In Shanghai Express (1932) and The Shanghai Gesture (1941) Josef von Sternberg piled dream-Pelions on the eastern Ossa, creating a Babel of mingling cultures and micro-political intrigue, of multivalent gambling, of polymorphous-promiscuous sexuality smoked, refined and narcotised in the land of the opium den.

Results showed that the PMC meiosis of autotetraploid was similar to the diploid except some particularities. In metaphase Ⅰ, multivalent, quadrivalent, trivalent, bivalent and univalent were observed and some of the chromosomes were found not to rank on the metaphase plate and so did in metaphase Ⅱ cells. In anaphase Ⅰ and anaphase Ⅱ cells, there were lagging chromosomes, chromosome bridge and fragment. During anaphase Ⅱ and telophase Ⅱ, chromosome segregation was not synchronous or equal. At tetrad stage, dyad, triad, tetrad with micronucleus and polyad appeared.

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量，延缓害虫产生耐受性，本文通过将携带有分别在高效复合OM启动子，CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3；反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin，GNA)基因；以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体，以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种，经体细胞胚再生获得了大批转基因再生植株。
