查询词典 resistant

This paper took the insect-resistant transgenic birch grown in greenhouse for four years as study materials. The genomic DNA and RNA of leaves were extracted and the integration and the expression characteristic of the extraneous genes in the insect-resistant transgenic birch were analysed by methods of multiplex PCR, reverse primer PCR, inverse PCR, RT-PCR, and insect-feeding experiment of the transgenic plants respectively.
