Definitions
- the present invention provides a method for producing a chimeric transgenic plant having a transgene only in some cells.
- chimeras An individual consisting of a plurality of genetically different cell groups is called a chimera.
- Plant chimeras are divided into peripheral chimeras, partial chimeras and segmented chimeras based on their structure.
- segmental chimeras that can be created by accidental or somatic mutation by radiation or chromosome doubling by drug treatment (sectorial chimera) ) Is a non-structural chimera that originates from the stacked structure of plants, and is caused by the proliferation of mutant cells that are non-structurally mixed at the growth point. That is, one tissue layer itself is a chimera and often appears as a different colored stripe on organs such as flowers, leaves, and stems. Sorted chimeras are usually unstable and often disappear, but rarely develop into peripheral chimeras.
- Periclinal chimera is a structural chimera that originates from the tissue layer structure of a plant and has developed a segmented chimera, and one cell layer has been completely replaced with mutant cells. In the case of a peripheral chimera, one tissue layer itself is uniform and not a chimera. Peripheral chimeras are stable and are said to disappear less frequently.
- Plant cell tissue is basically composed of three cell layers, and has a tissue layer structure of the first layer (L1), second layer (L2), and third layer (L3) from the outside. L 1 and L 2 are generated from the two layers of the growth point (t un i ca), and L 3 is generated from the inner body (corpus).
- the epidermis is all produced from the L1 layer, which is related to the germline.
- Peripheral chimeras with different properties for each of these cell layers are important for horticulture and have high industrial value, but accidentally or artificially induce mutations such as irradiation and drug treatment The probability of obtaining a peripheral chimera is also very low by this means.
- a foreign gene When a foreign gene is introduced into a plant, it is not easy to artificially create a chimeric plant having a gene introduced into only some cells. So far, there has been an example in which a chimera plant having a transgene only in a germ cell or L2 cell layer was created by introducing a gene into an immature corn embryo by a method using a particle gun (see Table 10). No. 503374). However, if the gene is introduced through agrobacterium, it is more difficult to create a chimeric plant. In the method of introducing a gene via agrobacterium, a single cell into which the gene has been introduced is selected using a trait such as drug resistance due to the expression of the marker gene as an indicator, and the single cell is selected. One individual transformant plant is obtained from the transgenic cell.
- genetically modified plants consist of genetically single cells and have transgenes in all cells. Even if a plant (chimeric plant) that has a foreign gene only in some cells is obtained, it is a coincidence, and with the current technology, a gene is only present in a specific part of the plant. It is very difficult to control it to be introduced. Even if it is obtained by chance, as described above, the probability of becoming a peripheral chimera having a gene only in a part of the cell layer is considered to be extremely low.
- transgenic cells only a part of them
- a chimeric cell mass or a chimeric plant that has been introduced into the gene may appear, but in this case, the chimera or the single tissue layer itself is chimera throughout the entire cell layer.
- Foreign genes are introduced only into the layer, and the cell layer itself is not uniform.
- a peripheral chimera body can be produced by using a vector containing a gene and a desorption factor (JP 2002-3 15460). is there.
- transgenic plants In transgenic plants, transgenes incorporated into chromosomes are stably transmitted to their progeny according to Mendel's law. By using these transgenic plants as mating parents, new varieties can be created using the traits derived from the introduced gene.
- genetically modified plants there are concerns about the impact on the ecosystem (environment) (such as the spread of transgenes into nature).
- Technologies to prevent gene spread from genetically modified plants to non-transformants and wild plants include: (1) use of maternal inheritance, (2) use of male sterility, (3) use of sterile seeds, etc. It has been known.
- the use of maternal inheritance is a method of preventing gene spread by pollen by introducing a foreign gene into the chloroplast genome that is not transmitted to pollen cells.
- male sterility refers to a method that inhibits pollen formation or prevents pollen from having fertility, thereby allowing genetic isolation. For example, there is a method in which pollen formation is inhibited by using a promoter that is expressed specifically in the male reproductive organs to make a harmful gene product tissue-specific.
- the use of sterile seeds is a method to prevent both crossing and spreading of seeds by directly inhibiting the seed formation of genetically modified plants, making self-seeding impossible. Etc. This is the case.
- transgenic plant that does not have a transgene in germ cells
- This also reduces the burden on procedures for cultivating genetically modified plants for those who cultivate genetically modified plants outdoors or for industrial use.
- such procedures include biodiversity impact assessments based on the “Law Concerning the Ensuring Biodiversity through Regulations on the Use of Genetically Modified Organisms, etc. (Karuyu Henna Law)”. In other countries, there are evaluations based on similar laws.

- transgenes were detected in the petal, leaf, and stem genomes of this recombinant plant, but these transgenes were not detected in the root and pollen genomes.
- Table 3 and Fig. 1 show the results.
