title: [Horizontal gene transfer].
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.
