Embodiment 1
[0044] Example 1 Obtaining of KUP3 gene
[0045] Get 0.5g of fresh tobacco leaves, use the Trizol method to extract the total RNA of tobacco cells, then use the cDNA synthesis kit of TaKaRa company to synthesize cDNA, and further use the Primer5.0 software to design and obtain primers through artificial optimization. The primers include forward primers and a reverse primer, the nucleotide sequence of the forward primer is: 5'-ATGGATATCGACTACGGGAA-3'; the nucleotide sequence of the reverse primer is 5'-TTAAACAATGTAGACCATCC-3', using the synthetic cDNA as a template , for PCR amplification.
[0046] The PCR amplification system is a 20 μL system, including: Premix ExTaq 10 μL, 10 μM forward primer 0.5 μL, 10 μM reverse primer 0.5 μL, tobacco cell cDNA 1 μL, ddH 2 O 8 μL.
[0047] The PCR amplification reaction program was: pre-denaturation at 95°C for 5 min; denaturation at 95°C for 30 s, annealing at 55°C for 30 s, extension at 72°C for 2 min, and 35 cycles.

Embodiment 2
[0049] Example 2 The role of KUP3 gene in promoting the absorption and transport of potassium ions
[0050] The T-vector and the expression vector P416 connected with the KUP3 gene described in Example 1 were subjected to double enzyme digestion (restriction sites: SmaI and XhoI), and the target gene and expression vector P416 were recovered, and then ligated with ligase , transfer the ligated recombinant yeast expression vector into Escherichia coli DH5α competent cells, carry out PCR amplification and enzyme digestion on the transformed Escherichia coli single colony to verify whether the construction is successful, and transfer the successfully constructed recombinant yeast expression vector into into R5421.
[0051] The specific steps are as follows: Streak the preserved R5421 yeast on the solid medium YPDA with an inoculation loop, culture at 28°C for 12 hours; pick a single colony of R5421 yeast in the Ep tube, add 1mL of YPDA culture solution and vortex; Transfer all t...
