以构建水稻osvdac3基因超表达载体并获得超表达的转基因水稻植株为目标,通过PCR扩增将水稻0swdac3基因的全长片段克隆到植物表达载体,构建CaMV35S::osvdac3::rfp植物超表达载体。并以水稻YTB品种作为其遗传转化的受体,通过农杆菌介导的愈伤组织侵染法进行水稻遗传转化。结果表明,利用该方法成功构建了水稻osvdac3基因超表达载体.在此基础上获得了多个osvdac3基因超表达的水稻植株,并使用RT—PCR技术分析了阳性植株中osvdac3基因的表达水平。该研究结果为进一步研究水稻osvdac3基因蛋白的功能奠定了基础。
The goal of the research was to construct the over-expression vector of osvdac3 and to obtain the transgenic plants. Cloning the osvdac3 full-length gene into the plant expression vector by PCR,the over-expression vector was constructed with CaMV35S :: osvdac3 :: rfp. Through Agrobacterium-mediated approach, the recombinant plasmid was transformed into the rice YTB's callus. The results showed that the over-expression vector of CaMV35S :: osvdac3 :: rfp was constructed successfully and some transgenic plants were obtained. Meanwhile, the expression level of osvdac3 in the transgenic plants was confirmed by RT-PCR. The results laid the basic foundation for further function research of osvdac3.
