can be processed, such as adding genes that can be expressed in plants and encode enzymes or luminescent compounds that can produce color changes (GUS gene, luciferase gene, etc.), antibiotic marker genes (such as nptII gene that confers resistance to kanamycin and related antibiotics, bar gene that confers resistance to the herbicide phosphinothricin, hph gene that confers resistance to the antibiotic hygromycin, dhfr gene that confers resistance to methotrexate, EPSPS gene that confers resistance to glyphosate) or chemical resistance marker genes (such as herbicide resistance genes), mannose-6-phosphate isomerase gene that provides the ability to metabolize mannose. Considering the safety of transgenic plants, no selective marker gene can be added, and transformed plants can be directly screened by adversity.

[0038] In the above applications, the vector may be a plasmid, a cosmid, a phage or a viral vector.

[0039] In the above applications, the microorganism may be yeast, bacteria, algae or fungi, such as Agrobacterium.

[0044] 1) Regulating plant male fertility;

[0045] 2) Cultivate male-sterile transgenic plants.

[0046] In the above application, the regulation of plant male fertility is to make the plant male sterile, which is manifested as: when the SbMS1 protein encoding nucleic acid in the plant is knocked out, the plant is male sterile, and further manifested as: when the SbMS1 protein encoding nucleic acid in the plant is knocked out, the pollen activity and / or fruit setting rate of the plant is significantly reduced.

[0047] The fourth object of the present invention is to provide a method for cultivating male sterile transgenic plants.

[0049] In the above method, the sequence of the SbMS1 protein encoding nucleic acid is the DNA molecule shown in Sequence 1 or Sequence 2.

[0050] Furthermore, the transgenic plant is male sterile, which is manifested in that the pollen activity of the transgenic plant is lower than that of the recipient plant and / or the fruit setting rate of the transgenic plant is lower than that of the recipient plant.

[0051] Furthermore, the substance for knocking out the nucleic acid encoding the SbMS1 protein in the recipient plant is a CRISPR / Cas9 system. The target sequence of the sgRNA in the CRISPR / Cas9 system is specifically a DNA molecule shown in Sequence 4.

[0065] Example 1: Application of SbMS1 protein in regulating plant fertility

[0066] 1. Obtaining SbMS1 knockout sorghum

[0067] 1. Design of knockout targets

[0068] According to the SbMS1 gene sequence, the SbMS1 gene knockout target sequence was designed using the plant CRISPR / Cas9 online target design website CRISPR-P 2.0 (http: / / crispr.hzau.edu.cn / CRISPR2 / ). The final screened SbMS1 gene knockout target sequence is as follows: 5'-CCGCACGTAGGGCGAATCCA-3' (sequence 4).

[0069] 2. Obtaining fragments containing target sequences for infusion connection

[0070] Add 5 μl of CRISPR (Sobic) upstream primer 5'-AGATGATCCGTGGCACCGCACGTAGGGCGAATCCAGTTTTAGAGCTATGC-3' and downstream primer 5'-GCATAGCTCTAAAACTGGATTCGCCCTACGTGCGGTGCCACGGATCATCT-3' to 10 μl of the system, incubate at 94°C for 10 min, anneal to 15°C at 0.1°C / s, and maintain at 15°C for 10 min to complete annealing and obtain a DNA fragment containing the target sequence for infusion connection.

[0071] 3. Construction of SbMS1 knockout vector

[0072] The PCas9 vector was digested with restriction endonuclease AarⅠ (Cat no.ER1581, ThermoFisherScientific, United States) at 37°C for 5 h to obtain a PCas9 linear vector. Then the DNA fragment 5'-AGATGATCCGTGGCACCGCACGTAGGGCGAATCCAGTTTTAGAGCTATGC-3' obtained in step 2 was ligated into the PCas9 linear vector using In-Fusion HD Cloning Kits (Cat no.639648, Takara, Japan), transformed into Escherichia coli competent cells Trans-T1 (Cat no.CD501, TransGen Biotech, China) and coated on solid LB medium containing spectinomycin Spec, and a single clone was picked and sequenced using primers 5'-CCCTTCACCGTCAGATGCTACT-3' and 5'-TGGATAATGTGCAAGGGATCTTT-3' (the target product sequence size was 1090 bp).

[0073] The nucleotide sequence of the PCas9 vector is shown in Sequence 5 in the sequence table, wherein positions 1611-1863 of Sequence 5 are nopaline synthase terminator, positions 1992-2789 are aminoglycoside phosphotransferase coding gene sequences, positions 2882-3061 are nopaline synthase promoter sequences, positions 3445-7545 are Cas9 (Csn1) endonuclease coding gene sequences of the type II CRISPR / Cas system of Streptococcus pyogenes, positions 7546-7566 are nuclear localization signal sequences, positions 7640-9632 are maize ubiquitin promoter sequences, positions 9707-10087 are rice snRNA U3 promoter sequences, and positions 10923-11013 are small guide RNA (sgRNA) coding gene sequences.

[0074] The sequencing results showed that the SbMS1 gene knockout vector was obtained by inserting the target sequence 5'-CCGCACGTAGGGCGAATCCA-3' between positions 10087 and 10923 of the PCas9 vector and keeping other sequences unchanged.

