Embodiment 1
[0030] Cloning of the GbMYB4 gene
[0031] (1) Based on Ginkgo biloba genome and Ginkgo transcriptome data, a MYB gene was screened and named GbMYB4 through sequence alignment and evolution analysis. The ORF primers of GbMYB4 were artificially designed using Primer Premier 5.0 software. Among them, the GbMYB4 ORF forward primer (ORF F primer) is seq id no.3: 5'-atgggtcggtctccttgctg-3', and the gbmyb4 orf reverse primer (orf r primer) is seq id no.4: 5'-tacccgcagttgcctgtaat-3 '.
[0032] (2) Using the high-fidelity enzyme PrimeSTAR Max (Takara, Japan) for PCR amplification, the PCR system is as follows:
[0033]
[0034] Gently mix the above mixture, centrifuge briefly at low speed and place it in an ordinary PCR reaction instrument, set the following program:
[0035]
[0036] Gel running: Take out the gene amplification product in the PCR instrument, use the electrophoresis instrument to spot an appropriate amount of the product on a 1% agarose gel for detection, tak...
Embodiment 2
[0056] Construction of GbMYB4 Gene Plant Expression Vector
[0057] (1) This experiment uses TaKaRa QuickCut restriction enzyme (TaKaRa, Japan) to pCAMBIA2300-35S-OCS vector ( figure 2 ) (Genome-wide identification and analysis of the growth-regulatingfactor family in Chinese cabbage (Brassica rapa L.ssp.pekinensis), Wang et al.BMC Genomics 2014, 15:807) and the ORF sequence of GbMYB4 were subjected to enzyme digestion experiments, and the specific reactions The system is as follows:
[0058]
[0059] After the solutions in the system were mixed, they were centrifuged instantaneously, incubated in a 37°C water bath for 30 minutes, and then the enzyme digestion reaction was completed. The enzyme-cut bands were observed by agarose gel electrophoresis, and then the target gene and carrier fragments were cut and recovered for subsequent use. The carrier ligation reaction.
[0060] (2) Referring to the operation manual of TaKaRa T4 DNA Ligase (TaKaRa, Japan), connect the expr...

[0067] Genetic transformation of the GbMYB4 gene
[0068] 1. Genetic transformation of Arabidopsis
[0069] (1) Planting wild-type Arabidopsis thaliana in a normal growth environment;
[0070] (2) Select the Arabidopsis plants that have just bloomed for about four weeks in the soil, and cut off the flowers that have bloomed and the existing siliques with scissors for Agrobacterium transformation;
[0071] (3) Inoculate the Agrobacterium containing the 35S::GbMYB4 carrier obtained in Example 2 into LB liquid medium with Kana and Rif antibiotics, put it in a shaker at 28°C, and culture it overnight for 18-24h, until OD 600 =1.0-1.5;
[0072] (4) Put the bacterial solution that meets the requirements into a centrifuge tube, centrifuge at 4°C, 6000rpm, for 10min, and remove the supernatant;
[0073] (5) Add 50 mL of Arabidopsis transformation solution (5% sucrose+0.02% Silwet L-77) to the precipitate in step (4), and resuspend the precipitate;
[0074] (6) Remove the supernata...
