Example Embodiment
[0041] Example 1 Cultivation of transgenic tobacco with Mn-SOD gene, Cu / Zn-SOD gene or Fe / Mn-SOD gene
[0042] 1. Construction of transgene expression vector
[0043] 1. Acquisition of Mn-SOD gene, Cu / Zn-SOD gene and Fe / Mn-SOD gene
[0044] The present invention clones three SOD genes from a strain of Geobacillus sp. The primers used in PCR are: the upstream primer C of Mn-SOD gene GAGCTC ATGCCATTTGAATTGCCAGC, introduce restriction site SacI, downstream primer C GGATCC TTACTTCGCTTTCGCTTCGC, introduce restriction site BamHI; the upstream primer C of Cu / Zn-SOD gene GAGCTC ATGCGAAAAACGTACGGTGTG, introduce restriction site SacI, downstream primer C GGATCC TCACGACGACTTGATTTCCC, introduce restriction site BamH I; the upstream primer C of Fe / Mn-SOD gene GGATCC ATGCGTGGGGCAAGCAC, introduce restriction site BamHI, downstream primer C TCTAGA TTAAAACGGCTGCCAACG, introduce restriction site XbaI. The PCR amplification system is 50μL, and 1μL genomic DNA is used as the template. The amplif...
