转抗虫基因杨树外源基因表达的研究进展

The advances in expression of foreign genes in transgenic insect-resistance poplar

在转基因植物中,外源基因能否稳定高效表达对转基因植物的应用有重要作用。文章从转Bt基因杨树对鳞翅目、鞘翅目昆虫的抗虫效应,以及抗虫选择性、稳定性及毒蛋白表达等方面分析转抗虫基因杨树外源基因的表达特点,综述了近年来转Bt基因杨树外源基因表达的研究成果,以便为转基因杨树和外源基因的合理利用提供依据。

For the transgenic plants,whether or not the foreign genes can be efficiently and stably expressed plays an important role on the application of the transgenic plants.From the aspects of the insect resistance effect of transgenic Bt polar on Lepidoptera and Coleoptera,the insect resistance selectivity and stability,and the toxic protein expression,the expression characteristics of foreign genes in transgenic insect-resistance poplar had been analyzed in the paper.This paper reviewed the recent researches on foreign gene expression of transgenic Bt poplar,in order to provide the basis for transgenic polar and the rational use of foreign genes.
