转基因技术在水产动物营养中的应用

摘要

近年来,随着分子生物学研究的进展,转基因技术得到了迅猛的发展,在水产动物营养中也有广泛的应用.动物转基因技术是指将外源基因或体外重组的基因结构导入动物的基因组内,使其在动物体内整合和表达,产生具有新的遗传性状,并能将这种性状稳定地传递给后代的一种技术.对转基因技术的一般方法,如显微注射、精子载体、电穿孔,逆转录病毒载体感染和基因枪等方法,以及转基因技术在水产动物营养中的应用进行了综述.%With the progress in molecular biology research ,a considerable progress was made in transgenic technology,which was wildly applicated in aquatic nutrition in recent years. Transgenic technology provides a method to rapidly introduce foreign genes or re-combinant DNA molecules into the genome of animals, which can incorporate and express steadily. This paper reviewed the general methods,such as microinjection, sperm mediated gene transfer, electroporation, retrovirus-mediated genetransfer, particle gun,and the application of transgenic technology in aquatic nutrition area.
