US Patent Control of plant gene expression" was introduced in this paper. The patented technology genetically modifies plants in order to prevent seeds from germinating in the next generation. Farms who buy such sterile seeds will be able to harvest a crop, but will not be able to save seeds from their harvest. Seed company sees it as an incentive to develop new varieties.

美国公布的“植物基因表达调控”的专利技术,使经遗传改变的植物生产的下一代种子不能发芽。农民买了此一次性种子后,产量不受影响但不能留种用。种子公司把此技术作为开发新品种的一种手段。

Analysis of the large collection of genetically modified plants has shown that transgenes in a great of transgenic plants can't be expressed as expected. In some cases, transgenes are inactive and the transgene expression couldnt be detected throughly, which are called as gene silencing. Transgene silencing has greatly hinderred the application of the technic of plant gene transformation. Various factors seem to play a role, including of DNA methylation, transgene copy number and the DNA region where transgenes inserted. Basically there are two kinds of gene silencing, transcriptional gene silencing (TGS) and post transcriptional gene silencing (PTGS). According to the study on a mount of transgenic plants, several possible mechanisms by which silencing is achieved have been presented, such as RdRP cRNA , RNA threshold and RdDM models. The more understandings to the mechanisms will largely speed the research on plant gene engineering.

在转基因植物中外源基因不能正常表达 ,呈失活状态的现象称为基因沉默。造成基因沉默的因素主要有插入位置、重复序列和甲基化。基因沉默一般可以归为转录水平和转录后水平上。外源基因沉默阻碍了植物转基因技术在生产上的广泛应用 ,根据对大量转基因植物的分析和研究 ,人们提出了造成基因沉默的可能机制 ,如RdRP cRNA模型、RNA阈值模型以及RdDM模型等。深入了解外源基因沉默的机制以提高基因表达效率 ,是顺利开展植物基因工程的迫切需要

In this article we describe a rapid method capable of detection genetically modified plant with multiplex poly merase chain reaction (MPCR).We can detect several target genes at the same time with this method which raises greatly the efficiency of detection. We detect five soy bean samples and six soy bean dregs samples, at the same time we also detects them with general PCR method,the results between these two methods are consistent.
