摘要
为验证单壁碳纳米管(SWNT)介导的新型的植物遗传转化方法的有效性,利用羧基化的单壁碳纳米管(COOH-SWNT)为原材料,构建了聚乙烯亚胺(PEI)修饰的羧基化单壁碳纳米管复合物(PEI-SWNT),探索验证PEI-SWNT复合物对外源基因的结合比例以及保护作用,使用PEI-SWNT复合物将RED以及UBQ10-EGFP等荧光质粒转化到油菜的原生质体和烟草叶片中。结果表明,PEI-SWNT纳米材料成功与外源目的基因结合,并对外源目的基因进行保护,使其免于核酸酶的降解,PEI-SWNT携带目的基因进入受体细胞后,可以成功地在受体细胞内进行基因表达。
To verify the effectiveness of a plant genetic transformation method mediated by single-walled carbon nanotubes(SWNT),binding ratio and protection of PEI-SWNT(polyethyleneimine single-walled carbon nanotube complexes)to exogenous genes were investigated and veritied.Carboxylated single-walled carbon nanotubes(COOH-SWNT)were used as raw material to construct PEI-SWNT modified with polyethyleneimine(PEI).Then PEI-SWNT complex was used to transform fluorescent plasmids(eg.RED and UBQ10-EGFP)into oilseed rape protoplasts and tobacco leaves.Results showed that PEI-SWNT nanomaterials successfully bind to the exogenous target genes and protect them from nuclease degradation.PEI-SWNT was found to carry the target genes into recipient cells and could successfully express them in recipient cells.
