Embodiment 1
[0028] Cloning of embodiment 1, GmST2
[0029] 1.1 Extraction of total RNA of Shengdou No. 9
[0030] (1) Put the plant material of Shengdou No. 9 into a mortar, and use liquid nitrogen to grind it into powder (directly used in the following experiments or frozen in a -80°C ultra-low temperature refrigerator for later use);
[0031] (2) After the liquid nitrogen volatilizes, immediately transfer 100-200mg of plant powder into a 1.5ml centrifuge tube, then quickly add 1ml of Trizol extract, vortex to fully dissolve the sample into the extract, and place it at room temperature for 5 minutes;
[0032] (3) 4°C, 12,000rpm, centrifuge for 10min, transfer 0.9ml of the supernatant to a new 1.5ml centrifuge tube, then add 0.2ml of chloroform, vigorously shake and mix for 15sec, and place at room temperature for 2-5min;
[0033] (4) 4°C, 12,000rpm, centrifuge for 10min, transfer 0.4ml of supernatant to a new 1.5ml centrifuge tube, add 0.4ml of isopropanol, turn up and down 15 times to...
Embodiment 2
[0138] Example 2, Functional Verification of Expressing the NAC Transcription Factor Gene GmST2 of Saint Bean No. 9 in Arabidopsis
[0139] 2.1 Transformation of Arabidopsis thaliana by flower infection method
[0140] (1) When Arabidopsis thaliana (Col-0 wild type) grows to 1 cm of bolting, the top is subtracted to induce the formation of lateral inflorescences;
[0141] (2) One day before transformation, take 1ml of activated Agrobacterium GV3101 containing the expression vector plasmid and add it to 40ml of YEP medium containing corresponding antibiotics and 50μg / ml rifampicin, and culture with shaking at 28°C until OD 600 About 1.0-1.2;
[0142] (3) room temperature, 4200rpm, centrifuge 10min, collect the thalli, resuspend the thalli with the liquid (5% sucrose, 0.05% Silwet L-77), make OD 600 about 0.8;
[0143] (4) Use a pipette to drop the Agrobacterium on the inflorescences for dipping, and after all the inflorescences are infected, put the Arabidopsis thaliana into...
Embodiment 3
[0182] Example 3, Functional Verification of Expressing Shengdou No. 9 NAC Transcription Factor Gene GmST2 in Soybean
[0183] 3.1 Transformation of Soybean by Vacuum Infiltration Assisted Transformation of Germinated Soybean Embryos
[0184] (1) Seed disinfection and pre-cultivation treatment
[0185] Soybean seeds were sterilized with 70% ethanol for 5 minutes, and then cleaned with 0.1% HgCl 2 Disinfect for 10 minutes, rinse with sterile water 5-6 times, and soak the seeds in sterile water for 12 hours at 25°C-28°C.
[0186] Soybeans whose embryos swelled and germinated after soaking were put into the pre-cultivation medium, and cultured in light at 28°C for 1 day, wherein the formula of the pre-culture medium was: MS+3.0mg / L 6-BA (6-benzylaminoadenine) +20g / L sucrose+7g / L agar, pH5.8.
[0187] (2) After the seed embryo swells and germinates, it is cut to expose or damage the germinated embryo part
[0188] When the whole pre-cultivated soybean embryo is enlarged and th...
