摘　　要：对动植物的研究结果表明，基质结合区（MARs）能提高转基因的表达水平，并能降低其在转基因个体之间的表达差异。本文着重综述了MARs的基本特征及其在转基因植物中的研究应用，对MARs在转基因动物方面的研究成果和MARs的作用机制也作了介绍。Matrix-attachment regions (MARs) have been identified that it can increase levelsof transgene expression and reduce transformant-to-transfomant variat ion of transgene expressionin both plants and animals. Some characteristics of MARs and the effects it have had on thetransgene expression in plants have been reviewed. At the same time, the effects of MARs ontransgene expression in animals and the impossible mechanism were also introduced.
