摘要:
旨在利用磁性纳米颗粒作为载体构建小球藻的新型转化方法，由于纳米载体技术已经被成功地应用于动、植物的遗传转化中，其主要优势是相对于传统转化技术更加便捷、高效。本研究首先利用磁性纳米颗粒吸附含有增强型绿色荧光蛋白基因（EGFP）的质粒载体pYBA1132，形成纳米颗粒-基因复合物，通过磁场作用对椭圆小球藻原生质体进行转化，进而观察EGFP基因在椭圆小球藻中的瞬时表达情况。结果表明，对椭圆小球藻细胞进行酶解处理并形成半原生质体/原生质体后，磁性纳米颗粒可以介导外源EGFP基因转入小球藻中，并能够进行瞬时表达，产生绿色荧光。
Abstract:
Using magnetic nanoparticles as carriers, a new transformation method of Chlorella ellipsoidea was constructed. Nanocarrier technology has been successfully applied to genetic transformation of animals and plants, which is more convenient and efficient than traditional transformation technologies. In this study, magnetic nanoparticles were used to absorb plasmid vector pYBA1132 containing enhanced green fluorescent protein gene (EGFP), and the nanoparticles-gene complexes were formed. In addition, the protoplasts of Chlorella ellipsoidea were transformed by magnetic force, and the transient expression of EGFP in Chlorella ellipsoidea was observed. After the formation of semi-protoplasts/protoplasts in Chlorella ellipsoidea cells by enzymolysis treatment, the magnetic nanoparticles mediated the transfer of exogenous EGFP gene into Chlorella ellipsoidea, and green fluorescence was detected after transient expression.