- petals, leaves and stem epidermis, sepals, stamens, pistils are derived from the L1 and L2 layers
- pollen and egg cells are derived from the L2 layer
- leaves and stem internal tissues are derived from the L3 layer.
- roots are derived from the L3 layer.
- Example 3 Recombinant No. 24 (WKS82 / 130-9-1; hereinafter referred to as recombinant) pollen was attached. After that, we pouched again to prevent other pollen from adhering, and investigated the presence or absence of seed formation.
- the pollen used was fresh pollen collected from the cocoons that had been cleaved the next day after collecting the pods before cleavage and leaving them at room temperature for 1 day in a dessert overnight containing silica gel.
- Grandi Flora four seasons rose cultivar Queen Elizabeth ”and Floribunda four-season rose cultivar“ Gold Baniichi ” were used.
- Genomic MA is extracted from the re-collected seeds using Nucleon PHYTOPURE for PLANT DNA EXTRACTION KIT (Amersham Biosciences), further amplified with the REPLI-g Kit (QIAGEN), and then introduced into the introduced gene (pansy by PCR).
- Tables 5 and 6 show the results of detection of the F3 ′ 5 ′ H gene). There was almost no difference in the fruiting rate between the host and the recombinant.
- the pollen used was fresh pollen collected from the cocoons that had been cleaved the next day after collecting the pods before cleavage and leaving them at room temperature for 1 day in a desiccant with silica gel.
- the KSN gene is produced by inserting a transposon of about 9 kb into the ksn gene (which maintains the shoot apex) that blooms in a single season, which suppresses the expression of the gene and forms flower buds at the shoot apex. because suppression is released, 1 flower bud formation is promoted, it has been reported that a perpetual property).
- Horticultural species have the KSN gene in homology.
- wild species that bloom in season have a homologous ksn gene. Therefore, in wild species (temporarily blooming), the KSN gene is considered to be detected only when crossed with horticultural species.
- Genomic DNA is extracted from the re-collected seeds using Nucleon PHYTOPURE for PLANT DNA EXTRACTION KIT (Amersham Biosciences), further amplified with the REPLI-g Kit (QIAGEN), and then host or recombinant by PCR.
- Nucleon PHYTOPURE for PLANT DNA EXTRACTION KIT Amersham Biosciences
- REPLI-g Kit QIAGEN
- the results are shown in Table 7 and Table 8.
- the fruit set was extremely low whether the host or the recombinant plant was the pollen parent.
- the obtained seedlings were analyzed by the PCR method. However, although a cross between the host or the recombinant and the wild species was observed, no transgene derived from the recombinant was detected. In addition, the seeds that have not germinated have been collected again and observed for seed enrichment. As a result, most of them were “Shi” (those without seed contents), and very few individuals were able to confirm normal embryos. These were also analyzed by PCR in the same manner, but no transgene derived from the recombinant was detected, although hybridization between the host or recombinant and wild species was observed. From this, it was considered that the transgene was not transmitted to the progeny because the transgene was not contained in the recombinant pollen cells.
- DIG-labeled probes (BP40, TAT, and NPTIK gene antisense and sense probes) were dissolved in a hybridization solution and reacted on a dried slide glass. After hybridization, the slide glass was washed and DIG was detected. As shown in the photograph in Fig. 2, the transgene is expressed only in the cells in the L1 layer and is not expressed in the cells in the L2 and L3 layers. This means that the transgene is present only in the L1 layer and not in the U or U layer, and therefore there is no transgene in the germ cells (pollen cells or ovule cells) generated from the L2 layer. Proven.
- a carnation was created in which the transgene was present only in the L1 layer.
- the recombinant carnation was prepared as follows by gene transfer using agrobacterium. Plasmid p CGP2442 (Appli cation No. US60 / 988, 293, filed on Nov. 15, 2007) is located in its TD NA region and is under control of salvia under the control of the goldfish sour chalcone synthase gene.
- the causal flower mosaic virus 35S promoted tobacco tobacco lactate synthesis gene SURBc DNA is included. This was introduced into agro-pacteria by the method described in Japanese Patent Application Special Publication No. 1-5051 16, and further introduced into the force-neutral variety Cortina Chanel. Delphidinidine, which is not contained in natural carnations, was detected in the petals of the resulting recombinant carnation. This indicates that the transgene is functional in at least petal epithelial cells.
- system 19907 was analyzed in detail.
- chromosome DNA was extracted from strain 19907 and analyzed by the Southern hybridization method using the above gene on PCGP2442 T-DNA as a probe, the transgene was inserted into the chromosome. was confirmed.
- Tissue cultures were made by planting 1990 1990 and 26898 shouts in hormone free MS solid medium containing 5 / z g / L Glean. When we observed the presence or absence of rooting in 4-5 weeks, line 26898 was rooted, but line 19907 was not rooted.
