The vector harbored twin T-DNAs and the selective marker gene NPTⅡ expression cassette was separated in different T-DNAs from the GUS expre-ssion cassette in which two highly pathogen-specific inducible promoters, EAS4 and hsr203J, were used to drive report gene.
本研究用来自烟草的具有高度病原物特异性的两个诱导启动子EAS4和hsr203J,串联驱动GUS基因的表达,同时考虑到转基因植物的安全性,引入双边界序列,构建了含双病原物诱导启动子的植物安全表达载体。
This paper investigates the problem of the best weighted simultaneous approximation to totally bounded sequences (x_v) from a set G of generalized polynomials with restricted coefficients in complex normed linear spaces X.
在复赋范线性空间X中考察了具限制系数的广义多项式集G对全有界序列(xv)的加权同时逼近问题。
