摘要/Abstract

摘要： 简要介绍了水平基因转移（horizontal gene transfer,HGT）的基本概念以及进行转移的主要方式：由质粒或病毒等介导的水平基因转移和基因的“直接”水平转移。并结合基因组序列分析，重点阐述远缘生物之间发生的广泛的基因交流，以及其与进化、系统发育和基因工程生物安全性问题的探讨。
Abstract:In this paper the conception of horizontal gene transfer (HGT) was introduced,and main mode of HGT was also enumerated as follows:HGT by medium such as plasmid and virus etc.and the HGT without any medium.The transfer of genes from one species to another especially between remote species was emphasized by the information from genome sequencing.The problems about evolution phylogenies and safety of GEMs (gene engineered microorganisms) for HGT were discussed.