- Chromosomal DNA was extracted from the leaves and roots of line 19907 using the DNeasy Plant Mini Kit (QIAGEN). Synthetic primers (# 960 5 '-ATT TCC GCC TCA TTA GAA GG-3', # 1468 5, -GCC TCA TGT TTC CAT TTG TGC-3 ' ) was used for PCR. The reaction was performed using Hot Star TaQ with a reaction volume of 25 1 and a 95 ° reaction for 15 minutes, then a 96 ° reaction for 1 minute, a 52 ° reaction for 30 seconds, and a 72 ° reaction for 2 minutes. One cycle of 35 cycles was performed, and another 72-degree reaction was performed for 7 minutes.

- the transformation of torenia was performed by a known method (Mol. Breeding 6, 239-246 (2000)).
- the SWB flower color is blue, but for the purpose of this experiment, the torenia varieties used are not limited to SWB. Forty independent transformed trainer lines TAG were obtained.
- the gene involved in the synthesis of flavonoids was introduced as an exogenous gene using Trenya as a flowering plant.
- the gene cassette involved in aurone synthesis and the anthocyanin synthesis system can be obtained using the same agrobacterium as described above, using the trenia cultivar sama wavuru 1 as the host plant.
- RNAi A construct with a cassette (PSFL307 or PSFL308) was introduced.
- PSFL307 or PSFL308 was introduced.
- the flower color changed from blue to yellow.
- the Arabidopsis thaliana PHR1 gene (Genes & Development 15: 2122-2133 (2001)) expressed under phosphate starvation conditions is subcloned into a vector of pCR2.1. did.
- PSPB2311A was obtained.
- PSPB 1892 was cleaved with EcoRI and the blunted fragment was inserted into pS PB2311A to obtain PSPB2314.
- agrobacterium strain: AglO
- pS PB 1898 agrobacterium having this PSPB1898 was transformed.
- Baco, Bapena, and Nielenbergia Tobacco, verbena, and 21-bell gear were transformed based on known methods (Science 227, 1229, 1985; Plant Cell Rep. 21, 459, 2003; Plant Biotech. 23, 19, 2006), respectively.
- the gene introduction of the obtained plant bodies was confirmed by PCR using DNA extracted from the leaves of each plant body and using the PHR1 gene as a template.
- Impatiens or begonias were used as flowering plants, and transcription factor genes were introduced as foreign genes.
- Impatiens walleriana was basically transformed according to US Patent 6, 121, 511 using the varieties glittered red (Sakata evening) and tempo pink (evening seedling seedling).
- the shoot apex, nodes, petiole, and leaf pieces cut out from Vitro seedlings were pre-cultured in pre-culture liquid medium (MS medium supplemented with lmg / L TD Z) for 5 days, and then pre-cultured solid medium (0.05 mg / L NAA, 6 mg / L Zeatin) And MS medium supplemented with 0.3% gellan gum) for 48 hours.
- infection with agropacterium introduced with PSPB2314 was carried out on selective medium (0.05mg / L NAA, 6mg / L Zeatin, lOOmg / L Kanamyc in, 500mg / L Carbenic i 11 in, lOOmg / L-cefotaxime, MS medium supplemented with 0.3% gellan gum, was cultured for 4-8 weeks to obtain shoots (Table 9).
- selective medium 0.05mg / L NAA, 6mg / L Zeatin, lOOmg / L Kanamyc in, 500mg / L Carbenic i 11 in, lOOmg / L-cefotaxime, MS medium supplemented with 0.3% gellan gum
- the shoots formed in the meantime grew to a diameter of 5 mm or more, and the surrounding tissue was scraped off and transferred to selective medium 4 (150 mg / L Kanamycin, 500 mg / L Timentin, 0.4% agar-added MS medium).
- selective medium 4 150 mg / L Kanamycin, 500 mg / L Timentin, 0.4% agar-added MS medium.
- the cells were transferred to a rooting medium (100 mg / L Kana mycin, 500 mg / L Timentin, MS medium supplemented with 0.4% agar) to obtain a rooting medium (Table 10).

- any gene that functions in L1 cells after introduction can be introduced into these floret plants using the same method. It is done.
- the technology of the present invention can introduce a foreign gene using agrobacterium. Since these plants are also adaptable to floret plants, the floret plant of the present invention, that is, a floret in which the transgene is present only in some cells of the transformant plant and is not present in other cells. It is possible to create plants.
- the transformant plant produced by the method disclosed by the present invention is a chimeric plant having no transgene in the L2 cell layer containing germ cells and the like, but having the transgene only in the cells of the L1 layer. . Since such a transformant does not have a transgene in the germ cell, it is possible to prevent the possibility that the transgenic plant can be freely used as a mating parent by an unauthorized third party.