[0075] 4. Acquisition and identification of knockout sorghum

[0076] The SbMS1 gene knockout vector constructed in step 3 was introduced into Agrobacterium EHA105 to obtain recombinant bacteria; Agrobacterium-mediated genetic transformation was used to transform sorghum Tx430 immature embryo callus to obtain T 0 The primers 5'-GTGGAGCCCTGCTGCTG-3' and 5'-AAGGGCAGGCTACGACTA-3' (target product sequence size 315 bp) were used to generate transgenic plants. 0 DNA testing of transgenic plants was performed to determine the editing method of transgenic plants and obtain T 1 Generation seeds, sowed in a greenhouse, T 1 The transgenic plants of the first generation were tested for DNA again and the SbMS1 gene was amplified and sequenced using the primers in Table 1 to detect whether the editing method was stably inherited and the pure heterozygosity of the plant editing site. Finally, highly male-sterile plants were obtained. After sequencing, it was found that all of them were homozygous edited plants, and they were named sbms1#8, sbms1#11, and sbms1#20 respectively.

[0079] Compared with the wild-type sorghum Tx430 genomic DNA, the only difference of sbms1#8 is that a base A is inserted in the gene sequence encoding the SbMS1 protein shown in Sequence 1. The insertion position of the base A is between positions 259 and 260 in Sequence 1 ( Figure 1 ), which causes frameshift and premature termination, and loss of SbMS1 protein function. The SbMS1 genome sequence alignment diagram of the wild-type sorghum variety Tx430 and the gene-edited homozygous line sbms1#8 is shown in Figure 2. Figure 2 shown.

[0080] Compared with the wild-type sorghum Tx430 genomic DNA, the only difference of sbms1#11 is that there is a 3bp base deletion in the gene sequence encoding the SbMS1 protein shown in Sequence 1. The deleted bases are located at positions 260-262 (ATT) of Sequence 1, resulting in the change of Asp (D) at position 88 to Ala (A) and the deletion of Ser (S) at position 89 in the amino acid sequence of the SbMS1 protein shown in Sequence 3.

[0081] Compared with the wild-type sorghum Tx430 genomic DNA, the only difference of sbms1#20 is that there is a 25bp base deletion in the gene sequence encoding the SbMS1 protein shown in Sequence 1. The deleted bases are located at positions 238-262 of Sequence 1, resulting in frame shift and premature termination, and the SbMS1 protein function is lost.

[0082] 2. Fertility analysis of SbMS1 knockout sorghum

[0083] 1. Observation of plant and ear morphology

[0084] The wild-type sorghum variety Tx430 and the gene-edited homozygous line sbms1#8 at the flowering stage were used for plant morphological observation, and the wild-type sorghum variety Tx430 and the gene-edited homozygous line sbms1#8 at the mature stage were used for panicle phenotype observation.

[0085] Schematic diagram of plant morphological observation of wild-type sorghum variety Tx430 and gene-edited homozygous line sbms1#8 Figure 3 The results showed that there was no significant difference in plant height between the gene-edited homozygous line sbms1#8 and the wild-type sorghum variety Tx430. Figure 4 As shown, the results showed that the wild-type sorghum variety Tx430 had normal fruiting, while the gene-edited homozygous strain sbms1#8 had a serious impact on fruiting and only produced a small number of seeds, indicating that the SbMS1 mutation seriously affected sorghum fruiting.

[0086] 2. Pollen I 2-IK staining

[0087] Place the anthers of wild-type sorghum variety Tx430 and gene-edited homozygous strain sbms1#8 on a glass slide, add 1 drop of distilled water, crush the anthers thoroughly with tweezers to release pollen grains, and then add 1-2 drops of I 2 -KI solution, cover with a coverslip, and observe under a low-power microscope. Those stained black are active pollen grains containing starch, and those stained yellow-brown are poorly developed pollen grains.

[0088] The results are as follows Figure 5 As shown, pollen from wild-type sorghum variety Tx430 and gene-edited homozygous line sbms1#8 were subjected to I 2 -IK staining revealed that pollen from the wild-type sorghum variety Tx430 could be colored normally ( Figure 5 Left), while most pollen of the gene-edited homozygous strain sbms1#8 cannot be colored normally ( Figure 5 Right). The pollen activity of the gene-edited homozygous line sbms1#8 was significantly lower than that of the wild-type sorghum variety Tx430 ( Figure 6 Left).

[0089] 3. Fruit setting rate

[0090] The ears of the wild-type sorghum variety Tx430 and the gene-edited homozygous line sbms1#8 at maturity were taken, and the number of florets and the number of fruits on the five primary branches of each ear were randomly counted. The fruit setting rate was calculated according to the formula "fruit setting rate = (number of fruits / number of florets) * 100%". The fruit setting rates of at least 5 plants were counted for the wild-type sorghum variety Tx430 and the gene-edited homozygous line sbms1#8, respectively.

[0091] The results are as follows Figure 6 The results showed that the wild-type sorghum variety Tx430 could bear fruit normally, while the fruit-bearing rate of the gene-edited homozygous line sbms1#8 was significantly reduced ( Figure 6 Right). This indicates that the gene-edited homozygous line sbms1#8 exhibits a partial male sterility phenotype, that is, SbMS1 mutation can lead to high male sterility in sorghum, and SbMS1 has the function of regulating plant male fertility.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
