As many other countries , chinese consumers also demonstrate great variance in their acceptance and purchase will towards gm foods under different food categories . to be more specific , the consumers are most willing to accept and buy gm foods that improve nutrition , followed by pest - resistant types foods with those for extending shelf life being the least preferred 尽管如此，我国消费者对转基因食品的接受程度和购买意愿在不同的食品之间还是表现出了较大的差异，具体表现为：改善营养的最高，抗病虫害的次之，延长贮存期的最低；转基因植物性食品高于动物性食品。
However , it is necessary to acquire the antibody or the antiserum , which could specially react with the expression protein of die objective gene transferred into the transgenic plant according to the characteristics of high homology and immune cross - reaction among plant ferritin , using the special immune serum of pea ferritin , the content of plant ferritin could be detected for studing the ferritin expression of transgenic plant by the technique of immunoassay such as immunoprecipitation , eljsa and western blotting 利用免疫检测技术进行植物转基因的表达检测是一种简单、灵敏、快速、可靠的方法，但其前提条件是要有与转基因植物目的基因表达的蛋白质发生特异性免疫反应的抗体或抗血清。根据植物铁蛋白之间有高度同源性和交叉免疫反应的特性，利用特异性的豌豆铁蛋白抗血清，就可通过免疫沉淀、 elisa或western杂交等免疫检测方法进行植物铁蛋白含量等的检测，从而更好地进行转基因方面的研究。
Millet and tobacco were transformed with the thrt ' e plant expression vectors . our observations with transgenic plants showed that the pf40 gene affected the growth of lateral shoots developing in the basipetal pattern early after floral transition . analysisd the transgenic plants showed the pf40 gene can reduced the apical dominance of both millet and tobacco 测量结果表明pf40基因过量表达的转基因谷子生长素的含量降低为对照的0 . 6 0 . 8倍，而细胞分裂素的含量较对照约升高0 . 2 0 . 35倍，生长素与细胞分裂素的比值在转基因植物中改变明显，降低到对照的一半。
It has been estimated that the cost of producing proteins in transgenic plants may be 100 fold lower than in transgenic animals or mammalian cell cultures , and the possibility of using the plant tissue as a carrier for oral deliery could also diminish the expensie step of recombinant protein purification 估计在转基因植物中生产蛋白的费用比用转基因动物或者哺乳动物细胞培养的方法要便宜100倍，而且用植物组织可以作为口服递送载体，这点同样减少了高花费的重组蛋白纯化步骤。
