随着转基因技术进入实用化阶段,其负面影响也逐渐显露出来,包括转基因品种对人类健康、生态环境等的安全性问题。但作为一种先进的育种手段,尽管人们对转基因技术有各种怀疑,其仍将在鱼类育种中发挥重要作用。一、转基因技术概述转基因技术是一种物种间的基因改良技术。转基因鱼是指将外源基因导入受体鱼的基因组内,并使其稳定整合并能遗传给后代的鱼类。目前,显微注射法是比较常用和有效的基因导入方法。近年来,作为分子生物学领域当 With the introduction of transgenic technology into the practical stage, its negative effects have gradually emerged, including the safety of GM varieties for human health and ecological environment. However, as an advanced means of breeding, it will still play an important role in fish breeding in spite of various doubts about genetically modified organisms. First, an overview of genetically modified technology Transgenic technology is a genetically modified between species technology. Transgenic fish refers to the introduction of foreign genes into the genome of the recipient fish, and make it stable integration and can be passed on to future generations of fish. At present, microinjection method is more commonly used and effective gene transfer method. In recent years, as the field of molecular biology
