The full-length cDNAs of rice and wheat S-adenosylmethionine decarboxylase gene were isolated and characterized. The rice SAMDC cDNA is 1560 bp in length, encoding a polypeptide of 398 amino acids, and the wheat SAMDC cDNA is 1351 bp in length, encoding a polypeptide of 392 amino acids. Both the rice and wheat SAMDC proteins contain the conserved proenzyme cleavage site and the PEST domains, which are commonly found in the SAMDC protein sequences of all eukaryotes.

Recombinant expression vector k14/c-myc-paav was constructed bearing the mouse c-Myc cDNA derived by the skin specific human keratin 14 promoter, then the linear vector was microinjected into the two pronucleus of the C57BL/6 fertilized eggs to produce transgenic mice.256 microinjected eggs were transferred, 6 of the foster mothers were pregnant and 44 adult mice were produced, two of them were positive transgenic mice confirmed by PCR and Southern blot analysis, transgenic rate was about 4%.

以CMV-PAAV载体为基础载体，以皮肤特异人K14（人角蛋白14）基因启动子替换原质粒中的CMV启动子后，在其多克隆位点区依次插入鼠c-Myc基因的cDNA序列和gfp基因的编码序列，构建了高效表达c-Myc基因的真核表达载体。通过双原核显微注射技术，将线性化的载体DNA注入到C57BL/6小鼠受精卵的两个原核中，然后将注射后状态良好的胚胎移植到代孕鼠的输卵管中，共移植了256枚受精卵，6只受体怀孕，最终获得44只成年小鼠。
